around moving parts at the factory are

meant to prevent accidental injury to

operators and other personnel. Do notremove them.

Note: Guards are shipped loose and need

to be installed by the customer.

Management ResponsibilitiesMake sure that everyone working on or

near this equipment is familiar with safety

precautions. Have a supervisor at the job

site who is responsible for job safety give

the crew members specific safety

responsibilities and instruct them to report

any unsafe conditions to their supervisor.

Operator ResponsibilitiesRead all danger, warning, caution, andnotice signs. Always lock out and tag out

equipment upstream and downstream

before performing maintenance activities

or adjustments. Make it impossible for

anyone to start this machine while others

are working on it or in it.

Never remove any guard, cover, or shield

when this equipment is in motion.

Replace guards, covers and shields whenthe task for which you removed them is

finished. Block parts as necessary to

prevent their sudden movement while

people are working on the machine.

Never attempt to clear away jammed feed

material, discharge material, or other

stoppage while the machine is running.

Stop the equipment, lock out and tag out

before touching this machine with yourtools or your hands.

Wear proper personal protective

equipment, including eye protection,

hearing protection, hard hat, safety

glasses and safety shoes, whenever

youre near this machine while it is

Page 3-1 Set UpScreens

Section 3 - Set UpRefer to your site plan or contact your

Terex Simplicity distributor for guidance in

determining the best location and required

clearances for the machine and related

equipment.

Receive and Inspect the Plant

Make sure the Machine Start-Up

Report & the Delivery InspectionForm (located in the front of this

manual) is completed, signed, andreturned in order to initiate theTerex Simplicity warranty period.Usually, your service representativefills out the form and you completethe bottom of the second page.

When the machine is delivered, thoroughly

check for any damage that might have

occurred during transport. Do not move the

unit until the inspection is complete.

Write down any damage on the shippers

bill of lading and have the truck driver

initial your description of the problem(s).

Keep a copy of the marked-up bill of

lading for your files. Take photos, if

possible. A photo record of any damage

will be important if there is any challenge to

your claim.

File a damage claim form with the carrier

within 30 days of receipt of the equipment.

Check loose parts, small-parts boxes, and

tools against the packing list to make sure

that all items are included.

Do not use any part of the shaft

assembly when lifting your screen.

HandlingYour Terex Simplicity Screen will have

lifting holes at each corner support bracket

for lifting the machine. Cable suspended

units use the suspension bracket for lifting.

Use chains or cables of sufficient length

so that strain is not applied to the sideplates. If short chains are used, then aspreader beam must be used to prevent

damage to the side plates. See Figure 3-1,below.Remember that your sling capacitydecreases as the angle of lifting

decreases. Lifting devices must be used

according to proper commercial practice.Refer to the bill of lading or specification

for the weight of your vibrating screen to

make sure you do not exceed the lifting

capacity of your equipment.

StorageIf you do not plan to install and put into

operation within two to three weeks after

receiving, take the procedures indicated

below to insure safe storage of the screen.

1. Place the screen in a building which

has a constant temperature and arelatively low humidity.

2. If open storage is required, the

following steps are necessary to

protect the screen from corrosion due

to moisture condensation:

PlanningYour Terex Simplicity Screen can be

purchased to be installed on a sub-

structure, supported from overhead by

cables, or a combination of these

methods.

1. The standard Screen is supplied with

springs and spring base plates only.

A support structure must be furnished

along with a support for the motor

base.

2. A catwalk or service platform should

be provided on both sides of the

screen for observation and servicing.3. If you plan to overhaul the assembly

in place, provision on one side of the

screen should be made for the

eccentric shaft removal. This

generally should be the width of the

screen, plus approximately three (3)

feet.

4. Overhead lifting provision should be

made for repair.

5. Plan necessary feeding devices,

spray pipes, collection hoppers or

chutes simultaneously with the

screen installation. Allow for

adjustment and removal of these for

service on the screen. (See notice at

top of next column)

To remove the support springs,

enough clearance must be providedto raise the screen to clear the

spring pilots, (approximately 6" 8"). We suggest putting a 6" high,bolt in spacer or raiser block underthe coil spring base plate. If this isdone, coil spring replacement ismuch easier.

6. On Oscillating Screens, the drive

mechanism may have to be removedfor repairs. Proper provisions should

be made for removal of the drive.

7. Allow room for deck removal, which

generally can be provided at the

discharge end by removing

discharge chutes. However, the

decks can be removed from either

end.

8. An adequate power source and water,

if required, should be available.

9. Install and connect all electrical

components and motors according to

local electrical codes.


28/64


2.1 Cover the screen cloth to prevent

damage. It may be advantageous

to cover the entire screen.

2.2 Paint any bare metal or scratches.2.3 On grease lubricated shaft

assemblies, periodically pump

recommended grease into bearing

housing while rotating by hand.

Before putting screen into operation

after extended storage, flush

bearing with warm oil and re-

grease with recommended

lubricant.

2.4 On oil-bath shaft assemblies, forlong-term storage greater than 30

days, it is recommended to use a

corrosion inhibitor mixed with the

oil. Corrosion inhibitor is used to

protect the internal drive parts

thereby minimizing the damage

from corrosion, which will lead to

premature bearing failure.

Breathers must be replaced with

solid pipe plugs after the

inhibitor is added.The inhibitorprotection is good for one year. Two

other methods are as follows:

A. On horizontal units with oil sight

gauges, the oil should be half

way on the sight glass when unit

is setting flat. Periodically rotate

the assembly by hand to re-

lubricate the bearing rollers. Be

sure the unit is setting level from

side to side to insure that the oil

level is the same on both sides. If

setting out of level, the oil could

run to the low side and uncover

the high-bearing rollers.

On Simpli-Flo units the oil will not be

half way on the sight glass whensetting on the ground or on truck duringtransport. If the breather is in the feedend drive, oil will leak out.

B. Fill the assembly completely full of

oil, including the center shaft

housing, even if the drive

assembly has oil in the covers

only. After storage, drain the oil

and replace with proper oil before

putting the screen back intooperation. (See Lubrication

Section in Section 4, for proper oil

selection)

2.5 If the storage area is subject to

vibration, care should be taken to

isolate the screen.

2.6 Take corrective action if there is

any indication of rust or corrosion.

2.7 On Four-Bearing units, block the

vibrating frame to relieve the load on

the main bearing and/or rubber-in-

shear mounts.

Storage After OperationUse the same instructions for the assembly

as stated in the above, with the following

procedures:

1. Lockout and tag out the machine.

2. Relieve the tension on the v-belts by

blocking the pivot motor base up.

Place paper between the belts andsheaves. This will prevent sticking.


29/64


Two or more units running at the same

speed setting side by side in the samestructure can become synchronizedand will cause excess vibration in thestructure.

Cable SuspensionA suspended Screen has four mounting

brackets located near the top edge of the

screen side plates. The suspension parts

consists of the following: cable,

compression springs, top and bottom

mounting plates, suspension rod, cablethimbles, cable clamps and cable weights.

When a machine is cable suspended,auxiliary safety cables and electricallyinterlocked failure switches are

recommended for safety of personnelworking in the area.

The proper cable and springs are supplied

with your suspension parts, but due to

other contributing factors, you should

compute the allowable cable loads, taking

the following into consideration:

1. The actual weight of the vibrating

screen, including all the auxiliary

equipment that may be attached to

the screen.

2. Material loads on all screening

surfaces are assumed to be six

inches (6") deep.

3. Add 40% to the above totals to take

care of any external impact load,

change in screen weight, overloads

and dynamic load at stopping.

Support Structure DesignTo insure safe screen operation, all

installation and support structure designs

should be prepared and approved by

qualified engineers.

Floor MountedThe design of the support structure

requires:

1. The angle of recommended setting.

See installation drawing fordimensions.An adjustment of +/- 3

degrees should be considered in yourdesign.

2. The structure to be strong enough to

support the static and dynamic load

at stopping. Refer to data oninstallation drawing.

3. The natural frequency of the support

structure to be above the screen

running speed by a factor of 2-1/2

times.

4. The structure must be braced to

minimize vibration.Excessive vibrationin a screen support system wastes

energy and causes a serious loss of

screening efficiency. If possible,

support screen base frame directly

below support springs (Figure 2).

Figure 3-2 - Support Structure


30/64


The maximum allowable load for one

suspension cable is indicated below:

1/2" diameter = 3500#

5/8" diameter = 5000#

3/4" diameter = 8000#

General information on cable suspension

arrangements are shown in Figure 3-3,

below.

The following items should be checked

when using cable suspension:

1. Wire rope and fittings must be

assembled according to proper

commercial practices.2. The support points for cables must be

located so that the cables are vertical

or at a slight angle when the screen is

in operating position.

Figure 3-3 - Cable Suspended Inclined Screen

3. Ample clearance around the

suspension rod must be allowed to

prevent wear.

4. The feed end cable should have a

minimum of four feet (4) between

support eyes. Long cables tend to

whip on vibrating screens and cause

failures. To correct this, weights may

be attached to the cable. The location

of the weights varies. You should start

at the midpoint, moving the weight up

or down, and determine by trial and

error the best location. Replace any

frayed cables.5. Tag lines may be required to maintain

the screen in proper location with the

drive and chutes. A tension spring and

cable arrangement, to be supplied by

the customer, should be used.

Figure 3-4 - Incline Screen

InclinationIf youve purchased an Inclined Terex

Simplicity Screen, it depends on

gravitational force to assist in propulsion

of the material. Therefore, the screen must

set at an angle for good screening. The

inclination is determinded from the

installation drawing provided. It normally

ranges from 15 and 25 degrees. The

optimum slope for any particular operation

is where the greatest volume of oversize

material can be handled and still remove

the available undersize to meet required

standards. Consult the factory beforechanging the angle of inclination.

The recommended angle of operation is

given in the specifications and is based on

general material characteristics and screen

ability. Your product and specification may

not fit into this category so a built-in

Installing the ScreenCheck the total weight of your screen to

insure you do not exceed the lifting capacity

of your equipment. Do not use any part of

the shaft assembly for lifting. The screen

support structure should be completed per

the instructions on planning the installation,

as previously discussed in this manual.

Your Terex Simplicity Screen has lifting

holes in the corner support brackets. Use

cable or chains of different lengths, with

the shorter ones on the feed end, to lift the

screen at the approximate angle the screen

should operate. This angle is shown on the

installation drawing.

This operating angle may be gauged when

lifting by looking at the discharge end of the

side plate which will be close to

perpendicular to the ground. Do not use

this as a check gauge when mounting thescreen. This operating angle should be

checked on the top deck. Care should be

taken not to damage the side plates. A

spreader beam may be required to hold the

cable or chains away from the side plate.

Set the support springs at the four corners

on the base plates guides. Lower the

screen carefully onto the springs, making

sure all pilots engage the springs beforethe full weight of the screen is allowed on

the springs. If a spring has not engaged

properly, adjust it with a nylon hammer or

pry bar.

Do not use your hands to adjust springs.Do not disconnect the lifting cables until

all springs have been checked for

alignment.

Check the screen after installation across

the width at both ends to make sure that itis level. Add shims as necessary to level

the machine. An out of level machine

will cause material to travel to the low side

of the machine and can create stresses in

the body of the screen, which could leadto catastrophic failure.

When mounting a cable suspended screen,

the suspension cables should be made up

and attached to the suspension brackets on

each corner of the screen. The excesscable should be laid on the screen deck.

The unit must be level across the width on

both ends when in operating position.

adjustment of +/- 3 degrees in the design of

your support structure, feed, and discharge

chutes would be to your advantage.

In most good screening applications, 75%

of the undersize material passes in the first

25% of the screen deck.

The bed depth should be kept to a

maximum of four (4) times the screen cloth

opening. Also, note that the increase in

inclination decreases the effective screen

cloth opening, which results in a finer

separation. It may be necessary to

increase the screen cloth opening size.


35/64


Direction of RotationSome Terex Simplicity Screens can

rotate in either direction, with or against the

flow. Rotation with the flow of material is

used when a large volume of material and a

high percentage of oversize material are

being handled. The efficiency of thescreen may be lower with the flow of

rotation. Counter flow rotation usually

gives more efficient screening but less

volume.

The motor base is located to operate with

the flow. If counter flow operation is

required, then the snubber spring must be

tighter to restrict the motor at starting.

V-belt DriveMost Terex Simplicity Screens come with

a pivot-type motor base. This base must

be mounted on a support structure. Seeyour installation drawing for location.

The motor center is mounted approximately

1-1/2" to 2" behind the motor base pivot

shaft toward the springs. This usually

provides enough counterweight to keep the

v-belts at proper tension.

A properly mounted motor should be

horizontal. The springs provided are

snubber springs to restrict the motor from

going past center when the screen stops.

These springs should be compressed just

enough so they dont rattle. There are four

(4) heavy-duty flat washers mounted on top

of the springs. These washers aremounted here for shipping only andshould be removed and used on the

foundation bolts as shown in figure 3-7.

The machine and motor sheaves supplied

with your screen are special deep-groove

sheaves. The belt size is indicated on yourcertified drawing. If a different motor

sheave is required for a speed change, the

sheave should be ordered from your dealer

or the factory. Standard sheaves of the next

larger belt size will not line up properly.

Water Cooled Shaft AssembliesIn an extremely hot atmosphere, a water-cooled assembly may be required to cool

the bearings. This is an option that should

be ordered with the screen. However, this

option is not available on all models.

Check with us for availability.

Do not change speed of unit without

first contacting factory engineers.

The belt guard supplied will have to be

supported on the same plane as the motor

base. Care should be taken to allow

enough clearance around the guard when

the machine starts and stops.

The v-belt size is shown on your certified

drawing. The drive components, belt

guard, machine and motor sheave are

designed to use this belt size, so check thebelt size against the size shown on the

drawing.

These are two methods that we use for

water cooling:

1. The end castings on the shaft housing

have a water passage. These

castings are drilled and tapped with

pipe threads and are furnished with

pipe plugs. Each side must be

hooked up to a water supply and a

drain.

2. Assemblies with oil lubrication will

have a complete jacket around the

shaft housing. There is an inlet and

outlet pipe flange on each end of the

housing water supply and drain to beattached with flexible lines to one

side only. The opposite side to be

plugged with pipe plugs.

3. Use only clean water to cool the shaft

assembly at a rate of 3 to 5 gallons

per minute.

4. The heat exchanger (water cooled

shaft housing or end castings) should

be flushed thoroughly each time

assembly is overhauled or at least

once every 10-12 months. Restrictionin water flow rate will aversely affect

bearing life.

The lines should be drained to prevent

freezing when shut down during cold

weather. You should never put a shut

off valve in the drain line. If steam

pressure is allowed to build up, it could

cause serious damage to the weldment.

Material Feed ProcessThe most important part of your screen

installation is the feeding arrangement. In

order to efficiently utilize the screen

capacity and minimize screen cloth

maintenance, the following steps should

be reviewed:

1. The material should enter the feed

area along a line parallel to the

center line of the screen. A 90

feeding arrangement should be

avoided.

2. Feed the material at a uniform rate

with even distribution across the

width of the screen.

3. Conveyors or other feeding devices

should not feed directly onto the

screen cloth. A stationary feed box orother retarding method is needed to

slow the material as it enters the

screen. Refer to Figure 3-8 below.

Keep in mind the material size and

drop distance when setting up the

feed arrangement.

4. Chutes or non-vibrating feed boxes

distributing the material to the screen

should be at least six (6) inches

narrower than the deck.5. The feeding device should be about 3-

5, depending on the size of screen.

See installation drawing for

recomendations. An optional

vibrating feed box is available.

Figure 3-8 - Feed Box


37/64


Spray Pipes & Wet ScreeningThere are two types of spray pipe

arrangements, vibrating and non-vibrating.

If non-vibrating spray pipe arrangement is

used, the hole in your side plate must be

larger. Whichever type of spray system

used, you must be sure the drive assembly

can be easily worked on. This could

possibly mean removal of the spray pipe

manifold. The spray pipe hoses on the

vibrating type must have enough extra

length to them so they do not restrict thestarting and stopping of the unit.

Do not burn holes in the side plates to

provide openings for spray pipes. Torch cut

holes induce stresses in the area around

the hole, which could lead to cracking of the

side plate. If the spray bar holes are not

ordered with the unit, use a hole saw to cut

these openings and dress the edges.

On wet screening the material may come to

the screen in a slurry or dry form. Pre-wetting of dry material may be required,

which can be accomplished in a stationary

feed box.

Under no circumstances shouldadditional components be added to thevibrating body without approval ofTerex Simplicity.

Discharge ChutesThe chutes handling the oversize material

must have sufficient slope to prevent

material hang-up. This is usually 60 from

the horizontal. Enclosed chutes musthave a minimum depth of four (4) times the

maximum particle size. Provision in your

design should be made for easy access to

the screen cloth for removal. These could

be hinged or easily lifted away.

Fines HoppersA fines hopper collects the through-

product of the bottom deck. The design of

this hopper should be such that materialwill not collect in the valleys and build up,

thus interfering with the screen. This

valley angle is usually a minimum of 45.

An access should be provided for

entrance into the hopper and to the

underside of the screen. Fines build up will

need to be cleared out everyday when

operating in temperatures below 32F.

WalkwaysWalkways should be provided so your

operators can observe the performance of

the vibrating screen. These walkways

should be designed as work platforms to

be used to perform routine maintenance,

change screen cloth, and to repair the

assembly. Repairs will be made lesscostly if access is convenient.

Chutes & HoppersWhen designing the feed chutes and/or

boxes, discharge chutes, fines hopper,

any dust enclosure, you must allow a

three to five inch (3-5) minimum clearance

for the exaggerated motion when starting

and stopping. The screen body must nottouch any stationary object under any

circumstance. This includes any possibleaccumulation of material in the corners of

the fines hoppers or in a product chute.


38/64


Further washing or rinsing is usually done

with spray bars. The sprays are generally

directed against the flow of material at an

angle up to approximately 45. However,the spray nozzles are adjustable and should

be adjusted so the spray does not stop the

flow of material and to give you the best

cleaning action. The number, size and

spacing is dependent on type of material,

material feed and water available. As a

rule of thumb guide, 3-5 G.P.M. of water on

the screen, for every ton per hour of feed is

sufficient. The water should be on the high

side if clay is present.

The water spray should be adjusted so

it is not spraying directly on pipecrossmember in the deck.

Keep in mind when determining the water

requirements that it is easier to valve down

than to find additional water capacity. The

water pressure should be determined at thenozzle rather than at the pump (usually

around 30-35 psi.

Screen Cloth TensionThe tensioning of the screen cloth is very

important. Improper screen cloth tension

will cause premature failure and decrease

screen efficiency. If the cloth sags, or the

material boils, the screen cloth is loose

and has to be re-tensioned.

The screen tensioning method consists of

take-up rails with carriage bolts or wedge

assemblies. See Figure 3-9 .

Adjust new screen cloth after the firstfour (4) hours of operation as thescreen tends to stretch.

Follow the steps below when adjusting

screen tension:

1. Lock & Tag out machinery and make

sure the screen cloth is clear.

2. Loosen the take-up rail nuts/wedges

to assure that they are not frozen and

that correct tension can be attained.3. Tighten the take-up nuts/wedges

equally from side to side until the

screen cloth is Drum Head tight. Be

sure not to over tighten the cloth

causing a tear. Tightening screen

cloth is an art more than a science,

and when tension is correct, the cloth

will have no sags. There should be

clearance between the screen side

plate and the screen cloth hook stripsto insure proper tension.

Figure 3-10 - Motor Base Adjustment

Motor AdjustmentRefer to Figure 3-10 below.

1. Lock & Tag out machinery2. Remove belt guard.

3. Loosen the four (4) mounting bolts

(Z), (AA), (BB) and the two (2) rear

adjusting set screws (S).

4. Tighten the two (2) front adjusting set

screws (S), and slide the motor further

past the base center line. This

adjustment should be made in 1/4"

increments 1-1/2" to 2" from center

line to center line.

5. Tighten the two (2) mounting bolts (Z),(AA), (BB) and check the belt tension.

You may have to start the screen. If

the belt tension is correct, tighten the

remaining two (2) mounting bolts (Z),

(AA), (BB).

6. Tighten the two (2) rear adjusting set

screws (S). These set screws act as

locking bolts also.

7. Replace belt guard.

Extreme care should be used when

operating screen without belt guardfor test.

Base Adjustment1. Loosen the four (4) foundation bolts

(X), (Y) on the bottom legs (K) of base.

2. Using a pry-bar, jack, or come-a-long,

slide motor and base until motor is

horizontal.

3. Leaving pressure on the base, tighten

the four (4) foundation bolts (X), (Y).

4. Check clearance on belt guard and

adjust if required.


40/64


V-belt Adjustment w/Fixed BaseThe V-belt should have enough tension to

prevent slipping. New V-belts should be re-

tensioned after 24 to 48 hours of operation.

Slipping belts cause excessive wear on the

belts and sheaves. The following is the

acceptable method for checking belt

tension.

1.) Refer to Figure 3-4 below, measure

the span of the unsupported belt in

inches. This span is approximately the

drive center spacing (D).

2.) Determine the designed deflection

which is an amount equal to 1/64 ofeach inch of span length. For

example: the deflection for a span of

36 would be 36/64 or 9/16.

3.) Using a spring scale and steel tape,

apply enough force at mid-span to

deflect the belt the desired amount.

Note this force and compare it with thevalues in the table below (Figure 3-

11). If the force is between the normal

tension (Column A) and maximum

tension (Column B), the drive tension

should be satisfactory. A new belt or

belt set should be tightened to 1.5

times normal tension.

before adjusting stroke, motor speed, ortiming.

Oil Sight Gauge AdjustmentIf you have a Simpli-flo Screen, the oil sight

gauge was adjusted for the angle of

inclination that the screen will operate. If

the inclination is changed or the gauge

moved in shipment, the gauge must be re-

calibrated. The following steps are

required. Refer to Figure 3-12.1. Check on the bottom of the shaft

housing to make sure the unit is level

from side to side.

2. Remove the 1/4" oil check plug, float

side or the side with the oil level

gauge. Pipe plug is at the bottom of

the outer seal retainer.

3. Add proper lubrication oil at breather

on the drive side. Allow time for the oil

to travel the width of the screen andrun out the 1/4" check plug. Allow the

oil to slow to a drip.

4. Replace 1/4" check plug and breather.

Oil level should be half way or center

line sight gauge.

5. If sight gauge needs to be adjusted,

loosen 1/2" bolt and nut securing sight

gauge mount block.

6. Slide sight glass mount up or downuntil oil level appears in center of

glass.

7. Tighten 1/2" bolt and nut.

8. Loosen 1/2" oil drain plug and allow

hose to drain for a moment than re-

tighten 1/2" plugs.

9. Check oil level in the sight gauge.

NOTE: If there is not enough adjustment in

the mounting angle for proper oil level, thensight glass adjustment angle must be

relocated.

Daily Maintenance1. Check the oil level and check for any

oil leaks.

2. Check the screen body for material

build-up and screen cloth for blinding.

3. Check the screen cloth for wear and

proper tension.4. Make sure that there is 3 to 5

clearance between the vibrating body

and any stationary object such as

material build-up in hoppers, chutes,

etc.

5. Check all bolts for tightness.

6 . Lubricate all bearings that require

grease lubrication.

7. When the screen is operating, listen

for any unusual noises that may

indicate loose bolts or loose or

damaged moving parts. It may also

mean the vibrating body is running too

close to a stationary member.


43/64


44/64


Flushing procedureFill the mechanism to the proper level with

light EP oil and run the machine for

approximately fifteen (15) minutes.

Immediately drain the oil out of the machine

upon shutdown. This will pick up additional

contaminants that otherwise would have

remained in the system.

Your machine was shipped with break-

in oil, therefore, you should change theoil after the first forty (40) hours of

operation. This procedure should also

be followed if the machine has been

setting idle for an extended period of

time.

Regular lubricant changes should be

scheduled for every 300 to 500 hours of

operation or every thirty (30) days,

whichever comes first. This regular change

will rid the mechanism of any condensation

or contaminants that would cause troublelater.

The oil should be drained immediately upon

shutdown so any contaminants are still

suspended and will easily flush out.

If, when draining the oil, contaminants are

noticed, it is highly recommended that you

also flush the mechanism with a light EP oil

(EP-2 or EP-3).

Synthetic OilsSynthetic oil provides superior bearing life

over a wider operating temperature range

than their petroleum counterparts. TerexSimplicity recommends using the synthetic

Mobil products listed below in Figure 4-1,

or their equivalent. If a synthetic oil doesnt

fit your requirements, see the next page for

the proper ISO selection table (Figure 4-2).

Selecting an Oil LubricantSome guidelines that should be used in

selecting an oil lubricant are as follows:

1. The oil should be a high quality, non-

oxidizing petroleum product.

2. The viscosity of the oil should not be

less that 105 SSU at the operating

temperatures.

3. The oil should have a Timken OK load

rating of 50 or more.

4. Oils containing viscosity index

improvers should not be used. (No

multiple viscosity)

5. Oils should have extreme pressurecharacteristics and a high stability

against oxidation.

6. The oil must have neutralization

qualities that will prevent the oil from

attacking the highly polished surfaces

of the bearings during periods of

prolonged operation.

7. The oil must contain anti-foamant

agents.

8. The oil must be suitable for vibrating

applications.

9. Oils containing suspended solids

such as graphite and/or Molybdenum

Disulfide (MoS2) are not

recommended for vibrating equipment

applications.

10. In cases where extreme ambient

temperatures are experienced, (10 F

and below or 100 F and above) you

are advised to contact us with the

details of your application so that all

factors can be considered for aproper lubricant selection.

Using the guidelines from the list above to

attain the proper quality of lubricant, the

following chart (Fig 4-2) will lead you to a

proper grade of lubricant for your

application. Using the bearing size,

operating speed and ambient temperature,

read across to find the recommended ISO

Grade Number. Units furnished with

automatic lubrication may have asupplemental manual to cover the oil

circulator/cooler.

Rule of Thumb Viscosity CheckSome machines will operate at higher temperatures than expected. To ensure the proper oil is being

used, drain a small quantity of oil from the machine after it has heated up to operating temperature.

Use a thermometer to measure the temperature of this oil and use the chart below.

Another way to do this would be to take the temperature of the bearing housing. The oil will generally

be 20oF hotter than the housing temperature. So a bearing housing temp of 185oF will give you an

oil temperature of 205oF. Use the chart below to make sure you have the correct oil. The chart is

based on a minimum of 105 SSUs. In marginal situations, use the next highest grade.

Hot oil could burn your skin.

Grease Lubricated MachinesIt is recommended that the customer

contact his lubrication dealer and purchase

grease that conforms to the following

specifications:

Lithium base grease with EP additive is

recommended.

The grease selected should not exhibit

thickening, separation of oil, acid formation

or hardening to any marked degree. It

should be smooth, non-fibrous and entirely

free from chemically active ingredients.

We do not recommend the use of greaselubrication when the ambient temperature is

below 10 F. or above 100 and/or the

BEARING OPERATING TEMPERATURE

is above 190 F. If grease must be used at

or above bearing operating temperature of

190 F., use Mobil 1 synthetic grease which

is 1100 SSU at 100 F and 144 SSU at

210 F with frequent lubrication cycles at

least once every eight (8) hours of

operation.

Food grade greases are available from allmajor suppliers. When selecting grease for

a food machine, the same guidelines will

apply.

Grease lubricated screens should be

lubricated at least once every ten (10) hours

of continuous running, or once every eight

(8) hour shift. See the Specification Sheet

for the recommended amount.

Cold Weather OperationGrease lubricated mechanisms require

special care when operated in cold

weather. Even though the majority of

lubrication manufacturers recommend the

same grade of lubrication for both summer

and winter operation, thickened grease

may overload the motor. In severe cold

weather, we recommend lubricating the

mechanisms at mid-shift or noontime. If the

mechanism is lubricated at night or in the

morning before the unit is started up, it will

require additional horsepower to start the

mechanism. If preheating is necessary, werecommend a series of heat lamps

directed towards the bearings and or shaft

assembly or a salamander-type heater

directed towards bearing and or shaft

assembly.

DO NOTuse an acetylene torch. Thiscould cause an explosion or fire.

A motor overload may also be due to aheavy concentration of grease in the shaft

housing. If this is the case, to completely

clean the shaft housing of all old grease, it

will be necessary to dismantle the

mechanism.

Checking OilDepending on what type of machine you

have, there will be an oil sight gauge in one

or both end covers for checking the oil. The

proper oil level would be to the center of the

sight gauge. Figure 4-5 shows the oil sight

gauge on an M-series (one end). Figure 4-

6 shows the oil site arrangement for an OA

or LP series(both ends).

Draining Unit

Refer to Figure 4-6, 4-7, 4-8, and 4-9 on thefollowing page(s). Depending on what

specific screen type you have purchased,

the draining procedure will slightly differ.

1. Remove bottom drain plug in tube

(Fig. 4-8) and/or each cover. Check

Specification Table in your installation

drawing for quantity of oil.2. Allow oil to drain completely.

3. Replace plug by using Permatex on

the threads before filling.

Filling UnitRefer to Figure 4-6, 4-7, 4-8, and 4-9 on the

following page(s). Depending on what

specific screen type you have purchased,

the filling procedure will slightly differ.

1. Remove breather in bearing housingor on each cover.

2. The breather vent on top of oil sight

glass in the cover must be cleaned or

removed so the oil can flow freely to

seek the correct level.

3. Fill tube or each cover to proper level

with recommended oil. Amount of oil/

grease is given on Specification

Sheet and on Lubrication Tag on the

side of the machine.

4. Clean and replace vents.

Page 5-1 OperationScreens

Section 5 - Operation

Operating SpeedThe operating speed is shown in theSpecification Table I. This was determined

to give you the optimum bearing life and

screening performance at the stroke

provided. Increasing the speed will

increase the screening of your unit, but will

reduce the bearing life and increase the

stresses in the structural members.

Do not change speed or stroke onyour screen without the approval

from Terex Simplicity. This will voidyour warrenty.

SafetyObserve the following precautions during

repair, overhaul, maintenance and

operation of the machine.

1. Always keep the area clean around

the screen.2. Before using cleaning solvents, read

and follow the safety precautions

printed on the containers. Never use

gasoline as a cleaning agent.

3. The area directly below the screen

should be closed off to protect other

personnel from falling objects.

4. All personnel working near the

equipment should wear approved

protective equipment.5. An emergency stop switch and a start

warning system must be provided

near the screen.

6. Remove personal jewelry before

working on equipment.

7. Before performing repairs or

scheduled maintenance, lockout thescreen and other equipment

pertaining to the screening operation.

8. Before the equipment is released for

operation, pick up all debris involved

in the repair including tools, used

parts, etc.

Inspection Before Start-upBefore starting up the plant each day, check

the following items:

1. Check the oil level in the screen.

2. Check breather caps(if applicable)

and remove any dirt buildup.

3. Look at the screen wire cloth to

determine if holes have worn through

the wire. Replace, as needed,

following the instructions in your

vibrating screen Owner/Operator

Manual.

4. Cleanup spilled material from aroundthe plant.

5. Record any observations about the

system in your plant log book.

Initial Start UpBefore starting the screen for the first time,

perform the following:

1. Lock & Tag Out machine.

2. Check the lubrication requirements

and level.

3. Check line voltage against motorname plate voltage.

4. Check the angle of inclination and the

level across both ends of the screen.

5. Make sure all safety-guards are in

place.

6. The vibrating screen body should be

free of any obstructions.

7. Place the start/stop switch in the ON

position.

8. Listen for any unusual noise, such asloose bolts, screen cloth, etc.

9. Check the screen motion for any

unusual pattern. This is done by the

following:

9.1.At each corner of the screen, attach

a white card with the top edge of the

card parallel with the ground. The

corner support bracket is usually

vertical to the ground so this would

be a good guide to line the side of

the card.

9.2.With a sharp pencil, lightly touch the

point to the card at 90. an elliptical

pattern will develop. You should takethree or four patterns at each corner.

A steady rest would be helpful for

this test.

9.3.Remove the cards and mark the

card location where the pattern was

taken, right, discharge, etc.

9.4.The patterns on each end of the unit

should be close to the same. If a

true pattern is difficult to obtain, then

a sidewise motion may be present.Move to the end of the screen and

pick a spot, such as the top corner

of the side plate and see. If this

sidewise motion is present, contact

us.

10. Start the take-away equipment before

starting the material feed.

6. Check all drive belts for proper

tensioning.

7. Check all guards for proper

installation.8. E-stop switches untagged and set in

the off position (released).

Normal Start UpIf the screen has been operated recently, it

is advisable to check the following items:

1. Lock & Tag Out machine.

2. The machine and screen cloth must

be clear of any material build-up. If the

screen is started with a material

buildup, damage to the cloth may

result.

3. Inspect the screen cloth for wear or

damage. Replace the cloth if

required.

4. Check screen cloth tension. Loose

cloth will fail prematurely.5. Check for any loose bolts on the body

and shaft assembly.

6. Check for material build-up in

hoppers, chutes, etc. There must be

three (3) inches clearance between

the vibrating body and any

surrounding object.

7. Grease the bearings per Section 4-

Maintenance of this manual.

8. If the screen has provisions for heated

screen cloth, refer to the

manufacturers instructions in starting

the heat to the cloth.

9. Start all discharge equipment that

removes the material from the screen

before starting feed.

10. Place the start/stop switch in the

ON position.

11. Listen for any unusual noise such as

loose bolts, screen cloth, etc.

12. Start material feed.

Shut-down1. Stop the initial material feed, allowing

screen to clear before shut down.

2. Place the start/stop switch in the

STOP position.

3. Lockout and tag out.

CleaningMaterial build up should be removed

whenever possible, particularly from under

the motor base pivot legs, as material

build-up will restrict movement of the base

and allow the v-belts to become loose.

Trouble Shooting ChartNOTE: Lock out and tag out machinery

before doing any maintenance.

Trouble Possible Cause Correction

Overheating

Check oil level. Too much or too little oil will causebearings to overheat, reducing internal clearance,resulting in seizure of bearing. Correct oil level andallow shaft assembly to cool before attempting torestart.

Failed Bearing

Rotate mechanism by hand for indication of bearingtrouble. Listen for grinding or unusual noise whichwould indicate excessive wear on rollers or races,broken roller or cage fracture. Replace both bearingsas a set after thoroughly cleaning the shaft housing.

V-belt Drive

Belt breakage, turning over in grooves, or jumping offthe sheave may result in loss of speed and boggingdown of machine. If necessary to replace belts,replace complete set to maintain uniform belt stretch.

Check drive and driven sheave for proper alignment.

Check belt tension. Adjust to correct tension if requiredby adjusting motor on base or moving the base.

MachineStoppage

Power FailureCheck power source and motor leads, fuses, starter

heaters.

NOTE: Lock out and tag out machinerybefore doing any maintenance.

Build up of Material

All surfaces in the vibrating body should beinspected for material build-up. Material clinging tothe unit will become dead weight and will affect thestroke and motion. Remove all material build-up onunit surfaces.

Screen Support

Check coil springs for indication of coil breakage or

possible build-up of material around the spring.

Check level of all four support points. Check forpossible settling of building support beams.

On units that are cable-suspended, check height ofsuspension springs. It is important that thesuspension spring compression be equalized andthat the unit is level. Uneven compression of thesprings may cause distortion in the unit, resulting inuneven vibration and premature failure of structural

members.

Feed Arrangement

Check feed arrangement to unit. Refer to the Partsand Service Manual for recommended feedingarrangements.Check for possible surge loading of the unit. If thisis a problem, the use of a surge hopper would berecommended.

UnevenMachine

Motion

Loose Body Parts

Check all body bolts. See Torque Chart in PartsManual for proper torque to tighten loose fasteners.

Check take-up rails (clamp bars) and deck coveringfor any looseness.

Uneven Loading

It is necessary that all the stretch is removed from thenew cables. This requires rechecking and readjustingafter approximately every 8 hours of operation until thelength is stabilized.

Incorrect Assemblyof Cable Fittings

Refer to instructions for correct assembly of cablefittings. (Page 3-4)

WhippingAdjust or install cable weights. Refer to instructionsregarding cable weights. (Page 3-5)

Cable LengthCable length should not exceed 12 feet nor should it beless than 4 feet. These measurements are takenbetween fittings.
