6. Operation and daily maintenance
6.1 Starting and stopping
The start and stop functions are controlled by a push-button on the electrical
cabinet.
NOTE: The
granulator should not
be stopped until it has
finished grinding all
the material in the
hopper and cutter
housing. Any
remaining material
can slow down the
rotor when it is re-
started which can
overload the motor
and trigger the
overload protector.
6.2 Inspection
There should not be any material in the granulator when the inspection is to be
carried out.
6.2.1 Daily inspection
• Emergency stop. Check the emergency stop function by starting the granulator
and then stopping it using the emergency stop button. The emergency stop is
reset by turning the emergency stop button in the direction of the arrow. The
machine can then be re-started by pressing “START”.
6.2.2 Weekly inspection
• Cables. Inspect all cabling in the machine to see that there is no wear or other
damage. For reasons of personal protection, damaged parts should be replaced
immediately.
• Safety switches. There are 2 safety switches, 1 for the locking clamp by the
screw feed, and 1 for the screenbox:
Screenbox: Check the safety switch by loosening the granule bin as described in
chapter 5.2. It should not be possible to start the granulator until the hoisting
mechanism's bar has been set in a vertical position after the granule bin has been put
into place.
Hopper: Open the hopper as described in chapter 5.2, but close and lock the granule
bin. Check the safety switch to the hopper by starting the granulator. It should not
be possible to start the granulator until the hopper is closed and the locking clamp is
back in position.
