Series 450 - Motor output: 22 - 75 kW

Central granulator - Series 450 - Motor output: 22 - 75 kW

Heavy duty granulators for hollow bodies High performance for voluminous parts and high throughput

The Hellweg 450 series granulators enable gentle and thorough granulation of voluminous and large surface area plastic parts such as bumpers from the automotive industry or parts dismounted from old cars like plastic tanks, door interior claddings, canisters etc on account of the real helical scissors-cut and the high moment of gyration of the massive rotor that is made from one solid piece of metal.

In connection with a 7-knives rotor also higher material outputs can be reached as a central application. Sheets, pipes, profiles and thick-walled mouldings, etc can also be granulated in a save way.
