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 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 kg/min. (2.2 lbs./min.). Under these operating conditions, the correct proportions of cut
and uncut particles will be present in the cutting chamber.
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.
