Never extend fingers through holes in screen.
Be sure that the v-belts are properly aligned and that tension is at its maximum.
Extreme care should be taken to see that all bolts are properly tightened at all times. During
the operation of the machine, rotor knife bolts may come loose. Although fine threads are
used on the rotor knife bolts because vibration does not easily loosen them, you should
inspect the tightness of the bolts frequently.
This machine is designed for the granulation of plastic materials. Do not feed any other
materials into the machine.

maintenance and total user responsibility will assist you in learning potential areas in need of
observation for danger.
Each individual must take responsibility for observing the prescribed safety rules as outlined.
All caution, warning and danger signs must be observed and obeyed. All actual or potential
danger areas must be reported to your immediate supervisor.
Chapter 1: Safety 9 of 37
1-4 Warnings and Precautions
Our granulators are designed to provide safe and reliable operation when installed and
operated within design specifications, following national and local safety codes.
To avoid possible personal injury or equipment damage when installing, operating, or
maintaining this granulator, use good judgment and follow these safe practices:
LEARN AND OBEY your company’s safety policy regarding granulating
equipment.
MOVING OR LIFTING THE GRANULATOR: Although our equipment is built
and engineered for great ruggedness in operation, care must be taken when moving
the machine along the floor or lifting it. Damage may occur to sheet metal covers,
electrical cabinets, or small brackets if pressure is applied to them when moving the
granulator. When lifting the granulator, be certain of total machine weight and the
capability of the lifting equipment. (See the Granulator Specification Sheets for
machine weights and dimensions.)
GRANULATOR LOCATION: Adequate area for routine maintenance should be
provided in order to open the machine for knife, screen, or cleanout service. Proper
service area clearances also should allow people who are working on the machine to
be clearly visible to others, thereby reducing the potential safety hazards.
SAFE HOUSEKEEPING: The work area must be kept clean and uncluttered during
periods of operation or maintenance. No hand tools or other metal objects should be
left on or around the machine. Any tools or other metal objects that mistakenly fall
into the hopper feed opening can cause severe damage to internal cutting chamber,
rotor and screen components.
SAFETY GLASSES OR A FACE SHIELD MUST ALWAYS BE WORN when
servicing or operating the machine. Although our machines are designed for the
maximum in fly back control, caution must be used when operating near the hopper
feed opening in order to guard against unexpected material fly back.
EAR PROTECTION may be required when operating the machine during
granulation of very hard or noisy materials. The Occupational Safety and Health Act
of 1970 has established guidelines for Permissible Noise Exposures (OSHA 1910.95)
that should be followed.
NEVER attempt to operate the granulator unless it is fully assembled with all guards
and interlocks in place and functional.
OBSERVE all danger, warning, caution and safety labels on the equipment.
Upon completion of any machine maintenance, be certain ALL SAFETY GUARDS
AND COVERS are securely and properly fastened prior to resuming machine
operation. All fasteners must be in place and properly tightened. ANY
SHORTCUTS MAY RESULT IN INJURY TO PERSONNEL OR DAMAGE
TO EQUIPMENT.
NEVER wear any loose fitting clothes, neckties, wrist watches, or dangling items
such as earrings, belts, or shoestrings. Jewelry, such as wristwatches, bracelets, or
rings should NEVER be worn. Long hair must be tied back or placed in a tight fitting
hairnet. NEVER lean against or rest hands or feet on the granulator when it is in
operation or open for maintenance. NEVER stand on the granulator when it is in
operation.
Chapter 1: Safety 10 of 37
ROTATION OF MOTORS: The correct rotating direction for the granulator motor
is clearly marked on the machine. Always check for proper rotation of motors.
Incorrect rotation direction can cause severe damage.
ELECTRICAL GROUNDING: All electrical equipment on the granulator must be
grounded in accordance to all local codes and Article 250 of the National Electric
Code.
ALWAYS DISCONNECT AND LOCKOUT the main electrical power to the
granulator before performing any service.
SAFETY INTERLOCKS MUST NOT BE BYPASSED. The mechanical and
electrical safety interlocks ensure the safety of personnel. They should never be
tampered with or removed for ANY reason. They should be checked frequently by a
qualified mechanic for proper operation.
NEVER modify the machine configuration or any individual component without
written notice from the factory.
For further information on granulator safety, installation and operation, see the American
National Standard for Plastics Machinery-Granulators, Pelletizers, and Dicers Used
for Size Reduction of Plastics-Construction, Care, and Use. ANSI B 151.11-1982.
We have long recognized the importance of safety and have designed and manufactured our
equipment with operator safety as a prime consideration. We expect you, as a user, to
abide by the foregoing recommendations in order to make operator safety a reality

Chapter 2: Functional Description
2-1 Models Covered in This Manual
This manual provides the necessary instructions for the installation, setup and maintenance of
our 20”x62” and 20”x72” models
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.
B Series granulators feature a massively built, low RPM high inertia rotor with chevron
knives. It accepts large parts and assures long, trouble-free service
The hopper is designed to remain stationary to allow for a smaller footprint and the screen to
pull out from the side for quick access into the cutting chamber.
These granulators are ideal for pipe, purgings, X-ray film, psi-consumer baled bottles, film
and fibers.
2-3 Typical Features and Components
Hopper
The hopper is an upright enclosure bolted to the top of the cutting chamber. The hopper 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. The
H Series, helical hog models do not have downstroke bed knife shields. The downstroke
bed knife shield is adjustable.
The screen is supported in position below 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 rotor carries the rotor knives. The rotation of the rotor produces a cutting action between
the rotor and the stationary bed knives, thus reducing the material size.
Drive System
The rotor is indirectly driven by the motor through v-belts. The motor shaft pulley, v-belts,
and the rotor shaft pulley are shielded by safety guards or sound enclosure.
The motor is mounted on an adjustable sliding base, which is mounted at the left end of the
granulator.
