Method of Operation
Installation of the
granulator is on the production floor or in a
pit.
Material is fed into
the granulator by belt conveyor or by dumping
the content of a box directly into the feed
hopper of the machine. Once the feed hopper is
filled and the feed hopper cover closed the
hydraulic flap opens the cutting chamber and the
automatic cutting cycle of the machine begins.
A hydraulic cylinder
moves a pusher backward and forward. The pusher
feeds the material into the cutting chamber of
the granulator. The movement of the pusher is
automatically load controlled by the main motor.
In case of an overload the pusher stops and
retreats a short distance, then starts its
forward movement again. When the pusher is fully
extended and positioned at the front of the
hopper close to the rotor it will reverse to the
rear of the hopper and start a new forward
cycle. These cycles repeat each other until the
feed hopper is empty
Fine material gets
discharged through the screen into a pneumatic
discharge system. Bottom discharge onto a
mechanical conveyor or into a bin is available.
An open, alternating
slant cut rotor is standard. Bearings are
outboard and no grease can enter the grinding
chamber.
The screen has a
large open area; the standard hole size of the
screen is 12 mm ( 1/2"). Other screen sizes are
available. The material produced is ideal for
feeding densifiers, Plast-Agglomerators and
extruders with ram feeders. |
