1426-i Granulator Chapter 2: Functional Description 9 of 37

Chapter 2: Functional Description

2-1 Models Covered in This Manual

This manual provides the necessary instructions for the installation, set-up, and maintenance
of our 14 x 26 granulator.

2-2 General Description

This granulator is a rugged, rotary-cutting machine specifically designed to cut, chip, and
granulate the toughest plastic materials with a minimum expenditure of horsepower.

A massively built, low RPM, high inertia rotor with chevron knives accepts large parts with
ease and assures long, trouble-free service. The bed knife block is made of heavy steel, and
the cutting chamber is made of a thick steel plate with integral oversize bearing housings.

The hopper is designed to tilt back, and the screen cradle to swing down for quick access into
the cutting chamber.

Reclamation of sprues, runners, and small parts for inclusion and application in any type of
molding or extrusion equipment is designed-in capability and depending on screen size used,
this machine will provide pellets or chips to meet most requirements.

With no enclosures, this granulator sets the industry standard for noise reduction with 85
DBA or less in almost all applications.

1426-i Granulator Chapter 2: Functional Description 10 of 37

2-3 Typical Features and Components

Hopper

The hopper is a hinged, upright, tray-feed enclosure with sound dampening. It tilts
completely out of the way for unobstructed access to the cutting chamber. It is designed to
facilitate feeding of material to the rotary knives and to prevent chips thrown from the cutting
chamber from reaching the operator.

Cutting Chamber

The cutting chamber is a rectangular enclosure comprising the main frame, the bed knives,
the bed knife shields, a balanced rotor, and a screen.

The main frame of the cutting chamber carries the bed knives and the bed knife shields. Both
the bed knives and shield are adjustable, and the bed knives have reversible cutting edges for
extended life.

The internal surfaces of the solid steel cutting chamber are machined to an exceptionally
smooth finish for ease of clean-out. The scissor-type cutting action of the chevron rotary
knives gives optimum cutting efficiency with low power consumption.

The screen is mounted in a swing-down cradle, positioned just below the rotor and acts as a
separating barrier to the granulated material, retaining the material in the cutting chamber
until the particle size is such that it will pass through the screen holes.

The open-type, high-alloy steel rotor carries the rotary knives. High-strength alloy steel
screws are used for attachment of all knives.

Drive System

The drive system consists of a drip-proof 1800 RPM motor set on an adjustable sliding base
that is mounted below the granulator cutting chamber. The motor drives the rotor with banded
V-belts for insured RPM control. Safety guards shield the motor shaft pulley, V-belts and the
rotor shaft pulley for complete operator safety.

Discharge System

The granulated material that falls through the screen is collected by a discharge chute beneath
the cutting chamber and directed into a bin. The bin can be removed from the front or left
side of the granulator for emptying.

On models fitted with an airveying system (optional), the granulated material that has fallen
through the screen is collected in a transition piece located beneath the cutting chamber. The
transition piece is connected to a blower, which conveys the granulated material through
ducting to the cyclone separator. The cyclone separator allows the granulated material to drop
out of the air system into a container.

Base

The base is a tube-mounted, bin-type construction with tubes located for forklift pick-up.

1426-i Granulator Chapter 2: Functional Description 11 of 37

2-4 Safety Features

Motor Starter

A magnetic motor starter with control transformer must be used when safety switches are
installed. Manual starters should not be used under any conditions.

Safety Switches

Safety switches at all access covers are wired into the starter control circuit. The machine
cannot be started when these parts are open. However, for safety purposes, the machine
should be disconnected from the power lines by a disconnect switch or by removing the plug
from its receptacle. Check all safety switches periodically for proper operation.

Safety Tags

A set of metal plates is attached to the machine to warn of potential danger.

1426-i Granulator Chapter 3: Installation 12 of 37

Chapter 3: Installation

3-1 Uncrating the Equipment

The complete granulator, including accessory and auxiliary equipment, is skidded for
shipment. Refer to the Appendix for detailed dimensional data and pertinent weights.

Prepare in advance the site you have selected for installation of the granulator. Be certain
that the area to be occupied by the machine is clean, level, and free of obstructions. The
machine should be set on a concrete floor, and care must be taken when moving the machine
across a hollow timber floor, so that the point loading of the casters does not cause damage.
The site you have selected must have a floor rating to adequately support the weight of the
machine. If necessary, use steel shims to level the machine.

Locate the machine so that access is given to electrical components, screen, and hopper.
Maintenance personnel should have unobstructed access to the units on which they will be
working.

To avoid squeezing people working near a machine, there should be adequate clearance
maintained between machines, walls, or partitions. Hinged doors and covers should have full
swing. Restrictions may force work in cramped quarters. An off-balance operator with an
awkward reach into a partially obscured area is unsafe.

If inspection after shipment has revealed no shipping damage, unpack the unit by removing
all hold-downs, tie-downs, bolts, nuts, etc. Remove the envelope with the electrical
schematics and instruction manual from the base evacuation area.

You can now have the machine lifted from the skid. To lift and move the granulator safely
and correctly, cover any sharp corners or edges, and use the type of equipment that has the
most appropriate features and capacity. Use the designated lifting points, and do NOT lift the
machine by the hopper handles or guards.

3-2 Belt Tensioning

Belt drives should initially be tensioned at the “run-in” recommended force. Check the
tension at least twice during the first two days of operation. After the belts have seated
themselves in the sheave grooves and the initial stretch is removed, re-tension the belts to
“normal running” and check periodically to maintain tension at the recommended value. See
Section 5-6 on page 22 for the belt tensioning procedure.

1426-i Granulator Chapter 3: Installation 13 of 37

3-3 Electrical Connections

Granulator controls (if ordered) are pre-wired before shipment. The customer is required to
provide a suitable fused supply with a disconnect switch and a cable for the incoming line to
the starter.

Refer to the technical specifications in the Appendix for horsepower, voltage, phase, and
frequency requirements to determine the size and rating of the supply cable required.

If optional controls are required, an electrical wiring diagram will be provided with the
machine in addition to the basic electrical diagram.

When the customer is providing either the motor or the starter, the machine must be wired in
accordance with the basic electrical diagram and the starter manufacturer’s instructions.

Use the following procedure to complete the electrical connections:

1. Check to be certain that the starter heater elements correspond with the motor

requirements. If controls are not supplied, the limit switches supplied on the machine
must be wired into the circuit at the common terminal box.

2. Check that the limit switches are closed.

3. Turn switch ON at main power supply.

4. Jog motor by pressing the START and then the OFF button. This starts and stops the

motor.

5. With the electrical power ON, check that the motor rotates in a clockwise direction at

the viewing port in the belt guard. If motor rotation is correct, continue to the next
step. If rotation is incorrect, complete the following procedure:

a. Shut power OFF and disconnect incoming power supply.

b. Reverse any two of the three power line connections to the machine.

c. Re-connect the incoming power supply line and turn ON the main power

switch to recheck motor drive rotation.

1. If Airveying system (optional) is fitted, press the Airveyor START button, and check

the blower motor rotation. The blower motor should rotate in a counterclockwise
direction. If blower motor rotation is correct, continue to step 6. If blower motor
rotation is incorrect, complete the following procedure:

d. Shut power OFF and disconnect incoming power supply line.

e. Reverse any two of the three power line connections to the blower motor.

f. Re-connect the incoming power supply line, and recheck the blower motor

rotation.

6. Allow all motors to run up to speed for at least 30 seconds.

1426-i Granulator Chapter 3: Installation 14 of 37

3-4 Accessing the Cutting Chamber

You will need to access the cutting chamber before initial startup and for various
maintenance procedures. Use the following procedure to access the cutting chamber:

1. Turn the main power off, remove the line fuses, and tag the machine as out of

service.

2. Unscrew the front cover interlock screw. This operates a limit switch, preventing the

machine from being started.

3. Lift off the front cover to gain access to the hopper crank mechanism.

4. At the rear of the hopper near the bottom, remove the cover that provides access to

the downstroke shield, and loosen the five shield hold-down screws. The four
remaining side screws are more easily loosened from the top.

5. Unscrew the hopper clamp screw. This operates a limit switch, preventing the

machine from being started.

6. Tilt back the hopper (using the hand crank provided) by turning the pivot screw in the

top front of the left hand guard. This permits access to the cutting chamber.

7. Remove the screws holding the screen cradle and carefully lower the cradle and

screen. Remove the screen from the front.

3-5 Closing the Cutting Chamber

After completing any maintenance or adjustments inside the cutting chamber, use the
following procedure to close the cutting chamber and resume use of the granulator:

1. Replace the screen in the cradle, making sure that the far edge is trapped beneath the

bed knife block. Tighten the cradle screws.

2. If the front shield was removed, replace it and tighten the screws.

3. Check that the cutting chamber is clear of any parts or materials.

4. Close the hopper and tighten down the clamp screw.

5. Check that the gaps between the seal strips and cutting chamber are less than 0.15mm

(0.006”). Release the screws to make any adjustment and retighten when adjustment
is complete.

6. Replace the front cover and tighten the interlock screw.

7. Replace line fuses, turn power on, and remove the out of service tag from the

machine.

1426-i Granulator Chapter 3: Installation 15 of 37

3-6 Initial Start-up

This machine has been run under power and tested at the factory prior to shipment. The
necessary settings and adjustments have been made so that a minimum amount of setting up
or re-adjustment is required when starting up the machine in its new location.

With all electrical, mechanical connections and lubrication requirements having been
attended to, the following start-up steps should be carefully carried out before attempting to
place any material into the infeed hopper. Use the following procedure to prepare the
machine for initial start-up:

WARNING! Before operating the granulator, insure that the granulator has been

correctly assembled and wired.

1. Access the cutting chamber as described in Section 3-4 on page 14.

2. Thoroughly clean the rust preventative materials or grease from the hopper, the inside

of the cutting chamber, knives, rotor, screen, discharge system, and exterior of the
machine. Do not use solvent on any of the painted areas, as solvent may damage the
paint.

3. Check all rotor knives to make sure they are properly seated on the rotor and securely

fastened. Although they are ground as a set, one knife will probably be .001” to .002”
higher than the others. This should be marked and used when adjusting the bed
knives for proper clearance.

4. Use a feeler gauge to check the clearance between the rotor and the bed knives by

turning the rotor backwards. Rotating the rotor backwards gives a better feel and does
not cut the gauge, should the knives be too close. Check the knives on each end only.
Proper clearance is 0.10 mm (0.004”) to 0.15 mm (0.006”). This clearance is slightly
greater at the center of the knives.

Note: Recheck knife clearance after the first 24 to 36 hours of operation.

5. To make the adjustment on the bed knives, the bed knife bolts should be hand

tightened to hold the knife firmly against the knife seat while adjusting the knife
forward using push and pull screws. After the clearance is set, torque the 16 mm
screws to 266 Nm (196 ft. lbs.).

Note: All screw tightening torque figures are for un-lubricated thread conditions.

Screw threads should be wiped with an oil-dampened cloth before installation
to prevent galling.

6. With the exposed parts of the machine thoroughly clean, and all knife clamping bolts

securely fastened, close the cutting chamber as described in Section 3-5 on page 14.

Note: After initial start-up, the rotor knife retaining screws should be

checked after 8 hours running to be assured that 266 Nm (196 Ft. lbs.).
Of torque is maintained. Thereafter, rotor knife retaining screws
should be checked weekly.

Note: The rotor must be rotated at least two rotations every 30 days to prevent

brinnelling and corrosion of raceways.

Chapter 4: Operation

4-1 Start-up

Before starting the machine, check that the rotor rotates freely by rotating it by hand from
outside the machine using either the coupling or the sheave depending on the type of drive.
Inspect the cutting chamber carefully to insure that nothing has fallen into it. Make sure all
screws and bolts are properly secured. Check all electrical connections and motor rotations.
See Chapter 3 on pages 12-15 for detailed set-up instructions. Allow all motors to run up to
speed for at least 30 seconds.

4-2 Feeding the Granulator

Feed the granulator through the opening in the hopper. The method of feeding the granulator
depends on the physical form and nature of the material being processed.

For maximum efficiency, the granulator should be fed at a rate that is consistent with its
capacity; i.e., if the granulator is rated at 60 kg/hr (132 lbs./hr.), then the general feed rate is 1
kb/min. (2.2 lbs./min.). Under these operating conditions, the correct proportions of cut and
uncut particles will be present in the cutting chamber.

WARNING! Under no circumstances should the operator attempt to reach into the

hopper to dislodge any bridged or jammed material while the granulator is
in operation. To clear the hopper of bridged or jammed material, the
machine main power must be turned off and the machine isolated.

4-3 Clearing a Jammed Cutting Chamber

Never attempt to free a jammed machine by placing hands on the rotor, rotor knives, or inside
the cutting chamber. Hands must be kept clear of the rotational path of the rotor knives.

Good footing on a clean floor is essential and the body should be well braced to guard against
loss of balance should the jam suddenly come free.

Use the following procedure to clear a jammed cutting chamber:

1. Disconnect and lock out power.

2. Be certain that the rotor is motionless.

3. Open the machine as instructed in Section 3-4 on page 14.

4. Use a pry bar to exert force on the rotor, usually in the direction opposite normal

rotation. A leather mallet and a block of wood of sufficient length to keep hands
away from path of knives can be used if necessary.

5. Use pliers to remove material from the cutting chamber, keeping in mind that the

removal of material may cause rotation of the rotor and rotor knives.

6. After clearing the jam, be certain that the screen and all guards and covers are

secured in place before connecting power and starting the machine.

4-4 Shut-down

Use the following procedure to properly and safely shut down the machine:

1. Stop all feeding of material.

2. Allow the granulator to run until the cutting chamber is completely empty.

3. Press the drive motor “stop” button. This shuts off the rotor drive motor.

4. After the granulator has stopped, press the airveyor stop button (if applicable) located

at the blower motor.

5. Turn the main power switch to off.

no lubrication for a month under usual operating conditions. If the machine is operated
continuously, it may be desirable to lubricate the machine every two or three weeks. This
machine should be lubricated with a high temperature bearing grease. We suggest Alemite
#38, Sun Oil #844, Sunoco Prestige 741EP, Sovarex #2, Shell EP Grease #1, Mobilux EP-2,
or Esso Multi-purpose Grease H.

1426-i Granulator Chapter 5: Maintenance 19 of 37

5-3 Testing the Interlock Switches

Test the proper operation of interlock switches daily, or at least weekly, depending on
machine usage. Two- or three-shift operations require daily testing of the interlock switches.

Because granulate material or dust can collect or build up inside the belt guard, periodic
cleaning and removal of material may be required to maintain proper operation of interlock
switches and the belt drive. An inspection port is provided on the belt guard to observe the
belt movement and rotation. Depending on plant operating conditions, a flashlight may be
required to observe the movement.

Always be sure that the tapped holes for the interlock actuator bolts are free of dirt, plastic
dust, or particles before replacing the actuator bolt.

Do not use air wrenches to remove or install interlock switch actuator bolts. The time
required to un-thread the actuator bolts with conventional manual wrenches should allow the
rotor to come to a complete stop.

WARNING! Always be sure the rotor has come to a complete stop before opening any

cover, guard, or hopper.

If testing determines that an interlock switch is not working, be sure to shut down the
granulator, pull it out of service, and lock out the main power before removing the front
cover, opening the hopper, or attempting to gain access to the interlock switches. The
interlock switches and mechanisms can be accessed by removing the belt guard on the right
side of the granulator. In some cases, it may be necessary to remove or slide back the
flywheel to completely remove the interlock switch assemblies.

Use the following procedure to test the interlock switches:

1. Press the Stop/Start Button to shut down the granulator.

2. Disconnect and lock out main power supply to the granulator.

3. Using the wiring diagram supplied with your granulator or by tracing the wires from

the interlock switches, locate the interlock switch wire numbers on the terminal strip
in the control panel. They will usually be marked #1 & #3, #3 & #4, and #4 & #5,
etc. depending on how many switches are used on your machine.

4. Connect the leads of an ohmmeter across each interlock switch or across all interlock

switches (wires #1 & #5). Set the ohmmeter on the lowest resistance scale. When the
interlock actuator bolts are in place and properly activating the switch, the ohmmeter
will read zero resistance.

5. Loosen the actuator bolt of each interlock switch (usually about 3 or 4 turns) one at a

time, until the ohmmeter reads infinite resistance. If the meter reads infinity before
the bolt can be completely removed, the interlock is working. If the actuator bolt can
be completely removed and the resistance does not read infinity, the interlock is NOT
working, and the complete mechanism, including the switch, must be removed and
disassembled to determine the cause of the malfunction.

If an ohmmeter is not available, the interlock switches can be checked by loosening the
actuator bolt while the machine is running, until the power to the motor disconnects and shuts
down the machine. The indicator light on the Stop/Start Button will go out or you may be
able to hear a change in sound when the power disconnects. If the actuator bolt can be
completely removed and the power does not disconnect, the interlock switch is not working
and the complete mechanism needs to be removed and disassembled to determine the cause
of malfunction.

1426-i Granulator Chapter 5: Maintenance 20 of 37

5-4 Replacing and Adjusting the Knives

During use, the clearance between the rotor knives and the bed knives will increase due to
wear. This is a normal condition that requires re-setting this clearance once or twice before it
is necessary to remove the knives for regrinding. Check the knives weekly for wear,
clearance, exposure, and screw tightness.

When new knives are fitted to the machine, adjustment after eight hours of running time may
be required.

Before assembling a new or reground set of knives, make sure the knife seats and mounting
holes are clean. Do not use grease or oil on screws or tapped holes when assembling the
knives.

Knives must be replaced in complete sets, otherwise it will not be possible to obtain even
clearance between the rotor knives and bed knives.

WARNING! Before applying a wrench to any knife bolt, be certain that the rotor is

blocked to prevent rotation. One such method is to use a block of wood at
least 1 1/2” thick between a knife and a fixed portion of the frame.

Rotor Knives

We recommend that the rotor knife screws be replaced with new screws every sixth knife
change to reduce the risk of screw failure due to overstretching. Screws must be replaced
with the type specified in the spare parts list. Use the following procedure to replace or adjust
the rotor knives:

Caution! Rotor knives should be changed one seat at a time to prevent rotor from

being rotated in an out-of-balance condition.

1. Access the cutting chamber as directed in Section 3-4 on page 14.

2. Remove the bed knife shield screws and lift off the bed knife shield.

3. Remove the screws holding the bed knives, and remove the bed knives.

4. Remove the screws holding the knives to the rotor and remove the rotor knives.

5. Thoroughly clean the knife seats, and replace the knives.

6. Lightly tighten the screws and check that a 0.04 mm (0.0015”) feeler gauge will not

pass between the back of the knife and the knife seat. Tap the knife gently with a
rawhide hammer if necessary to close the gap.

7. Tighten the screws evenly and torque the high tensile 16 mm screws to 266 Nm (16

ft. lbs.)

Note: Bolt threads should not be oiled. Wipe thread with and oil-dampened cloth.

8. Re-check the gap between the back of the knife and the knife seat. If necessary,

readjust the knife.

9. Adjust the clearance between the bed knives and rotor knives. (See “Bed Knives” on

page 21.)

1426-i Granulator Chapter 5: Maintenance 21 of 37

Bed Knives

We recommend that the same screws and washers be re-used only when the bed knives have
been repositioned or re-ground. When blunt knives are discarded and replaced with new
knives, use new screws and washers. This will reduce the risk of screw failure due to their
overstretching. Screws and washers must be replaced with the type specified in the Spare
Parts List. Use the following procedure to replace or adjust the bed knives:

1. Access the cutting chamber as directed in Section 3-4 on page 14.

2. Remove the bed knife shield screws and lift off the bed knife shield.

3. Remove the screws holding the bed knives, and remove the bed knives.

4. Before installing and adjusting the bed knives, check all rotor knives to make sure

they are properly seated on the rotor and securely fastened.

5. Thoroughly clean the knife seats.

6. Replace the bed knives on the bed knife seat and tighten the screws until they are

finger-tight.

7. Use the adjustment screws to set the knife clearance to 0.10 mm – 0.15 mm (0.004” –

0.006”). The clearance should be measured with a feeler gauge at the ends of the
knife, by rotating the rotor sheave backwards by hand. The clearance is slightly
greater at the center of the knives.

8. Tighten the bed knife screws evenly and torque the 16 mm screws to 266 Nm (196 ft.

lbs.).

9. Replace the bed knife shield and adjust the shield using its push and pull screws so

that its front edge is within 1.6 mm (0.062”) of the bed knife edges. The downstroke
shield is adjusted with shims that are placed under the side tabs. Unused shims are
stored under the head of the screws on top of the tabs.

10. Make sure all screws, bolts, and nuts are properly tightened.

5-5 Sharpening the Knives

Under normal operating use, the cutting edge of the knives will eventually become dulled,
resulting in reduced cutting efficiency. The blunt knives may either be re-ground to restore
the cutting edge, or replaced with new knives when regrinding is not possible.

Rotor Knife Sharpening

The rotor knife can be re-sharpened to the diagram below. The three knives must be
sharpened to within 0.076 mm (0.003”) of each other. Greater dimensional variations will
cause difficult when setting the knife gap and create other serious complications.

When sharpening, it is not harmful to allow a few small nicks to remain in the cutting edge.
Grinding the cutting edge until perfectly clean can sometimes be wasteful.

Do not install rotor knives that are smaller than the minimum dimension shown, because the
fasteners that secure these knives will interfere with the cutting circle. If the rotor cannot turn,
the bed knives will be damaged.

Bed Knife Sharpening

Each bed knife is provided with four cutting edges. When the exposed edges become blunt,
the knives can be turned and repositioned to present the new cutting edges. When re­sharpening is necessary, refer to the diagram below.

It is not necessary to grind bed knives to the closely matched tolerance of rotor knives. As
with rotor knives, small nicks in the cutting edges will not seriously affect knife cutting
efficiency. Bed knives smaller than the minimum dimensions shown must be replaced along
with the fasteners that secure them.

1426-i Granulator Chapter 5: Maintenance 23 of 37

Adjusting Belt Tension

For continuous reliable operation of the granulator, it is important that the belt tension is
correct. Correct tension reduces wear on rotor and motor bearings and keeps belt slip to a
minimum. Figure 2 gives the recommended force to deflect each belt by an amount equal to
the belt span divided by 64. A gauge is available through the sales department to measure the
deflection and force. Use the following procedure to adjust the belt tension:

Note: The deflection force value shown must be multiplied by the number of V-belt

elements.

1. Turn off the granulator at the main isolator switch and remove fuses.

2. Remove the cover to gain access to the belts, and remove the right side and rear base

panels to gain access to the motor base.

3. Turn the adjusting screw on the motor slide base to tension the belts as required (See

Figure 2).

4. Re-tighten the screws, making sure the pulleys are in correct alignment.

5. Replace the covers.

belts and pulley.

3. Turn the adjusting screw on the motor slide base to release all tension from the belts.

4. Remove the belts

5. Install the banded V-belts and proceed to adjust the belt tension as instructed in

Section 5-6 on page 22.

6. Replace base panels and guards.

7. Replace the line fuses and turn main power on.

1426-i Granulator Chapter 6: Troubleshooting 25 of 37

Chapter 6: Troubleshooting

6-1 Introduction

The utmost in safety precautions should be observed at all times when working on or around
the machine and the electrical components. All normal trouble-shooting must be
accomplished with the power off, line fuses removed, and with the machine tagged as out of
service.

The use of good quality test equipment cannot be over-emphasized when troubleshooting is
indicated. Use a good ammeter that can measure at least twice the AC and DC current that
can be encountered for the machine. Be sure that the voltmeter has at least minimum
impedance of 5,000 OHMS-per-volt on AC and 20,000 OHMS-per-volt on DC scales.
Popular combination meters, VOM and VTVM can be selected to provide the necessary
functions.

Before making haphazard substitutions and repairs when defective electrical components are
malfunctioning, we recommend that you check the associated circuitry and assemblies for
other defective devices. It is common to replace the obviously damaged component without
actually locating the real cause of the trouble. Such hasty substitutions will only destroy the
new component. Refer to wiring diagrams and schematics.

Locating mechanical problems, should they occur, is relatively straightforward. When
necessary, refer to the parts catalog section.
