Hosokawa Alpine unveils a new solution for the size reduction of plastic materials

"With the Combi-Grinder Polyplex PPC 50/120, a new development from Hosokawa Alpine, granulator fineness values are achieved in just one step. The joint drive makes the size reduction far more energy-efficient", says Josef Zöttl, creative mind and Senior Sales Manager in the Recycling and Granulators Division of Hosokawa Alpine's process technology business segment. At the K-Show, the new machine concept for the size reduction of plastic materials of all types will be presented for the first time. The unique factor: the machine has a vertically arranged rotor with a top-mounted shredder and the granulator section underneath.

Unbeatable flexibility

The machine's concept is quite simple: basically, shredder and granulator are combined to form one machine. With the aid of an intake unit, the feed material is automatically dosed and charged to the shredder-granulator combi. The feed rate can be individually adjusted to suit the problem specification. After passing through the shredder section, the pre-comminuted material falls into the granulator section and is comminuted there to granulator fineness. The Polyplex is especially suitable for in-house recycling. Thanks to its unique design, different plastic parts such as reject housings, sprues and purgings can be charged together. The vertical design of the mill also brings advantages when cleaning, enabling extremely easy access to the rotor and cutting knives. This guarantees not only fast cleaning but also significantly reduces downtime.
