The plastics waste is feed into the hopper (A) and falls down into the cutter housing,
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 onwards transport.
Granulators with designation ÒUÓ are equipped with an extraction blower (G) which
sucks the granulate out to a cyclone (H) for separation of air. On granulator models
with designation ÒBÓ, the hopper is equipped with a conveyor belt. The conveyor
can be equipped with a metal detector.
After this, the granulate is ready for re-use in the production machine, or to be trans-
ported to a container for later use.
The granulator is easy to clean, with a folding hopper and also good accessibility for
maintenance. Knives on the staggered rotor are disposable and should be replaced
when necessary. The rotating knives on an open rotor can be re-sharpened. Grinding
is done in a special grinding jig. (The jig is not included when the granulator is
delivered, but is a very practical accessory.)
