Safety Considerations
AEC 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 to allow personnel safe
movement around the granulator during periods of
operation or maintenance. No hand tools or other
metal objects should be left on or about the machine.
Any tools or other metal objects which mistakenly fall
into the hopper feed opening can cause severe damage
to internal cutting chamber and screen chamber
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 flyback control, caution must be used
when operating near the area of the hopper feed
opening in order to guard against unexpected material
flyback.
EAR PROTECTION may be required when
operating the machine during granulation or very
hard/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, 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/feet on the granulator when it is
in operation or open for maintenance. NEVER stand
on the granulator when it is in operation.
ROTATION OF MOTORS: All rotating items in the
granulator are clearly marked on the machine. Always
check for proper rotation of motors.
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.
- 5 -
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 frequently checked by a qualified
mechanic for proper operation.
NEVER modify the machine configuration or any
individual component without written consent from
AEC
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 B151.11-1982.
AEC has long recognized the importance of safety and has designed and manufactured
it’s equipment with operator safety as a prime consideration. As a user, we expect you
will abide by the foregoing recommendations in order to make operator safety a reality.
SAFETY IS NO ACCIDENT

1 General Information
1-1 Introduction
This manual is intended to be used as a guide and reference
for personnel who will be installing, operating, and
maintaining the AEC GP1200 Series Granulator. The
purpose is to aid these individuals in applying efficient,
proven techniques, which will enhance productivity.
This Introduction includes a brief functional description, a

1-2 General Description
AEC granulators are designed to uniformly and consistently
size reduce your scrap. They have been engineered to
consistently deliver clean granulate with a minimum of
“fines”.
The rotor, on which the cutting knives are mounted, is a
fabricated steel unit supported by bearings mounted outside
the cutting chamber. A motor drives the rotor, which is
capable of producing high torque loads. The granulator is
equipped with a magnetic starter that is protected by
manually resettable overload heaters. The slanted rotor
knives produce a scissors cutting action which reduce the
possibility of feedstock jamming in the cutting chamber.
Motors are individually fused for maximum protection in
compliance with the National Electric Code.
The control enclosure houses all of the necessary wiring,
fuses, overload heaters, motor starter coils, along with the
115V control transformer and granulator operating controls.
The control enclosure is built to meet NEC, JIC (M.T.), and
ANSI-B regulations.
