GRANULATOR WITH STANDARD ROBOT/HAND FEED HOPPER
STANDARD 3-BLADE
OPEN ROTOR

The plastic waste is fed into
the hopper (A) and falls
down into the cutting
chamber, where rotating
knives (B) cut the plastics
waste against fixed knives
(C) to granulate.
A perforated screen (D) determines the size of the granulate. The screen is located
in the lower section of the cutting chamber and can easily be changed to give the
desired granulate size.
The granulate passes the screen and falls down through the outlet chute/granule bin
(E) to the outlet pipe (F) for transport onward.
After this, the granulate is ready for re-use in the production machine, or to be trans-
ported to a container for later use.
Granulators with designation “U” are equipped with an extraction blower (G) which
sucks the granulate out to a cyclone for separation of air. On granulator models with
designation “B”, the hopper is equipped with a conveyor belt. The conveyor can be
equipped with a metal detector.
The granulator is easy to clean, with a folding hopper and good accessibility for
maintenance. Knives can be re-sharpened. Grinding is done in a special grinding jig.
(The jig is not included when the granulator is delivered, but is available as an
option.)

16 OPERATION/MAINTENANCE
6.4 Troubleshooting
The granulator does not start:
•Verify that the emergency stop is not activated. Reset by turning the button(s) in
the direction of the arrow (counterclockwise).
•Check that the doors are properly closed. The granulator will not start if the
doors are not properly closed.
•Check that the hopper is properly closed. The granulator will not start if the hop-
per not is properly closed. Open the door and check that the lock clasps are proper-
ly tightened.
•Check the overload circuit breaker for the motor. The motor has an overload cir-
cuit breaker, F1, in the distribution box, which trips if you jam or overload the
motor. This is indicated in the window (A) which shows “0”.
To reset press the “Reset” button (B). Check that there is
no material left in the granulator before restarting.
•Granulator with blower. Check the blower motor
protection switch.The granulator will not start if the
blower does not start. Check the motor protection switch
Q2 in the distribution box.
If the motor protection switch has switched off the switch will be in position “0”.
Reset the switch button to position “1”. Check that there is no material left in the
granulator before restarting.
•Granulator with band conveyor. If the band conveyor does not start – check the
band conveyor´s motor protection switch. The band conveyor has a motor protec-
tion switch, Q3, in the distribution cabinet, which trips if you jam or overload the
conveyor belt.
If the motor protection switch has switched ”off” the switch will be in position ”0”.
Reset the switch button in position “l”. Check that there is no material left on the
band before restarting.
•Check the granulator knives and knife tolerance.
If the granulator knives are blunt and unsharpened, or if the knife clearance is
incorrect, this can result in stoppage. The granulator motor overload circuit breaker
will trip. Check the knives. Sharpen or replace the knives, or adjust the knife clear-
ance, see next chapter.
Also check the wiring diagram in chapter 9; supplements and deviations may be applicable.
The doors do not open:
•Verify that the emergency stop is not activated. Reset by turning the button(s) in
the direction of the arrow (counterclockwise).
•Verify that the main power is on and the main switch is in the ON position.
•The doors are on a time delay. Wait 2-3 minutes until the lamp on the distribution
box lights. Try opening the doors again.
