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 3200 Series 32” x 63” and 32” x 84” granulators, which include models
BPHD, GPH and MSH.
2-2 General Description
The 3200 Series Granulators have a common cutting diameter of 18.1” (460 mm) and a
common throat size of 18” by widths of 40” or 56”. They are designed for big jobs in
reclamation of bulky blow-molded parts, pipe, purgings, sheet, film, fibers, and other high-
torque applications.
The machines conform to ANSI Standards B151.11 and NFPA 70, and they can be fitted with
screens having hole sizes to suit the particular application.
2-3 Typical Features and Components
Hopper
The hopper is a hinged, upright, 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 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 solid hardened rotor carries the rotary knives. High-strength alloy steel screws are used
for attachment of all knives.

3200 Series Granulators 63”and 84” 357563 •08/22/2019 14
Drive System
The drive system consists of a TEFC 1200 RPM motor set on an adjustable sliding base that is
mounted at the right side of the granulator. A belt guard shields the motor drive sheave,
rotor sheave and belts.
Discharge System
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 floor mounted airveyor type supporting the cutting chamber on its top surface
and the airveyor chute from below the top surface. This base should be fastened securely to
the surface beneath it.

3200 Series Granulators 63”and 84” 357563 •08/22/2019 15
2-4 Safety Features
Zero Speed Sensor
The zero speed sensor detects the motion of the rotor assembly. The sensor is interlocked
to the control circuits of the hydraulic system. If the rotor is turning, then the hydraulic
cylinders should not operate. Check the zero speed sensor periodically for proper
operation.
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.
Figure 1 shows some of the bolts, interlocks, and limit switches you may need to adjust
during maintenance. Refer to this diagram while performing the maintenance procedures.
ISO Safety Labels
A set of ISO labels are attached to the machine to warn of potential danger.

Chapter 3: Installation
3-1 Uncrating the Equipment
As shipped, the granulator with motor drive assembly and hopper are securely bolted onto
separate skids and covered with a wooden crate. The electrical cabinet, an optional item, is
similarly packaged when ordered. 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 granulator’s weight 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.
We recommend that the machine be lagged to the floor using the through-holes provided in
the base plate. Vibration isolation pads may be mounted between the base plate and the
flooring.
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 Installing the Infeed Hopper
When installing the infeed hopper, check the weight of the hopper and make sure to size
the hoist and accessories accordingly. Use the following procedure to install the hopper:
1. Run strapping or chains of appropriate lifting capacity to the lifting handles on the
sides of the hopper.
2. Use a hoist of appropriate capacity to lift the hopper into position.
3. Fasten the hopper to the upper cutting chamber using the hardware supplied.

3200 Series Granulators 63”and 84” 357563 •08/22/2019 17
3-3 Electrical Connections
Before operating the granulator, it is extremely important that the machine is correctly
wired into the plant power source by a licensed electrician. All electrical equipment must be
properly grounded in accordance with local and national codes to protect personnel from
electrical shock. A fusible, lockable disconnect between the plant power source and the
machine electrical cabinet is highly recommended.
To wire the granulator, run power from the plant source through a lockable, fusible
disconnect to the machine electrical control panel. From the main electrical control panel,
make the necessary control circuit connections to the open/close control panel, main drive
motor, and any auxiliary motors or connections.
To wire the open/close control panel, run power from plant source through a fusible
disconnect to the machine-mounted open/close control panel. Wiring from the open/close
control panel to the safety switches, zero speed sensor, and cutting chamber and screen
hydraulic system is done at the factory.
Refer to the wiring diagram in Section 7-7 for wiring connections for typical machine
applications. Check the wiring diagram supplied for any wiring that is specific to your
application.
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 the switch on at main power supply.
4. Jog the 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.
6. 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 7. If blower motor rotation is incorrect, complete the
following procedure:
a. Shut power OFF and disconnect incoming power supply line.
b. Reverse any two of the three power line connections to the blower motor.
c. Re-connect the incoming power supply line, and recheck the blower motor
rotation.
7. Allow all motors to run up to speed for at least 30 seconds.

3200 Series Granulators 63”and 84” 357563 •08/22/2019 18
3-4 Accessing the Cutting Chamber
You will need to access the cutting chamber before initial startup and for various
maintenance procedures. Before accessing the cutting chamber, make sure no one is near
the hydraulic cylinders or hopper. The hydraulic cylinders should not operate until the rotor
is completely stopped. If the hydraulic system does operate while the rotor is still turning,
immediately shut down the machine and call for maintenance to adjust it.
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 cutting chamber interlock actuator screw with a box wrench or
ratchet wrench. Make sure the end of the interlock actuator screw is visible and
clear of any contact. When disengaged, the interlock opens the electrical control
circuit to the motor and prevents the machine from running.
3.Turn the cutting chamber hold-down fasteners counterclockwise to remove
them, and place them on the lip of the upper cutting chamber. There are
fasteners on the front and rear of the granulator.
4.Start the cutting chamber hydraulic cylinders from the open/close control panel
by turning the CC/Hopper switch to the “Raise” position and pressing the button
in the center of the switch. Hold the button until the hopper stops, and then
release the button and return the switch to the off position.
5.Position the rotor so that a blade is at the top center, pivot the cover plate to
the open position, and turn the rotor locking nut until it extends into the guard
through the opening provided. Tighten it against the rotor flywheel to keep the
rotor from turning.

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. Make sure that no one is near the hydraulic cylinders or hopper, and clear the
mating surfaces of the cutting chamber of any debris that might prevent tight
closure.
2. Unscrew the rotor locking nut.
3. At the open/close control panel, turn the CC/Hopper switch to the “Lower” position
and push the button in the center of the switch. Hold the button until the hopper
stops, and then release the button and return the switch to the off position.
4. Replace the cutting chamber hold-down fasteners by turning them clockwise until
they are tight against the chamber housing. There are fasteners on the front and
rear of the granulator.
5. Engage the cutting chamber safety interlock by turning the actuator screw
clockwise. Make sure the screw is fully seated against the top surface of its housing.
6. Replace line fuses, turn power on, and remove the out of service tag from the
machine.

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:
Before operating the granulator, insure that the granulator has been correctly
assembled and wired.
1. Check the interlock switches and zero speed sensor as describe in Sections 5-6 and
5-7.
2. Check the screen as described in Section 5-5.
3. Access the cutting chamber as described in Section 3-4.
4. 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.
5. 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.
6. 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 0.15 mm (0.006”) to 0.20 mm (0.0008”). This clearance
is slightly greater at the center of the knives.
Note: Recheck knife clearance after the first 24 to 36 hours of operation.
7. To make the adjustment on the bed knives, the bed knife adjusting screws 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
screws to 640 Nm (472 ft. x lbs.).
Note: All screw tightening torque figures are for un-lubricated thread conditions. All
Screw threads must be clean of any residue before installation to prevent galling
8. 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.
Note: After initial start-up, the rotor knife retaining screws should be
checked after 8 hours running to be assured that 640 Nm (47 ft. x 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.
