Central granulators

Hellweg Maschinenbau

Series 300 - Motor output: 7.5 - 30 kW

High performance granulators for heavy parts and high throughput

The Hellweg 300 series granulators enable gentle and thorough granulation of thick-walled mouldings, sheets, sprue cakes, pipes and profiles, etc, on account of the extremely high stability of the entire machine housing and through the high moment of gyration of the massive rotor that is made from one solid piece of metal.

A special rotor (BR version) enables single stage granulation of even extremely massive lumps from production start-ups.

The benefits:

  • performance-enhancing diagonal 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
  • almost maintenance-free
