Central granulators

Hellweg Maschinenbau

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.

The benefits:

performance-enhancing real helical scissors-cut
ideal granulate quality with very low dust
highly precise production, heavy housing welded
outer bearing assembly fitted, dust protection
wear resistant versions for reinforced plastics
structural design for easy, complete cleaning
stiff, non-twisting solid rotor
high performance belt drive
high throughput at low drive power
direct mounting of the knives on solid rotors
eliminating need for rotor knife adjustment
quick sieve and knife change
both rotor and stator knives can be
re-sharpened many times
hydraulic opening device
