Overcoming the ObstaclesOvercoming the Obstacles
First was being able to consistently manufacture a media/feedstockseparation device with highly accurate fl ow thru zones that prevent escapeof the very small media (.3mm and below) from the mill while simultaneouslypermitting high volume passage of the feedstock. Additionally, the totalopen area must accommodate the rapid throughput from a hyperactivemedia fi eld without clogging.
Second was keeping the media in the grind chamber from escapingthrough the intake draft tube. Floatation as well as pressure increases inthe screen area can cause the media fi eld to expand into the void volumearea within the chamber and cause the media to escape through the upperintake draft tube.
Third was preventing media from leaking through the machined tolerancesbetween the bushing supporting the shaft and the shaft itself as it passesthrough the bottom screen of the mill chamber and connects to the suctionpropeller below it.
Fourth was substantially increasing the activity in the media fi eld to allowrapid feedstock pass-thru while simultaneously accelerating the number ofcontacts per unit of time.
Addressing the ChallengesAddressing the Challenges The Separation Device:The fi rst was overcome by the development of the *HOCKMEYER CONTAINMENT WALL* (multiple patents pending) consistent in open area size and with 43% porosity for feedstock fl ow. A technically improved and precise manufacturing process at Hockmeyer eliminated the use of typical screening devices using wedge wire or laser drilled openings which may only provide an open area of 10% or less.
The Intake Upper Draft Tube:Adding an auger to the upper draft tube of the mill chamber solved the second challenge. The auger plays several roles. The auger provides a consistent feed of material into the mill chamber during the startup process and prevents the media fi eld from fl oating during the initial immersion of the mill head into the batch.
Hockmeyer Announces Breakthroughs in Hockmeyer Announces Breakthroughs in NANO-MILL TechnologyNANO-MILL Technology
By: Herman Hockmeyer, Barry Cullens, Director of R&D and Process Applications, and Sidney Lowe, Applications/Design Engineer
THE HCPN IS A SPECIALLY DESIGNED MILL FOR GRINDING PARTICLES INTO THE NANO-PARTICLE RANGE WITH VERY SHORT PROCESS TIMES. THE NEW DESIGN INCORPORATES MANY DIFFERENT CHANGES IN THE INTERNAL MILLING SYSTEM WHILE LEAVING THE
FUNDAMENTAL, EASY TO CLEAN AND USE ASPECT OF THE IMMERSION MILL THE SAME.
The auger forces large agglomerates to stay in the milling chamber along with the media until they are small enough to pass through the screen. In this instance, the auger acts as a governor by allowing material in the upper draft tube to slip along the auger and not over pressurize the mill chamber. As a result of this governor affect, the media fi eld does not expand and media loss through the upper draft tube is eliminated. Depending upon its’ rheology, the feedstock fl oat may also be controlled through the size of the draft tube itself. The fl ow rate of oversized agglomerates is controlled by the pumping rate of the auger. The disintegration of the agglomerates is controlled by the intensity of the bead fi eld and the dwell time within the basket. Pumping rates can go up or down at any given speed by selection of the appropriately pitched auger. This allows for very high energy, hyperactive fl ow fi elds using very small media. Small media is considered to be at or below .3mm diameter.
The Support Bushing:The third obstacle was eliminated by the development of the HCPN centrifugal peg hub. The hub was designed to generate suffi cient centrifugal force to keep the media fi eld away from the support bushing in the bottom of the screen.
Increasing Media Oscillation Frequency:
As the size of media is reduced the number of contact points increases. The amount of void space between the beads becomes smaller, reducing the ability of agglomerates to “hide” between the contact points. However, this also results in fl ow fi eld lethargy. The bead fi eld begins to act more and more as a solid and becomes almost impenetrable by most slurries. The result is hydraulic packing and plugged screens. Fluidization of the bead fi eld increases the ability of the slurry to fl ow thru it. The higher the degree of fl uidization, the faster the slurry makes its pass thru the mill and returns for additional passes. The more passes made within a given time period, the faster the dispersion progresses. Hyperactivity of the media fi eld makes aggressive fl uidization possible. It is accomplished by dramatically increasing the number of contacts between the media and the feedstock per unit of time thus allowing rapid pass thru with high frequency contacts. Cascade Milling May No Longer Be Required : (In Some Instances) Hockmeyer developed a design that enables the HCPN mill to take a pre- dispersion to a nano dispersion without plugging the screen. The new HCPN has produced nano dispersions of Methol Violet, Rubine Red, Ultra Transparent Yellow press cake, Phthalo Blue press cake, Crude Blue and many other hard to disperse pigments straight from high speed disperser pre-mix to a nano dispersion in a very short time using .3mm media. No larger media pre-milling was necessary. The conventional wisdom of the need to use media 10 times larger than the largest agglomerate has gone the way of the buggy whip. The reason: Substantially higher power distribution to the bead fi eld, discussed in more detail further on in this paper.
These pigments in some cases, especially the yellow press cake, had agglomerates 1/2 inch in diameter when the milling started, and in a matter of two hours the entire particle size distribution was below the visible wavelength of light. Similar results were obtained in hard to grind solids such as alumina and steel when suspended in the
appropriate vehicle.
No Stagnation:When dealing with media small enough to produce a nano dispersion there were other issues in addition to containment that needed to be addressed. For example, the media in the mill chamber must not stagnate at any time in any area. Larger conventional media (above .3mm) is not usually a problem. However, smaller media presents many challenges. As media size decreases, hyperactivity of the fl ow fi eld becomes paramount.
Kinetic Energy Distribution in a Hyperactive Bead Field:As media gets smaller the mass of individual beads decreases. If the objective is to impact the agglomerates with
the same amount of energy generated by the larger media, an increase in velocity is necessary. The kinetic energy of a particle equals one half the particle’s mass times the square of its velocity. Beads are essentially spherical. The volume (and therefore the mass) of a sphere varies with the cube of its radius. So, a small bead ½ the radius of a larger bead will have 1/8th the mass of the larger bead. Because kinetic energy varies with the square of the velocity, the net result is the smaller bead will need 2.8 times the velocity to have the same kinetic energy as the larger bead.
The increase in velocity of individual beads is accomplished by increasing the speed of the impeller assembly. However, it is the counter-peg insert assembly that makes the higher impeller speeds functionally operative. Without it, the higher speeds would merely create centrifuging of the bead fi eld with little effect on milling performance. The combination of these two improvements simultaneously increases fl ow fi eld activity, bringing it toward the hyperactivity range; the higher the speed, the greater the number of contacts per unit of time and the greater the feedstock throughput.
As the media size decreases the peg tip speed increases to compensate for the loss of mass of the individual beads. Although higher speeds are required to compensate for the reduced mass of small beads, the particles being ground are also smaller, so the kinetic energy per bead does not have to match that of large media.
The net effect is still a higher amount of horsepower per liter of small beads compared to an equal volume of larger beads. Although as beads decrease in size they will continue to break down smaller particles using proportionally less power per bead, the number of beads per liter increases dramatically. The increase in horsepower/liter of beads will manifest itself in higher heat in the bead/slurry fi eld. It will also reduce the amount of time required to reach a given standard, assuming temperature can be controlled within the tolerance range of the slurry. The design of the HCPN mill creates a more uniform power distribution to the bead fi eld thus allowing more power per bead without the heat and wear problems associated with hydraulic packing.
The following is an example based upon power input being equal to power output. Theoretically, to arrive at the same power input/bead on the smaller beads, the horsepower input per liter of beads would have to increase by a multiple commensurate with 2.8 times the velocity increase. However, as the relative mass between the bead and the agglomerate decreases, so does the average power input required per bead to break the smaller agglomerates. Although higher peg tip speeds will clearly require more horsepower (holding bead density as a constant), a number of variables will affect the actual power needed to grind a particular product. These variables include feedstock viscosity, rheology and specifi c gravity, as well as bead size, density and the types of impellers used to generate fl ow into and out of the mill. As a general statement, based on Hockmeyer’s laboratory tests to date, a nano immersion mill with small ( at or below .3mm ) media operating at higher peg speeds may require a multiple of as much as two or more times the horsepower of a conventional counter peg mill using large (.8mm and above) media operating at lower peg speeds. What diminishes ongoing de-agglomeration is the reduction in fl ow fi eld activity as well as the point of diminishing effectiveness of the bead size compared to the particle size. When using very small media, much higher levels of media activity are required to prevent momentary stagnation of the slurry within the fl ow fi eld and continue the de-agglomeration process. Without this hyperactivity, the process will slow dramatically and further improvement becomes long and arduous. The additional power input via higher peg speeds and increased peg count is required to maintain the hyperactivity in what would otherwise become a lethargic and highly obstructed fl ow fi eld with little or no throughput of the feedstock in conjunction with rapid temperature rise of the feedstock.
Once the smaller beads have reached equilibrium with the feedstock where the beads are approximately 1,000 times larger than the particles of the feedstock, further particle size reduction will slow to its least effi cient level. To continue the particle size reduction smaller media is required. However, our testing of higher peg speeds without changing media size has shown signifi cantly improved performance extending to smaller particle sizes than those generated by the traditionally lower peg speeds. The price for this approach is higher wear to the internal components of the mill.
If bead diameter remains the same but kinetic energy is increased through peg speed, the resulting higher oscillation frequency causes the dispersion to progress further. More frequent collisions coupled with higher relative power/bead compensate for not reducing bead size. Although higher frequency and throughput are of
great value, they are not a panacea and will reach a point where bead size must again be reduced for further improvement of the dispersion.
Earlier in this paper a comment was made on how the traditional recommendation of bead diameter to agglomerate diameter ratio of 10 to 1 can be inverted using new technology. Raising and distributing the input horsepower per liter of beads made the process work because of the proportional increase in the amount of energy put into each bead. Without this power distribution addition, inversion of the ratio would not have been possible and the beads would have been unable to overcome the much larger mass they were attacking.
Heat Generation and Removal: As the delivered HP/Liter of media increases while the slurry volume remains constant, heat generation increases, becoming yet another obstacle requiring resolution.
Hockmeyer designed a highly effi cient heat transfer device for cooling, positioned just below the lower discharge draft tube of the Immersion Mill. Chilled water fl ows through the device as the bottom propeller surrounded by the lower discharge tube of the mill blows the slurry discharge against, through and around it.
Tests have demonstrated the system’s ability to maintain a temperature of 100 F while the HCPN-1 Immersion Mill was pulling full 10 horsepower in one liter of .3mm ceramic media at elevated peg speeds. The combination of the jacketed tank, the cooled rack dome and the cooling coil, enabled the chiller to remove the heat generated by an introduction of a measured 10 horsepower into the 1-liter media fi eld operating in a 5-gallon batch of pigment dispersion continuously over a 2-hour time period.
Batch Turnover:Horizontal mill manufacturers typically consider recirculation milling as an increase in throughput that results in about 12 to 16 theoretical turnovers of the batch, occurring over a period of hours. The Immersion Mill can turn the batch over as many as 12 to 16 times per minute and thousands of times during the batch cycle, depending upon the feedstock and its’ cycle time. This produces tighter particle distribution bands and improved qualitative aspects such as color development, transparency, gloss, etc. Utilizing this type of performance from the standard Immersion Mill and coupling it with the ability to run very small media and eliminate cascade milling in many instances, the HCPN has proven to be a substantial step forward in processing technology.
SummationSummationNano milling is becoming more and more practical as we learn the idiosyncrasies and demands of the process. The ability to effi ciently use smaller and smaller media is an important part of this technology. Equally important, however, are the discoveries of effective media/feedstock separation techniques, the generation of intense and rapidenergy exchange between media and feedstock, and the aggressive control of temperature. Understanding and controlling what is actually happening as we engage this frontier is a challenge we continue to embrace and make a reality.

SINGLE SHAFT DISPERSERS
A disperser is a type of mixer used to rapidly break apart lumps of powdery material, uniformly distributing and wetting them in a liquid. It is also used to dissolve soluble solids in liquid.
Dispersers are available with single speed, two speed and variable speed mixing shafts. Some are directly mounted atop a tank and are fi xed to operate with the blade in only the original mounting position. Other tank mounted dispersers can raise and lower the blade by several feet (to better control the vortex) without exiting the tank. Another design, perhaps the most popular, places the disperser on top of a hydraulic lift that is mounted to the fl oor. The lift enables the opera-tor to raise the blade completely out of the mixing vessel and change to another vessel. This technique uses small portable tanks (up to 500 gallons) that can be rolled away on wheels or picked up with a fork truck. Larger stationary tanks are oftencentered within the arc of rotation from the center of the hoist to the center of the mixing shaft. The bridge containing the mixing shaft at one end and the motor at the other is then rotated from one tank to the next. Choosing the best confi guration of available designs is a combination of functional need and economic justifi cation. An experienced process engineer or consultant familiar with dis-persers is a good investment.

High shear disperser blades are available in a range of styles and sizes. They can be generally categorized into two groups, open saw tooth and ring type. Both categories work well when used under the proper operating conditions.
The open saw tooth blade is the most popular because of its low cost, ease of cleaning, and general utility. It is available in a wide range of tooth designs. As the teeth increase in size and become more aggressive in shape, the pumping ability of the blade increases. However, as pumping (turbulent fl ow) increases, shear decreases. A high pumping saw blade still generates signifi cant shear compared to a low shear paddle blade agitator. This aspect is an important consideration when determining exactly what is to be achieved in the fi nished product.
The ring type blade is a powerful tool for optimizing disperser performance. It typically runs at higher tip speeds (5700 + fpm) and performs more like a rotor stator. Instead of depending solely upon the face of the disc and the confi guration of the saw-tooth for shear and fl ow, much of the ring blade’s work is done hydraulically as centrifugal force forces the product between the contoured rings creating velocity differentials and a high pressure zone within and then instantaneously discharging into the low pressure area outside the rings, creating a fi lm splitting venturi effect. Additional heat is created as a by-product of the higher shear. However, in some cases, this higher shear level eliminates or greatly reduces any subsequent milling that may have previously been required.
A Chassis Variable Frequency Drive (VFD) can be provided as the standard or can be provided as a Built Up pre-wired unit complete with a fused main input disconnect to meet electri-cal code requirements. This eliminates the need to purchase a separate input disconnect, reducing installation time and cost. The VFD is pre-programmed and tested with the machine.

MULTI- SHAFT MIXERS DUAL & TRIPLE SHAFT MACHINES
HOCKMEYER’s Multi-Shaft Mixers have a center mounted low speed Helical or Anchor Sweep blade sweeping the mixing vessel wall and an additional high speed shaft(s). The high speed blade typically provides high shear to disperse or dissolve ingre-dients. The low speed blade feeds the high speed blade by blending and folding the mass in the ves-sel and improves product uniformity by scraping the walls. Multishaft mixers are most often used to mix medium to high viscosity products. A high speed disperser alone has a limited zone of infl u-ence in viscous products, so the low speed blade is necessary to achieve a homogeneous mixture. When equipped with scrapers (as is typical), the low speed blade also aids in heat transfer to an external jacket. Multishaft mixers are sometimes used with low viscosity products when scraping the vessel wall is benefi cial.

The HOCKMEYER Difference . . . Our multishaft mixers are designed by an experienced engineering staff incorporat-ing information from customers, our own R&D Laboratory and data from decades of HOCKMEYER Multishaft mixers in service. Our standard low speed blades, for example, use a triangular cross section, which is both strong and presents a wide profi le for effi cient mixing action. This design is stronger than a blade made from fl at bar and easier to clean than a blade with circular structural elements. Our low speed blades move product effi ciently at relatively low peripheral speeds, and typically require less horsepower than our competition’s mixers. Lower tip speeds mean longer life for scrapers. HOCKMEYER machines have a reputation for performance and reliability. That is by design.
Applications: Used in the making of printing inks, sealants, caulks, hot melt adhesives, magnetic media slurry, creams, lotions, toothpastes, etc.
Triple Shaft Mixer with Rotor Stator
The Triple Shaft Mixer features three indepen-
dent impellers which achieve high perfor-
mance mixing action.
The low speed sweep blade is in combination
with two other impellers. Choose from two dis-
perser blades, axial fl ow agitator, gate blade or
auger screw for optimum performance.
Viscosity capabilities range up to 2 million
centipoise. A hydraulic press is available to oper-ate with dual and triple shaft mixers.
The unit optimizes production ef-fi ciency, is made of heavy duty con-
struction and is self-cleaning.
HOCKMEYER’s Multi Tasking System (“MTS”)Streamline your process – Same Tank – Same Place – From Start to Finish
With the introduction of our HSD Immersion Mill into our multishaft mixer, we have created what is unmatched by any other! We call it our Multi Tasking System or “MTS.” This unit is essentially a “one step processing” machine, meaning you do your Dispersion, Milling and Deaeration process all within one machine. The MTS consists of two or three shafts, a High Speed Shaft and Blade, our patented HSD Immersion Mill and a Low Speed Shaft with either a Helical or Sweep Blade - depending on the viscosity of the product being processed.
In considerably less time, the MTS can process liquid dispersions and paste type dispersions that are typically run on a 3-roll mill.
As shown below, the MTS can be customized to meet your process requirements.

HOCKMEYER’s Gate Blade Double Planetary Mixer incorporates close paddle blade-to-tank tolerances to assure thorough mixing of high solids and high viscosity materials. The intersecting Gate Blades come to within 3/32” of the sidewall and bottom of the vessel, ensuring that every part of a viscous product is thoroughly mixed.
HOCKMEYER has developed a high performance Planetary Helix for our Double Planetary Mixers. Un-like conventional helical tines, the Planetary Helix has a variable pitch. Starting at the top of the helix, the pitch of the tine decreases, as it extends deeper into the batch. As a result, each tine is longer and extends beyond the curvature which allows it to move more material both vertically and orbitally.
HOCKMEYER’s Horizontal Paste Mixer is a rugged mixer for effi cient, fast handling of heavy, large volumes of highly viscous, non-fl owable materials. This mixer features triple mixing blades for uniform wetting and fast mixing, as well as a specially designed impeller that follows the contours of the tank precisely. This helps eliminate “dead” spots. In addition, the overlapping arms prevent material buildup while the double rolling action of the blades kneads and rubs the material against the side of the tank for excel-lent shear and wetting. Even the toughest materials are quickly transformed into a homogeneous mass, and since there’s no wasted motion during the thorough blending process, this mixer requires less power than similarly sized machines.
APPLICATIONS: The Horizontal Paste Mixer is ideal for adhesives, caulks, sealants, automotive body fi ller, textured coatings, printing inks, polyesters, ceramics, cosmetics, pharmaceuticals, etc.
