OPERATION
SECTION 5-2 to 5-3
Initial Startup
CHECK THE MOTOR ROTATION DIRECTION
Unlock the power.
Push the start-stop pushbutton in quick succession to start the machine, then, let it coast
without power.
While the machine is coasting to a stop, check the V-belt direction by looking
through the slots in the drive guard. The top of the V-belt should move toward the
front of the machine as indicated by the arrow plate on top of the guard cover.
If the motor rotation is not in the proper direction, TURN OFF and LOCK OUT the power
per OSHA 1910.147 or ANSI Z244.1, 1982 (Lockout/Tag out of Energy Sources).
Call a qualified electrician to correct the problem. Refer to Section 3 for procedure.
RUN THE MOTOR
If the motor is turning in the proper direction, restart the machine with the start pushbutton
on the electrical cabinet and allow the motor to run up to speed for 30 seconds.
The granulator is now ready for operation.
DISCHARGE AIR ADJUSTMENT
If the discharge airflow is insufficient, the granulate can accumulate in the discharge transition just
below the screen cradle. The buildup eventually backs up into the cutting chamber where continued
agitation by the rotor can cause overheating and possibly stalling of the motor.
The discharge damper may be located on either side
of the machine. On this machine it is located under
the rotor sheave inside the drive compartment; it
controls the amount of air that flows through the
discharge transition and the discharge blower. Adjust
it as shown to obtain the required discharge
conveying velocity, while maintaining maximum
airflow through the cutting chamber.
