Dust Collection System InvestmentPerforming a lifecycle cost analysis is an overlooked step in evaluating a a dust collection system. Too often, focus is given to the purchase price of the equipment versus determining ongoing associated expenses. Read more on page 8
Dust Collection & Air Pollution Control Process dust and powders are controlled by the high-volume air cleaning offered by large-capacity dust collectors from Micro Air Clean Air Systems and its exclusive Roto-Pulse cartridge cleaning system. Read more on page 17
Pneumatic ConveyingThe J.D.B. Dense Flow pocket elbow is designed for use on pneumatic conveying pipelines, and is most effective when highly abrasive materials are being transported. Read more on page 20
Explosion Isolation Valve
Fenwal-IEP Technologies has released the ProFlapPlusIII passive isolation valve that is fully compli-ant with the new NFPA 69-2014 dust accumulation monitoring, flap blade-locking, and process shutdown requirements. The
ProFlapPlusIII is a passive isolation valve that self-closes by the pressure wave created by an explosion inside a vented dust collector and prevents flame propagation to upstream processes. The ProFlapPlusIII is ATEX certified for organic and inorganic dusts with KST values up to 300 bar.m/s for duct sizes ranging from 5 to 12 in. in diameter, and KST values up to 200 bar.m/s for duct sizes ranging from 14 to 40 in. in diameter.Fenwal-IEP Technologies, Marlborough, MA 855-793-8407 www.IEPTechnologies.com
Reinforced Plastic Hose
As a light suction and blast hose, the Protape TPE 321 offers the benefits of a fabric-reinforced hose: durable, abrasion-proof, and highly flexible, light, and compress-ible. In this version, the new hose is ideally suited for applications from the transport of powdery solids, through to gaseous media and steam extraction. It is also particu-larly suitable for blowers and compressors. The plastic hose can be used in operating temperatures of up to 110°C (short-term up to 125°C). It features small bend-ing radii and is kink-proof. The suction and blast hose is generally tape boxed and compressed which saves delivery costs and ensures minimum storage space.Norres Schlauchtechnik GmbH, Gelsenkirchen, Germany +49 (0) 209 – 80000 www.norres.com

Inlet/Outlet Chemical Isolation
OR
OR
Inlet Protection
Designed to react within milliseconds
of detecting an explosion, a chemical
isolation system can be installed in either
inlet and/or outlet ducting. The chemical
isolation system creates a chemical barrier
that suppresses the explosion within
the ducting, reduces the propagation of
flame through the ducting and minimizes
pressure increases within connected
process equipment.
Vertical PlenumA plenum that is bolted to the dirty air section of the collector. The explosion vent is mounted
to the top of the plenum which effectively transitions the pressure and flame fronts from a
horizontal to a vertical configuration. A vertical configuration make it possible to explosion
vent through a roof and/or direct the pressure and flame fronts to a safe location as outlined
in NFPA standards. In most cases, ducting and weather hoods are required to be compliant
with NFPA standards to protect the explosion vents from the elements and other debris.
Access panels are provided on the ducting so that easy inspection and/or replacement of
the explosion vent is made possible without removing the ducting and weather hood.

AND MORE
Explosion Venting Sequence

Fast-Acting ValveDesigned to close within milliseconds of detecting an explosion,
the fast-acting valve installs in either inlet and/or outlet ducting.
The fast-acting valve creates a mechanical barrier within the
ducting, which effectively isolates pressure and flame fronts
(from either direction) from being able to propagate further
through the process.
Blast PlateA Blast Plate is a deflector mounted directly in front the
explosion relief area. The deflector is designed to restrict
the flame length ejected from the collector in the event of an
explosion. For vessels that are not greater than 706 cubic
feet, the deflector is designed to reduce the axial (front-
centerline) safe distance by 50 percent.
ES465192_PB1408_004_FP.pgs 07.15.2014 00:48 UBM blackyellowmagentacyan
Flameless VentDesigned to install over a standard explosion vent, the
“FlamQuench SQ” extinguishes the flame front exiting
the vented area not allowing it to exit the device.
This allows conventional venting to be accomplished
indoors where it could otherwise endanger personnel
and/or ignite secondary explosions.
Chemical SuppressionDesigned to react within milliseconds of detecting an explosion, a chemical
suppression system is installed in the collectors dirty air section. The chemical
suppression system prevents expanding a deflagration by releasing a chemical
agent. This system is often used in order to put combustible dust collectors
inside the factory where you can’t vent to the outside.
Explosion VentDesigned to be the “weak” link of the vessel, explosion
vents open when predetermined pressures are reached
inside the dust collector allowing the overpressure and
flame fronts to exit to a safe area. Explosion vents minimize
damage to the dust collector caused by overpressure
created by a deflagration. Camfil APC’s standard explosion
vents are ATEX certified and NFPA compliant.
The purpose of the Stinger is to
prevent a deflagration (explosion) that
could occur in the dust collector from
traveling back down the inlet pipe
back into the workspace/process.
The iSMF has been proven to isolate the
downstream equipment from the progres-
sion of a flame front during an explosion.
The Farr Gold Series® dust collector with
an integrated Safety Monitoring Filter
allows you to recirculate exhaust air
back into the work space when your dust
is explosive. The key advantage of this
device is that it prevents the transmission
of explosive dust (fuel) from the collector.
Integrated Safety Monitoring Filter
Detect and SuppressThese systems protect the dust
collector from ignition sources such
as sparks or embers. It detects
them and activates a suppression
system that extinguishes them
before they reach the collector.

Mercury Intrusion Porosimeters
Provide Advanced Performance
and Safety
In addition to offering speed, accu-
racy, and a wide measurement range,
mercury porosimetry also permits the
calculation of numerous sample prop-
erties such as pore size distributions,
total pore volume, total pore surface
area, median pore diameter, and
sample densities (bulk and skeletal).
Micromeritics’ AutoPore V Series
mercury porosimeters can determine
a broader pore size distribution more
quickly and accurately than other
methods. These instruments also
include enhanced safety features and
offer new data reduction and reporting choices that provide more
information about pore geometry and fl uid transport characteristics.
The AutoPore V is available in two models to best match the require-
ments of quality assurance and research labs. The AutoPore V 9620
has a pore size range of 500 to 0.003 micrometers with two high-pres-
sure (60,000 psia maximum pressure) and four low-pressure analysis
ports. The AutoPore V 9605 contains two high-pressure (33,000 psia
maximum pressure) plus four low-pressure analysis ports measuring
pore sizes from 500 down to 0.005 micrometers.

Patented Bulk Bag Material Conditioner
Discharging bulk bags containing material that has solidifi ed, hardened,
or agglomerated can cause serious operational bottlenecks. Conditioning
and emptying bulk bags can be dangerous if the proper equipment is not
utilized. This patented system utilizes hydraulically actuated, heavy wall
tubular steel pivoting conditioning arms. Each conditioning arm features
“v-shaped” tubular steel breaker profi les that safely and effi ciently return
solidifi ed materials to a free-fl owing state. The
unit features a proprietary automated control
package that eliminates operator variability and
increases productivity. A powered rotary lift
table allows complete material conditioning of
the bulk bag on all sides, and top to bottom. The
unit features an ultra-compact footprint and
machine guarding for operator safety.

Silo Weight Monitoring and Control
Scale-Tron Inc. announces a major upgrade of the SiloWeigh.
Net inventory management and control system that moni-
tors the weight of material in silos or vessels located across a
very wide area. The information can be used to predict when
deliveries will be necessary, even if the user is not aware
of it, and allow appropriate action to be taken. For example,
deliveries for the next day can be scheduled rather than react-
ing to urgent phone calls. In addition, the system is claimed to
eliminate shutdowns due to empty silos as well as overfi ll and
its environmental consequences. Temperature compensated
bolt-on strain-gauge sensors on the vessel’s legs or skirt send
data via a digital transmitter at each vessel to the local area
computer network, where graphical displays can be viewed
on any computer. An overview shows all silos at the location
and individual trend graphs can show the usage and refi ll
patterns on any silo. Data is also transmitted via the Internet
or, when Internet is not available, the cellular radio network,
to the SiloWeigh.Net main database. This database allows data
retrieval via a secure Internet site to show levels in all silos as
well as trend graphs and alarm logs.

Ultra-Heavy-Duty
Bulk Bag Filling System
This new ultra-heavy-duty bulk bag fi ll-
ing system palletizes and fi lls bulk bags
with fi lter cake, aggregates, metal powders,
abrasive minerals, dry chemical additives,
and other diffi cult-to-handle bulk materials.
The system integrates a Swing-Down bulk
bag fi ller with a Flexicon pallet dispenser
and powered chain conveyor, allowing
safe, high-capacity fi lling of bulk bags of all
popular sizes, including bags with wide-
diameter spouts for passage of irregular
materials. When a fi lling cycle is initiated
by push button or contact closure, pallet dispenser forks lower the stack of pallets onto the
chain conveyor, withdraw from the bottom pallet, and raise the remaining pallets, allowing
the conveyor equipped with photoelectric eyes to move the dispensed pallet into position
below the fi lling station. The bag connection frame of the Swing-Down fi ll head lowers and
then pivots to a vertical position, allowing an operator at fl oor level to safely and quickly
attach bag straps to automated latches, slide the bag spout over a wide-diameter infl atable
spout seal, and press a spout seal infl ation button.

Understanding the Long-Term Value of Dust Collection System InvestmentsTravis Haynam
trahay@uasinc.com
Performing a lifecycle cost analysis is often an over-
looked step in evaluating the purchase of a dust col-
lection system. Too often, focus is given only to the
initial purchase price of the equipment versus deter-
mining the ongoing expenses associated with operat-
ing and maintaining the system. Perhaps the reason
for this approach is that many companies do not com-
pletely understand the relationship between proper
dust collection system design and configuration or
its impact on operational costs. Many of those initial
design decisions and configuration choices make the
difference between an effective solution which is a
sound return on investment or an inefficient system
that drives up operational expenses. If not properly
designed, the expenses to operate and maintain a poorly configured system will
rapidly exceed the initial purchase price.
The most expensive aspect of the dust collection system is the energy re-
quired to operate the air moving device. Therefore, investments that minimize
the horsepower requirement, such as reducing the required airflow volume
and operating static pressure, will yield significant long-term savings. Some
steps that will decrease the power requirement include having favorable inlet
and outlet conditions or utilizing an airfoil fan wheel to allow the blower to op-
erate more efficiently. Incorporating variable frequency drives (VFDs) is an ad-
ditional investment that can significantly reduce the blower operating expense
up to 30%.
Implementing poor duct design practices or selecting less than ideal duct ma-
terials will also negatively impact operating costs. For example, choosing to use
long sections of spiral duct or flex duct versus smooth duct may save money
on the initial material cost but long term, the additional friction added to the
system will increase the static pressure loss requiring additional horsepower
to maintain the desired performance. Upgrades to the hood design such as a
flanged or bell mouth hood will result in improved contaminant capture while
reducing system energy requirements.
Most dust collection systems utilize a reverse pulse jet arrangement to
clean filters and maintain system operating pressure. The associated energy
costs of these compressed air systems are another important cost to consider.
Taking steps to minimize cleaning frequency or choosing equipment which is
more effective per cleaning cycle are essential for controlling ongoing costs.
Incorporating an on-demand pressure controller that only cleans the filters as
necessary is also a sound investment that can further reduce longer term oper-
ating expenses. Choosing filter technology such as nanofiber that incorporates a
surface loading layer which improves the effectiveness of a cleaning cycle will
decrease the cleaning cycle frequency and lower maintenance costs.
Considering the lifecycle costs of a dust collection system investment is es-
sential in order to realize the full system value and maximize return on invest-
ment. Working with specialists within the industry who understand the impact
design can have on long term operating expenses as well as the value of prop-
erly configuring the system to match the process and application requirements
will yield significant savings over the life of the system.

Q: We had a community college install a dust collection system inside a room
next to their welding area. There are 32 welding stations and three grinding stations (with aluminum, carbon, and stainless steel dust) go into the collector. Can this collec-tor be inside without venting and what is the chance of fire or explosion?
A: I see two questions here: first, can a dust
collector be located inside under the cir-
cumstances you describe and the answer, in
theory, is yes. Please check NFPA Standard 484,
that strongly prefers dust collectors be located
outside for metal dust applications. However, ...

Explosion Isolation Valve
Protects Against Dust
Collector Explosions
Camfil Air Pollution Control offers
the Stinger, an explosion isolation
valve that isolates dust collector
explosions to prevent a deflagra-
tion from traveling back through
the inlet pipe of the dust collec-
tor into the workspace. Following
extensive testing, the Stinger is
the first U.S.-made explosion flap
valve to be certified by an inde-
pendent testing agency to comply
with NFPA standards. It may be
retrofitted onto most dust collec-
tion systems and used with new
or existing Farr Gold Series dust
collectors where the risk of a com-
bustible dust explosion exists. A
key feature of the Stinger valve is
a lightweight, patent-pending com-
posite blade that reacts with high
speed in the event of an explosion.
It closes faster than heavier steel
blades typically used for dust col-
lector inlet protection.

Pleated FiltersThere is not a single pleated filter element that meets the demands for every application, or even
a large group of applications. Variables include media, strappings, end cap materials, and manu-
facturing techniques. The filter combinations are near infinite, yet getting it right is critical. When
variables are misapplied, catastrophic failure will occur. Clarcor can help select a pleated filter for

Choosing Cartridge Dust Collector Filters for
Processing Applications
Cartridge dust collection systems are the preferred technology for most dry processing applications today, and there are many different pleated filter cartridges available for these collectors. As you face stricter air quality and combustible dust regulations, coupled with tighter internal cost controls, choos-ing and using the best dust collector filter for your process is more important than ever. Making an in-formed choice can improve your collector’s dust cap-ture efficiency and reliability while reducing energy and maintenance requirements.
Types of Filter MediaThere are two basic categories of media commonly used in pleated cartridge filters. The choice is usu-ally driven by dust type, operating temperatures, and the level of moisture in the process.
1. Nonwoven cellulosic blend: This media is the most economical choice for dry dust collection ap-plications at operating temperatures up to 160°F.
Sometimes the fibers will incorporate a coating that en-hances moisture resistance. However, cellulose media as a category are not as resistant to moisture as synthetic poly-ester.
2. Synthetic polyester me-dia or polyester-silicon blend: This lightweight, washable media can handle dry appli-cations with maximum oper-ating temperatures ranging from 180°F to 265°F. These filters are washable and can recover from a moisture ex-cursion but are not intended for wet applications.
Either type of media can be treated with a layer of nano fibers that boosts the efficiency and yields other benefits as well. Nano filter technology has advanced in recent years, and the newest generation of nano fibers can
perform well even in the most extreme conditions. When a layer of nano fibers is applied on top of the base media - whether cellulosic or polyester - the nano coating promotes surface loading of fine dust, preventing the dust from penetrating deeply into the filter’s base media. This translates into better dust re-lease during cleaning cycles and lower pressure drop readings through the life of the filter, which, in turn, promote longer filter life as well as energy savings.
Standard and nano filter media can also be treated with compounds that deliver special performance properties. Flame-retardant media are treated with a chemical that provides fire retardant properties for use where there is a risk of fire or explosion. Companies involved in metalworking processes such as plasma and laser-cutting, grinding, or welding commonly use filters with flame-retardant media.
Conductive or anti-static filters may be used where conveyed dusts generate static charges that require dissipation. Typically, static dissipation is achieved by impregnating a cellulose filter with a carbon coat-ing or a synthetic filter with an aluminized coating. Applications for these filters include fumed silica dust, plastic, PVC, or composite dusts, and carbon black/toner dusts. Cartridge filters with anti-static media can also be used in explosive dust applica-tions, making it possible to conform to NFPA re-quirements and lessen the risk of ignition sources due to static electricity charges. In combustible dust applications where the minimum ignition energy of the dust is below 3 millijoules (mJ), the NFPA requires the filters to be conductive, bonded, and grounded to the filter housing.
Selection TipsFollowing are five tips that can further help you de-termine the best filter for your application:
1. Understand the different measures of filter effi-ciency and how to apply them. There are two meth-ods that dust collector filter manufacturers typically use to express filter efficiency. Gravimetric analysis is based on particle capture by weight: For example, filter efficiency might be stated as 99.995 percent on particles of 0.5 µm or larger by weight. Filter efficiency may also be expressed as a Minimum Efficiency Reporting Value, or MERV, based on a scale from 1 to 16, with MERV 16 being the highest efficiency.
By Rick Kreczmer, Camfil APC
Conductive (anti-static) filters may be used where conveyed
dusts generate static charges requiring dissipation.

The MERV scale was developed for the HVAC filter market and does not take into account the way a dust collector operates (i.e., it pulse-cleans filters periodically when a dust cake builds up). Though MERV and gravimetric efficiency ratings are useful tools for comparing filters, you should not rely on these measures alone to determine efficiency. It is more relevant to make sure you are satisfying OSHA or EPA re-quirements for filter performance – OSHA if you are discharging the air and recirculating it indoors downstream of the collector, the EPA if you are discharging the air outside or into the environment.
Mass density efficiency, defined as the weight per unit volume of air, is the best predictor of a filter’s OSHA compliance. For example, OSHA might require that emissions will not exceed 5 mg/cu m at the discharge of the dust collector. Similarly, the EPA doesn’t care about percentage efficiency claims; they want to know that emissions will be at or below required thresholds, typi-cally stated as grains per cu ft or mg/cu m.
Concerned about which effi-ciency measure(s) to use? If so, you are not alone. But there is a way to cut through the confusion and make sure your bases are covered: Require your filter sup-plier to provide a written guaran-tee of performance stating that the filters you select will satisfy applicable OSHA or EPA require-ments.
It is worth noting here that ASHRAE is developing a new standard specifically for measur-ing performance of dust collector filters. Finalization of that stan-dard, however, is at least a couple of years away.
2. Test your dust. The collec-tion and testing of dust samples is a long-established practice used by processing professionals to make informed dust collection decisions. While dust testing has always been good practice, it is rapidly becoming a necessity in today’s regulatory climate.
There are two types of dust testing: (1) bench testing, which pinpoints physical properties of the dust, and (2) explosibility test-ing, which determines whether a dust is combustible.
Bench testing involves a series of tests that provide valuable data for filter selection. Particle size analysis reveals the dust’s par-
ticle size distribution down to the submicron range to determine the filtration efficiency needed to meet emissions standards. This test pinpoints both the count (the number of particles of a given size) and the volume or mass spread of the dust. Knowing both is important because many dusts are mixed.
A video microscope provides visual analysis of the dust shape and characteristics. Together with particle size analysis, this tool is vital for proper filter selection. For example, a microscope may be needed to detect oil in the dust.
Moisture analysis equipment measures a dust’s moisture per-centage by weight, providing information that can prevent moisture problems. A humid-ity chamber is used to see how quickly a dust will absorb mois-ture. This helps to identify hy-
groscopic (moisture-absorbent) dust which requires widely pleated filter cartridges, as these sticky dusts cause filters to plug. Additional bench tests can help to determine the optimal design of other dust collection system components. It is not necessary to bench-test dust 100 percent of the time, but if there is anything at all unusual about the process
and/or the dust, it’s a good idea. To determine whether a dust
is combustible, it should undergo separate explosibility testing as stated in NFPA Standard 68. If a dust sample is not available, it is permissible to use an equiva-lent dust (i.e., same particle size, etc.) in an equivalent application to determine combustibility. But once the dust becomes available, it is still recommended that you go back and test the dust using
either the 20-l test method de-scribed in ASTM E1226-12a or the similar method described in ISO 6184/1.
Using your dust sample, the lab will start with a screening test to determine whether the
Bench testing identifies physical proper-
ties of the dust, aiding filter selection.

official testing facility to confirm that this
dust collector can withstand an explo-
sive event. Scan QR code to view brief

Wear resistant pipe bendsJason Hunter, Pelletron Corporation
Pneumatic conveying of abrasive materials wears out standard, long-
radius pipe bends quickly. There are various types of pipe bends
designed for extended lifetime available. Pelletron developed a
special elbow that withstands the most abrasive materials.
Wear problems are common in dilute phase conveying systems
with high velocities. The conveyed product slides along the elbow wall
at a high velocity and high centrifugal forces press the conveyed material
against the outer metal surface. The resulting friction causes the elbow
walls to wear out quickly.
Pelletron developed a unique, patented conveying pipe elbow
that is trade named the Pellbow®. It is especially designed to minimize
damage caused when solid particles are injected into a high velocity con-
veying system — the higher the velocity, the higher the friction. Using
a Pellbow® avoids the problems caused by friction in traditional elbows.

By design, material fl owing through the Pellbow® forms a pocket or
“impact zone” and moves slowly upward and out. Incoming material
is defl ected at 90 degrees with minimum resistance and no impact
damage. The Pellbow® is wear-resistant making it the ideal solution for
conveying abrasive products. The Pellbow® is self-cleaning when the
material fl ow is stopped and it works in all installation positions.
Long-radius elbows or other types of pipe bends in existing vacuum
and pressure dilute phase conveying systems can be easily retrofi tted
with the Pellbow®. The pressure drop compared to long-radius elbows
is minimally higher. The minimum product-to-air ratio of 3:1 or higher
guarantees best results. The Pellbow® is designed to fi t all kinds of pipe
and tube connections.
The Pellbow® is available in aluminum, stainless steel and cast iron
for pipe sizes from 1.5” up to 12”, as well as in surface hardened versions.

dust is combustible. If the dust is not combustible, testing will stop there. If it is combustible, the lab will conduct further testing on dust cloud parameters to pinpoint the Kst (defined as the deflagra-tion index of a dust cloud, or rate of pressure rise) and Pmax (the maximum pressure in a contained explosion).
Explosibility testing is per-formed primarily to help deter-mine what explosion protection or prevention equipment is needed on your dust collector and related components. But it can also play a role in filter selection. For example, testing for the mini-mum ignition energy can help determine if conductive filters are needed.
3. Evaluate total cost of own-ership. When choosing between two cartridge filters with the same rated efficiency, some pro-cessors will regard these items as a commodity and simply choose the lowest-priced filter. But as with most purchasing de-cisions, initial cost is only one factor, and it requires a “Total
Cost of Ownership” (TCO) evalu-ation to make the best filter se-lection.
TCO helps you determine what it really costs to own your dust collector filters by calculating all the components of true filter cost: energy, consumables, and main-tenance and disposal. A reputable filter supplier should have soft-ware to help you perform the calculations. The TCO evaluation will ultimately save you money, time, and energy by ensuring the most cost-effective filter choice. (Note: A detailed article on TCO appeared in the August, 2010 is-sue of Powder & Bulk Solids and can be accessed at www.powder-bulksolids.com.)
4. Consider a nano fiber me-dia even if you do not have a “difficult” dust challenge. When they were first introduced to the market, nano fiber media were regarded as a high-end choice lim-ited to exotic or demanding dust-capture challenges. Though these filters carry a cost premium, their use is becoming more widespread for all types of applications as
processors come to understand their benefits. Compared to stan-dard media, nano fiber filters of-fer higher filtration efficiencies as well as better energy perfor-mance, superior cleanability, and greater resistance to wear and tear from pulse-cleaning. Because of these benefits, some filter ex-perts believe nano fiber media will become standard in the fu-ture.
As a rule of thumb, if you are looking for high initial filtration efficiency and better release of dust through surface loading, then nano fiber media should be the default choice. Beyond this, even for a “non-high-perfor-mance” application, a TCO analy-sis (above) might be worthwhile to find out if the added cost of nano fiber media will be more than offset by resulting savings in energy and filter change-out and disposal costs. In a system operating at very high airflow, for example, a half-inch reduc-tion in pressure drop achieved with a nano fiber filter can make a huge difference in energy con-sumption.
5. Look for a uniform wide pleat media design. Many filter manufacturers add filter media to the point where the pleats are so tightly packed that when dust gets between the pleats, the re-verse pulse cleaning system of the dust collector will not eject the dust from the pleats. This in-creases the resistance of the air through the filters and diminishes airflow. The key is to use a wide pleat where 100 percent of the media is usable.
A wide pleat filter allows the collected dust to release from
the filter, keeping the resistance lower through the filter for a lon-ger time. Some wide pleat filters use state-of-the-art technology of synthetic bead pleat separators to ensure pleats are kept wide and open for the best dust release possible. These separators pre-vent the media from folding over on itself, which could cause the filter to plug.
A wide pleat filter will often contain less total media area than a tightly pleated model. But the total square footage of the media is not what you want to look for: It’s the total usable media area that’s really impor-tant.

Spark Detection and
SuppressionThe pneumatic conveying of com-
bustible dusts carries inherent
risks for dust fires and explosions
in many applications. Grinding,
cutting, and drying operations can
often cause sparks that are typi-
cally the ignition source for fires
and explosions in duct collectors
and air filtration equipment. The
FLAMEX system is specifically de-
signed to address these hazards by
detecting and suppressing sparks
in the pneumatic ductwork before
they can reach dust collectors or
storage bins. Infrared detectors
sense sparks being transported
through ductwork to a dust collec-
tor. The system then triggers an
extinguishing device located down-
stream from the detectors and ef-
fectively extinguishes the spark.

Low-Pressure Continuous Dense Phase
Convey System for Fragile Material
The E-finity is a patented continuous dense
phase convey system for fragile materials.
Precise pressure monitoring and airflow cor-
rections allow the system to operate efficiently
under all conditions, while gently inducing
materials through the convey line in slug form.
E-finity is ideally suited for granular and pel-
leted materials, and has proven itself on many
projects for pet foods, cereals, nuts, grains, and
prills. E-finity air controls can employ a single
air source to operate 2-3 different systems si-
multaneously. The result is a cost savings in
both equipment and installation, with contin-
ued savings in operation and maintenance mov-
ing forward.

Patented ECOPhase Pneumatic Conveying System
The patented ECOPhase pneumatic conveying technology uses a
specially designed entrainment device called a “Magveyor” to al-
low a system to operate continuously while achieving high solids
loadings and allowing the conveyor to run more efficiently. This
can be of advantage to a manufacturing facility in either of two
ways: it will allow a new installation to reduce the horsepower
needed to convey dry bulk solids for a given rate and distance,
or it will allow an existing installation to run more efficiently on
existing horsepower, increasing the maximum throughput for a
given line.

ors are engineered with a PD pump or
regenerative blower to create vacuum
without the need for plant air, increas-
ing energy efficiency and lowering oper-
ating costs. Its tool-less, side-door filter
access provides installation flexibility
– even allowing mounting near the ceil-
ing, and making cleaning fast and easy
run after run. These vacuum conveyors
move products vertically, horizontally,
around corners, on multiple levels, and long distances with minimal opera-
tor attention or maintenance. They are ideal for conveying powders, dusts,
granules, flakes, and pellets in continuous or batch processes.

Mini-Fluidizer Promotes Material Flow
Solimar Pneumatics has added a smaller version of its disk-type fluidizer. This 2-in.-diam Mini Disk
fits in pipes, chambers, chutes, and small hoppers to enhance flow of powders and dry bulk mate-
rial in pneumatic conveying systems. Because of its compact size, the Mini-Disk fits in curvatures as
small as 4 in. In all applications, these fluidizers prevent bridging, rat holing, and material hang-ups.
The aeration of the disk fluidizer utilizes directional air flow along the wall of the chamber or pipe to
loosen product and move it to the discharge point. Gentle vibration is provided at the outer edges of
the disk to keep powders and bulk solids flowing. Because the disk seals tightly against the chamber
or pipe wall, there is minimum back pressure. This design advantage also prevents airline plugging.
All Solimar aerators are compatible with food grade materials and are FDA approved.

Pneumatic Conveying of Highly Caustic,
Corrosive Material
Specially treated to transfer a highly corrosive,
granular material, this pneumatic conveying
system uses integrated automation to mini-
mize human exposure to the material and to
optimize process efficiency with the upstream
bulk bag unloading system. To reduce wear, the
pneumatic conveying system is constructed of
specially coated stainless steel tubing and com-
ponents. Process-critical components and valves
are Teflon coated. Pneumatically conveyed ma-
terial is transferred to the downstream wetting
process, in batches, based on calls from weigh
system sensors. Total system capacity exceeds
9500 lb/hr. NBE integrated automation central-
izes system control, communication, monitoring,
and reporting using NEMA 12, dust-tight enclo-
sures, and a single, UL-listed HMI.

Conveying Process
for Plastic Production Plants
The pellcon3 conveying process pro-
vides a solution for plastic processors
who are upgrading existing plants or
building new ones. This technology
consists of the three process compo-
nents: Strandphase conveying, Pellbow
pipe bends, and the DeDuster for fines
removal. Unlike dense phase systems,
the pellcon3 process does not create
dynamic forces throughout the line,
reducing costs for building construc-
tion and silos. Maximum conveying
pressure is below 22 psi, making use
of medium pressure rotary valves and
blowers possible, and the flexibility of
turndown ratios in a Strandphase system
allows operation without an additional
air management system. With pellcon3,
conveying line sizes are smaller than
in dilute phase or dense phase systems,
and the efficient use of energy provides
additional savings in the ongoing cost of
operation.

High-Pressure Blowers
The conveying of material-laden air with
fans involves determining the bulk density
of the material to be conveyed. An appropri-
ate amount of dilution air will be determined
and a fan selected. High-velocity air is used
to carry dirt, weld fumes, grain, plastic ma-
terials, wood waste, and paper trim from a
process to a collection point. BC pressure
blowers are designed for high-pressure, indus-
trial-process applications. All applications can
be handled in either induced-draft or forced-
draft configurations. Modifications and accessories make BC pressure blowers
suitable for a wide range of systems, especially pneumatic conveying.

Food and Pharma Vacuum Conveyor
A new conveyor line from Piab, piFLOWp
meets the high demand from the food and
pharma industries. The vacuum generated by
piFLOWp is produced in an energy-efficient
way, utilizing Coax cartridges. The Coax car-
tridges are smaller, more efficient, and more
reliable than conventional ejectors, which
allows for the design of a flexible, modular,
and efficient vacuum system. A vacuum sys-
tem based on Coax technology can provide your customer with three times more
vacuum flow than conventional systems, while reducing energy consumption. pi-
FLOWp is designed according to USDA and GMP guidelines. All materials are FDA
approved and all configurations can be delivered with an ATEX Dust certificate.

Heavy Duty Material Handling Hose
Tigerflex Voltbuster is a lightweight, thermoplastic material handling hose that safely dissipates
static charge in extremely high-static applications. The Voltbuster hose solves the problem of in-
dustrial hose propagating brush discharge, otherwise known as “hose arcing,” which occurs when
the static generated inside the hose overloads the dielectric strength of the hose tube. The conse-
quences of electrostatic discharges range from personnel experiencing serious physiological shock
to a potentially fatal dust cloud explosion. The hose can be used at any facility handling powders,
plastics, or other granular materials, offering a lightweight alternative to cumbersome metal and industrial rubber hoses. The hose can be used
without workers’ fear of getting “shocked,” while at the same time being lightweight and flexible enough to maneuver without worker strain.

Pneumatic Air-Vey Magnets
Air-Vey magnets are designed to remove ferrous contaminants from products
in dilute-phase pneumatic conveying systems that operate at 15 psi or less.
These units are used to ensure product purity and protect process equip-
ment. The flow-through area of the housing is engineered to maintain the
same product velocity without an appre-
ciable drop in pressure. These magnets
install easily in horizontal, vertical, or
angled positions with compression-type

Pneumatic Weigh Filling System
This pneumatic gain-in-weight filling system conveys and
weighs free-flowing bulk solids, and discharges the material
into bulk bags dust-free. The filter receiver of a Pneumati-
Con vacuum dilute-phase pneumatic conveying system is
mounted on load cells, enabling the controller to stop the
flow of material once an accurate batch weight has been
accumulated. A “fill” button on the Twin-Centerpost bulk
bag filler actuates a blower to remove bag creases, and then
opens a slide gate valve to discharge the batch into the bag
at high rates, as a vibratory deck densifies the material to
stabilize the bag. The filler is mounted on a secondary set
of load cells to check-weigh the filled bag. A port within the
discharge spout vents displaced air and dust to a remote
bag house. The controller then releases the bag straps and
deflates the spout seal, allowing the operator to tie-off the spout and remove the filled bag.

Pocket Elbows
The Dense Flow Pocket Elbow is designed for use on pneumatic conveying pipelines, and is most
effective when highly abrasive materials are being transported. During a pneumatic convey cycle,
the elbow traps incoming material at the elbow’s deflection point. The material that is trapped in
the “pocket” then acts as a barrier for any remaining material being conveyed, and greatly increases
the lifespan of the elbow. The Pocket Elbow can directly replace any existing pneumatic elbow
when combined with Dense Flow Pipe Stubs. The advantages of the Dense Flow Pocket Elbow are
increased elbow lifespan, less downtime, lower maintenance costs.

Flex Tube Diverters Eliminate Cross-Contamination
Vortex Flex Tube Diverters eliminate material cross-contamination commonly found in the food,
plastic, and chemical industries. They are ideal to divert, or converge, a wide range of dry mate-
rials, including sugar-based solids, in gravity or dilute phase pneumatic conveying systems. Flex
Tube Diverters feature two or three ports that utilize a basic sliding orifice blade design. A tube
stub is welded to an orifice-style blade, and a flexible hose is then attached to the tube stub. As
the diverter blade is shifted, a flexible hose moves from one port to the other, allowing the con-
venience of continuous conveying. When one port is open, the other ports are sealed and elimi-
nates any internal ledges or pockets where material can become lodged and remain trapped.

Dense Phase Pneumatic Conveying Systems
Dynamic Air pneumatic conveying systems handle a wide range of materials and
bulk densities at rates from 500 lb/hr to 450 tn/hr, over distances to 6000 ft. Each
system is custom-designed from one of 16 different conveying concepts to provide
a conveying solution that fits the process perfectly. One conveying concept, the
Full-Line Concept system, has many advantages over more traditional dense-phase
concepts with regard to degradation and energy consumption. In addition, it is
clean and totally enclosed and can be fully automated to convey to packaging or
process bins. Few moving parts are utilized, as the prime mover is standard plant
compressed air at 100 PSIG. Cross contamination is never an issue as the convey-
ing line can be purged clean when switching between materials.
Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com
Blow-Through Feeder/Airlock
Fine powders can easily over-aerate, which reduces material feed efficiency in high-pressure
pneumatic conveying applications. ACS Valves designed the BT Series blow-through feeder/
airlock to ensure optimal throughput of hard-to-convey materials. The BT Series 12-vane rotary
valve design decreases excess aeration of the material during conveying with an integrated
vent port on the return side of the valve housing that vents
pocket air leakage. The BT design element minimizes the
flow path of air through the rotor clearances, improving ma-
terial pocket release. With minimal air leakage, the resulting
low, effective pressure drop of the BT Series optimizes ma-
terial flow density, improves material conveying efficiency,
and reduces total compressed air consumption.

Figure 1 - Dust Explosion Pentagon
I
Secure Cloud-Based Industrial Monitoring Solution
It is well known that transporting certain dry dusty materials can create explosive atmospheres. Five conditions, known as the “Dust Explosion Pentagon”, have to exist in order for the explosive state to oc-cur. First, there needs to be a high concentration of dust (fuel), followed by an ignition source (heat) and oxygen (oxidizer). If all of these appear in a confined space with dispersion, an explosion can occur. The most common ignition sources have long been iden-tified as over-heated bearings, misaligned belts, and belts that are slipping. The industry is saturated with various sensors and controllers that monitor these conditions to prevent explosions. Regardless how well these systems work there is one problem with all of them: human error. With the ever-growing demands on site performance and efficiency at ter-minals and processing facilities, decisions to bypass
safety equipment has become an ever increasing is-sue. With mount-ing pressures, site personnel may risk keeping a machine in opera-tion even after an alarm has been detected, putting the plant and all personnel at risk. Without backend reporting systems and data logging, this dangerous practice can go on undetected by up-per management.
In order to combat this issue, 4B Components has developed a solution that in-
troduces a greater level of transparency and record keeping. HazardMon.com is a secure cloud-based industrial monitoring solution that allows any regis-tered user to log in and see all their facilities in real-time from anywhere in the world. This product of-fers seamless integration with 4B’s T500 Elite Hotbus hazard monitoring system.
HazardMon.com FeaturesFeatures of the HazardMon.com include the follow-ing:
• Secure login and data transfer with standard 256-bit (SSL) encryption, or an optional virtual private network (VPN) connection can also be created
• No server or PLC is required, so there is no ad-ditional hardware to replace or backup, which also eliminates upkeep and upgrade costs.
• Data is sent directly to 4B’s cloud server, and automatically backed up in multiple off-site locations making the data extremely safe and secure. This al-lows data to be easily recovered and analyzed in the case of an on-site event, such as an explosion.
• Live system dashboard, historical data, and cus-tomizable graphs can be viewed on any Web-enabled device (smartphone, tablet PC, desktop or laptop computer).
• Email alert notifications can be sent to notify specific users whenever a change in the system’s health is detected.
• New features are constantly being developed to improve the end user experience, and with HazardMon.com’s cloud-based technology, your facil-ity will always be at the leading edge of technology.
Live System DashboardWith HazardMon.com it is possible to view multiple sites from one system dashboard page (see figure 3).
This unique feature varies from other systems where you have to log in to each site individually and view them one by one. HazardMon.com also indicates all active alarms from all facilities in one place as soon

as you log in, allowing managers to see any problems in a matter of seconds.
All sensor data can be viewed in real-time using any standard Web browser such as Mozilla Firefox, Google Chrome, or Internet Explorer (see figure 4).
The Web site is completely dy-namic and the sensor status and value are updated automatically without the need to refresh the webpage. The Web site was de-signed to dynamically resize as the screen resolution changes and it is optimized for tablet and mo-bile phone platforms.
Historical Data AnalysisAll data can be viewed as graphs. A unique drag-and-drop feature allows you to pick specific sen-sors of interest and compare them side-by-side in one graphical view (see figure 5). Time windows can
be selected, ranging from 1 hour to 30 days. The graphs are inter-active, allowing you to use your cursor to mouse over any event to show specific values and sen-sor statuses.
All alarms are stored in a sepa-rate alarm log (see figures 6 and
7). Using the Web site filtering options, it is easy to generate a report and download it into a standard spreadsheet program. All the alarms are grouped into different alarm types, like “Alarm Detected”, “Alarm Cleared”, “Device Power Up”, etc. This al-lows information to be extracted in a few clicks and create a report in seconds.
Email and Text (SMS) Notifications EngineA flexible notification system al-lows any user to receive email or text message notifications.
Notification can be sent when sensors go in and out of alarm; when the Internet connection between the T500 Hotbus system and the server is lost or when an alarm has not been cleared for a number of minutes. It is also possible to receive notifications only when an alarm has not been cleared for a specified number of minutes.
Report Generation ToolAn advanced analytics tool allows reports to be generated that sum-marize the safety and efficiency of the factory. Currently it is pos-sible to see which sensors caused the majority of alarms, which hours of the day had most alarms, and the types of alarms. (See fig-ures 8 and 9) The start and end

dates of reports can easily be al-tered and the report re-generated. Reports can be saved to the user’s PC in a single click.
Automated Maintenance and Testing FunctionalityIt is important to periodically check that your monitoring sys-tem will detect an alarm when a dangerous condition occurs. The current standard in the industry is for technicians to walk around the site and manually test each sensor. A paper report is then generated and in some cases, converted into a digital format (Microsoft Excel for example). There is still absolutely no guar-antee that the technician actually
performed any of the testing. HazardMon’s sensor testing func-tion ensures that test procedures are carried out, logged, and re-ported within the system. This feature provides managers docu-mented evidence that each sen-sor has been tested to ensure it is working correctly. (See Figure 10).
To initiate a system test, a user would go to the “Maintenance” tab within HazardMon.com and choose a sensor to test. During testing, HazardMon temporarily stops alarm notifications for this sensor, so that no nuisance alarm notifications are sent out. The user has five minutes to trigger an alarm and confirm the sensor is in proper working condition or needs to be replaced. The whole process is logged automatically, and a maintenance report can be generated after testing has been completed.
ConclusionAs more facilities install moni-toring systems to ensure the site’s safety, the main safety concerns, human error, and the lack of transparency still exist. HazardMon.com combined with 4B’s hazard monitoring systems gives management real-time ac-cess to all critical monitoring data. This increases transparency, cuts down on human error, and helps to verify that company safety poli-cies are being adhered to. To see all of the features avail-
able, sign up for a free demo ac-

Compact Vibrating Rod for Small Bins
BinMaster introduces the new CVR-625 mini vibrating rod, a
compact point level control designed for use in small bins and
hoppers where other level sensors will not fit. The new ver-
sion features an updated design that allows for the detection of
light materials with a bulk density as low as two. The rod can
be used for measuring plastics, food, seed, chemicals, and other
pellets or dry granular solid materials. The signal from the elec-
tronic circuit of the CVR-624 excites the single rod of the instru-
ment to vibrate on its resonance frequency of approximately
460 Hz. When material covers the rod of the probe, the vibra-
tion stops. This is sensed by the electronic circuitry that forces
its output relay to switch. When the blade becomes uncovered,
the vibration will restart and the relay will switch back. Due to
its vibrating technology, the mini vibrating rod is able to over-
come the difficulties associated with changes in dielectric con-
stant, humidity, temperature, and material density, and elimi-
nates the problem of false signaling due to material wedging and
buildup associated with Ôtuning forkÕ type probes.

High-Tech Plastics Are Economical and
Environmentally FriendlyOne of the greatest advantages of plastic is that it
can replace heavier metal – resulting in more light-weight automobiles. DuBay Polymer GmbH is one of the world’s largest plants for the production of high-tech plastic. During the refinement process of com-pounding, a variety of dusts and fumes are created that must be reliably extracted.
DuBay Polymer in Hamm-Uentrop annually pro-duces up to 80,000 tons of polybutylene terephthal-ate (PBT). The polymer is the primary component of premium plastics that are utilized in numerous in-dustries because of their flexibility. DuBay was estab-lished in 2001 as a joint venture between LANXESS and DuPont and has been experiencing steady growth in recent years.
Lighter Plastics TrendA driving force behind this development is the current trend toward replacing met-als with durable and versatile high-performance plastics, or utilizing both materials as a composite (hybrid technol-ogy).
“One advantage of plastics compared to metal is the fact that the components are lightweight, resulting in lower fuel consumption, lower costs for the auto-mobile owner and reduced CO2 emissions. A significant advantage for the budget and for the environment,” stresses Michael Pasch, the materials processing engineer responsible for the com-pounding system.
By adding a bulking agent, fibers, and other additives, the PBT polymer achieves certain targeted character-istics in such a treatment process. DuBay employees can produce plastics sturdy enough for use as compo-nents capable of withstand-ing heavy use loads such as hinges, housings, heavy foot traffic, or ease of access de-vices. “Because of their heat
resistance, automotive suppliers also utilize these plastics in components which are subjected to high temperatures, such as headlight mounts,” adds Pasch.
Dual-Stage Separation TechnologyIn the beginning of 2012, DuBay introduced a second compounding system and thereby doubled its capac-ity for high-end plastics. During the planning stages, the system operators requested improvements to the existing labor-intensive extraction process. The key recommendation was provided by Lanxess, the parent company, which has experienced long-lasting results with Keller separators, especially for plastic refinement processes.
The requirements of Pasch and his colleagues are consistent with the two-part filtration technology used by Keller for compounding processes. “First we separate dry dusts created during the weighing, mixing, and addition of additives by utilizing a dry separator. Then, any adhesive aerosols released dur-ing extrusion processes are separated by a wet sepa-rator,” explains Nick Herfurth, vice president of sales and operations at Keller.
Decreased Sludge Facilitates DisposalThere is a frequent risk of deposit buildup and fires inside the ductwork. To offset this risk, Keller employs spray nozzles that rinse the dirty air duct with water over the entire surface. “The evaporative cooling creates a sudden temperature change which results in the condensation of high boiling point solvents,” says Herfurth. The subsequent wet separa-tion removes liquid in addition to solid particulate from the exhaust flow and separates them from the waste water in the sedimentation basin. The result-ing sludge is discharged automatically and continu-ously by a sludge remover and sinks into an adjacent disposal container. “We are pleased that we no lon-ger remove the sludge manually – the operation is now much simpler and a cleaning is seldom neces-sary,” Pasch adds.
“The fact that dust generated at the mixing platforms is extracted by a separate dry separa-tor further reduces the amount of sludge that ac-cumulates in the wet separator,” says Pasch. “This facilitates disposal and is more economical. In ad-dition, the dry separator is very easy to maintain. The filter element cleaning is controlled automati-cally by differential pressure or at pre-set time intervals. Full disposal containers can be emptied during operation. The level monitor indicates – Keller dry separator Vario

normally after an interval of some weeks – that the container can be emptied.
Dry Separation Process Must Meet ATEX GuidelinesThe requirements of the ATEX guidelines apply to the operation of a compounding system (explo-sion protection guidelines of the European Union). The Vario dry separator is equipped with a high-quality pressure relief valve that can flamelessly absorb any energy created in the unlikely event of an explosion. One of Keller’s pat-ented back pressure flaps can pre-vent the spread of the shock wave and flames into the workplace.
Reliable Filtration Provides System ReliabilityPasch and his colleagues manage the compounding system from their control station. A number of monitors and displays assist them. “We only leave if a mal-function message is displayed and this rarely occurs,” says Pasch. The high reliability not only fa-cilitates the operator’s work, but also boosts the rate of produc-tion. “The separation operates
smoothly nearly without supervi-sion,” says Pasch.
When asked if Keller would be considered for the potential purchase of a third compound-ing system Pasch said, “Keller is one step ahead as far as filtra-tion technology is concerned. Of
course they would be in conten-tion.”

The new Silo Sweep Auger from Guttridge Ltd is a
robust machine for the automated emptying of grain
silos. Grain silos empty under gravity but as grain lev-
els drop this process stalls. One option is to dig out the
residual volume manually, but this incurs substantial
labor costs and raises HSE issues. The alternative is to
use a sweep auger, which as the name suggests, sweeps
across the silo floor, transferring the remaining grain via
a screw to the silo outlet. The Silo Sweep Auger is made
from galvanized steel to improve longevity and reduce
the risk of product contamination from flaking paint.
Rubber blades ensure an efficient sweep of the silo
floor while an enclosed clutch and motor mechanism
prevents grain ingress and subsequent damage, improving reliability. The patented drive design
delivers the very highest levels of efficiency by reducing slip and strain within the system.

Dust Collection & Air Pollution Control
ProductFocus
SpaceSaver High-Efficiency
Dust Collector
The SpaceSaver dust collector is up to 75% smaller than tra-ditional dust collectors, offering long-lasting, leak-free cartridges. With a footprint as small as 27 x 38 in., the SpaceSaver is suited for applications with limited space re-quirements in terms of both cross-section and overall height, as well as in areas of the plant that aren’t connected to central dust collec-tion systems. Many cartridge styles are available to best fit the appli-cation, with sizes ranging from 2 to 48 cartridges per collector. The SpaceSaver uses directed air flow fire to pulse the cartridges. Schenck Process, Whitewater, WI 262-473-2441 www.schenckprocessinc.com
Modu-Kleen Downdraft Series
Dust Collector
The Modu-Kleen downdraft dust collector contains fugitive dust. The air enters at the top of the dust collector housing and flows downward to the cartridge filters, improving the filtering process and the material-to-air ratio. Air veloci-ties are lower than those with a conventional dust collector, reduc-ing the load on each filter car-tridge and extending filter life. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com
High-Temperature Wax Technology for Induction Seal Liners
Tri-Seal has introduced a high-temperature wax technology designed to bolster the stability of two-piece induction seals that are stored or distrib-uted in challenging high-temperature conditions. The solution is specifi-cally engineered to reduce costly (and potentially dangerous) seal-related product leakage from packaging closures. This is a particular cause of concern for lined closures and seals shipped or stored in high-temperature conditions, such as those found in India, Israel, Southeast Asia, Australia, Puerto Rico, and Latin and South America, as well as southern American states and, more seasonally, throughout greater North America. When exposed to high temperatures even for brief periods, the wax component of a two-piece induction seal can be prematurely absorbed into the pulp layer prior to closure application, thereby potentially compromising seal integrity during the filling and capping process. Often, the result is a “potato-chip effect” whereby the heat seal portion of the circular seal’s outer edge curls and separates from the backing material. During capping, the heat seal portion can fold under and not fully seal on the bottle finish. The ensuing leakage is a particular problem for companies who manufacture and distribute highly sensitive or unstable products, such as those found in pharmaceutical, agricultural, chemical, and au-tomotive industries.

• Particle Analysis
Morphologi G3-ID Characterizes Discrete Particle Populations within Powder Blends
The Morphologi G3-ID from Malvern Instruments is a powerful particle characterization system that combines
automated imaging with Raman spectroscopy. Using these technologies, it delivers component specific particle
size and shape distribution data for discrete populations within a powder blend. One application is in the analy-
sis of environmentally friendly cements, where a proportion of clinker is replaced with ‘waste’ materials, such
as blast furnace slag or fly ash. For most cements, laser diffraction particle sizing meets routine analysis re-
quirements. However, for cements containing
replacement materials it is often necessary to
measure the particle size of individual compo-
nents within the blended product. Morphologi
G3-ID provides statistically relevant particle
size and shape data for each component, even
where these are morphologically similar. These
data are helping manufacturers optimize the
performance of newer cements and manage development and future production costs.
Malvern Instruments Inc., 508-768-6400 Westborough, MA www.malvern.com
Particle Insight Size and Shape Analyzer
Particulate Systems’ Particle Insight is ideal for ap-
plications where the shape of raw materials – not
just the diameter – is critical to the performance of
the final product. The instrument offers up to 28
different shape parameters analyzed in real-time in
either aqueous or organic solvent suspensions. The
Particle Insight operates in a range suitable for a
wide variety of industrial, biological, and geological
specimens from 1 to 800 micrometers. Its unique
recirculating sample module and precision optics
are designed to acquire and report statistically valid
measurements quickly, an essential quality con-
trol capability in many manufacturing processes.
Particle Insight features include the ability to track
sample shape changes over time as well as the capability to store a collection of particle images.
The user has the option of viewing only those particle images that meet any combination of the
analyzer’s 28 shape parameters. It also has an automated fill-and-rinse feature allowing for true
unattended operation.

Inflatable Seated Butterfly ValveAn inflatable seated butterfly valve designed for dry bulk solids or liquid slurry applications is available from Posi-flate. The valve is ideally suited for abrasive materials such as sand, feldspar, fly ash, and most other dry, granular materials, which reduce valve life. The inflatable seat design pro-vides a better seal by utilizing air pressure to expand the seat against the disc, providing more sealing area and an even pressure distribution against the disc every time. The seat automatically compensates for wear when it inflates against the disc, extending valve life considerably. Standard sizes range from 2 in. (50 mm) to 30 in. (750 mm). The valves are available in a wide variety of construction materials including stainless steel and lightweight aluminum.
Posi-flatewww.posiflate.com

Low Cost Alternative to Rotary Airlock ValveAerodyne’s Vacu-Valve is one of the lowest-cost, lowest-main-tenance dust collector valves available. The Vacu-Valve comes in two designs; both the open-construction of the Platypus and the closed construction of the Armadillo offer a cost effective alternative to rotary valves in certain applications. A vacuum operated valve is suitable for continuous discharge applications that have dense, free-flowing material such as sand, coffee grounds, as well as other industrial particulate. This trickle valve system operates as a constant discharge valve for dust collectors, hoppers, and other pollution control equipment operating under negative pressure. Its unique bill design allows it to dispense free-flowing material continu-ously.
Aerodyne Environmentalwww.dustcollectorhq.com
Slide Rail System for Easi-Clean Tapered Rotary AirlockThe Bush & Wilton Easi-Clean tapered rotary airlock is now offered with a slide rail system. With this design, the slide rail system will support the rotor and end cover upon removal, while incorporating the Easi-Clean system which allows for rotor removal without disconnection of the drive. In addition, this rotary airlock contains the Bush & Wilton tapered rotor feature which allows for rotor clearance adjustment in the field to compensate for temperature, wear, or product variations. This rotary airlock would typically be used in food or sanitary applications, where the valve’s internals need to be cleaned on a regular basis. Also, it can be used in applications that require frequent product changeover.
Bush & Wilton Inc.www.bushandwilton.com
Rotary Valves Deliver High Performance Feeding RVS-type blow-through rotary valves have been developed in accordance with the criteria of meeting a maximum scope in application. They have been designed for the controlled discharging of powders or granular materials from silos, bins, hoppers, cyclones, or dust collectors into low- and medium-pressure pneumatic conveying lines. RVS blow-through rotary valves consist of a tubular cast iron or stainless steel casing, a horizontally mounted rotor with a defined number of oblique V-shaped cross section compartments, a drive unit, and a casing cover at each end. To provide long-term, heavy-duty feeder performance with differ-ent materials, numerous rotor and body surface treatments such as nickel plating, Teflon coating, and hardened chromed plating can be provided.

Elevate, tip and dischargeboxes/containers dust-freeTIP-TITE® High-Lift Box/Container
Dumper discharges dust-free
into vessels 6 to 10 ft (183 to
305 cm) high. Accommodates
containers 36 to 48 in. (915 to
1220 mm) on a side, and 39 to
44 in. (990 to 1117 mm) in
height. Hydraulically raised
container platform creates dust-
tight seal between top edge
of container and underside of
discharge hood. Second hydraulic
cylinder raises platform-hood
assembly vertically, before tipping it to a motion-dampened
stop at 60 degrees beyond horizontal, causing discharge
cone to mate with receiving vessel’s inlet port. Slide gate
valve prevents material flow until discharge cone is seated.
Convey fragile products gentlyover short or long distancesFLEXI-DISC™ Tubular Cable
Conveyors gently slide friable
bulk foods and non-foods
through smooth stainless steel
tubing using low-friction polymer
discs attached to stainless or
galvanized cable—driven by a
wheel at one end of the circuit,
and put under tension by a wheel
at the other end. Conveyor tubing
can be routed horizontally,
vertically or at any angle, through
small holes in walls or ceilings.
Single or multiple inlets and outlets can be added, removed or
relocated, and the circuit lengthened, shortened or re-routed
as needs change. Stand-alone units to automated systems
integrated with new or existing process equipment—to sanitary
or industrial standards.
Load/unload and condition bulkbags on all sides at all heightsBLOCK-BUSTER® Bulk Bag
Conditioner features a hydraulically
actuated, variable-height turntable
for automated in-frame bag
rotation and conditioning of bulk
bags at varying heights. The
number and pressure of hydraulic
ram actuations, the height of
the turntable, and the degree of
rotation are user-programmable.
Two hydraulic rams with specially
contoured conditioning plates
press opposing sides of bulk bags, loosening material that has
solidified during storage and shipment, enabling bulk bag
unloaders to discharge it through bag spouts. Cantilevered
I-beam with motorized hoist and trolley allows loading and
unloading of bulk bags without using a forklift.
Dispense and position pallets automaticallyFLEXICON® Pallet Dispenser
with Powered Roller Conveyor
automatically dispenses and
positions pallets, significantly
improving safety and efficiency
over manual methods. Accom-
modates 40 x 48 in. and 42 x
48 in. (102 x 122 cm and 107
x 122 cm) pallets and non-
standard sizes. Dispenser forks
lower the pallet stack onto the
roller conveyor, withdraw from
the bottom pallet, and raise the
remaining pallets, allowing the conveyor with photoelectric
sensors to position it. Audible signal and/or flashing light indicate
low pallet level. Easily integrated into palletizing/filling systems
for drums, pails, bulk bags, sacks and other containers/packages.
Unload bulk bags and rigidbins in low headroom areasFLEXICON® Low Profile Split
Frame Unloader allows discharg-
ing of bulk bags and rigid bins
from mezzanines and other low
headroom areas. Upper frame can
be forklifted onto plant floor, loaded
with a bulk bag, and then forklifted
back onto the sub frame within
several inches/centimeters of the
ceiling. A POWER-CINCHER® flow
control valve* cinches the bag
spout concentrically, preventing
uncontrolled bursts of material
from the bag, and allowing leak-free retying of partially empty bags.
For unloading of bulk solids from rigid bins, the bins are fork-
lifted onto receiving cups of the sub frame, and seated against
a flanged chute discharging into a vessel below the mezzanine.
As importantly, you will find experienced
process engineers who draw on Flexicon’s
20,000+ installations integrating conveyors,
screeners, grinders, crushers, blenders,
weigh hoppers, bulk bag unloaders/fillers,
bag/drum dump stations, and/or storage
vessels—experts who understand how your
upstream and downstream equipment can
impact, and be impacted by, the operation
of your pneumatic conveyor.
Going the extra distance to outperform
competitive pneumatic conveyors is what
the PNEUMATI-CON® advantage is all about.
It’s what enables Flexicon to guarantee top
results, and you to make pivotal improvements
to your process with absolute confidence.
