Polyplex PPC

The new shredder-granulator with the distinctive name „Polyplex“ made by Hosokawa Alpine is THE innovative solution for the size reduction of plastic materials of any type.

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!

Technical highlights

Material feed:

Self-dosing material feed
Feed unit individually adaptable to the respective problem specification
Feed material can be fed continually or in batches

Comminution:

Granulator fineness values in one step

Handling:

Optimum access to cutting chamber, rotor and granulator knives
Short cleaning times
Easy operation and maintenance
Considerably reduced downtime

Cost efficiency - in comparison with 2-step solutions:

Significantly cheaper purchase price
Energy-efficient comminution thanks to only one drive being needed
Minimised space requirement
Minimum staff requirement for feeding the machine

Principle of operation

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.

Applications

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.
