Tangential Feed Granulators Operation 17 of 39
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 on pages 12-16 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. The 20” x 24” model is rated at 1400 lbs./hr (636 Kg/hr), and the 20” x 36” model
is rated at 2000 lbs./hr (907 Kg/hr). Under these operating conditions, the correct proportions
of cut and uncut particles will be present in the cutting chamber.
WARNING! 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.
