Alpine‘s Polyplex shredder-granulator combines a vertically arranged shredder rotor with a granulator rotor.
The machine concept has been adapted to meet customer requirements
and was launched on the market as the Polyplex machine – and that at an
attractive price. In practice, the simultaneous feed of different
plastic waste constitutes a considerable advantage: presorting or dosed
material feed are now things of the past!
The material is charged to the shredder section by means of the
mechanical feed unit. The pre-comminuted material falls as the result of
gravity into the granulator section and is comminuted there to
granulator fineness. Whereas the shredder rotor permits self-dosing, the
granulator rotor guarantees product fineness values to approx. 5 mm.
The feed material is supplied by means of a pusher installed in the
channel. This allows feed material lengths of up to 6 metres. As a
result of the combination of shredder and granulator, the comparatively
small machine can process, for example, machine purgings of up to
several hundred kilos – if necessary together with profiles, pipes and
trims.
Blow mouldings/Injection mouldings:
The new
Polyplex by Hosokawa Alpine is universal in use for in-house recycling.
The decisive advantage: the combination of a shredder and a granulator
on one single shaft. The feed material doses itself when being charged
to the machine. Different plastic parts such as reject housings, sprues
and machine purgings can be mixed and then charged together. The
vertical design permits optimum accessibility to the grinding chamber.
This guarantees not only fast cleaning of the mill when changing the
product but also significantly reduces downtime.
Sheets and chunks:
The Polyplex shredder-granulator is ideal for the size reduction of
chunks and sheets. Chunks are pre-crushed in the shredder section. Even
chunks weighing several hundred kilos can be comminuted in one step to
granulator fineness – and that at considerably lower drive power. When
processing sheets and plates, the design of the inlet area guarantees
that sheets of any thickness can be comminuted without problem.
Profiles/Extrusion:
The horizontal feed channel can be adjusted in length. Channel lengths
of up to six metres pose no problem for profiles and pipes of standard
length. The bottom line: the Polyplex shredder-granulator constitutes
THE cost-effective comminution solution for profiles and pipes of any
length.
