Clear Hellweg advantages!

Proven by our customers:
- up to 50 % lower drive power is required
- up to 70 % less dust
- complete cleaning in 5-15 min
- safety while and after the size reduction process

Hellweg-rotors are fitted out with the double angled scissors cut technology. Produced from a single solid block of metal, the rotor has highest possible own weight, stability and torque - no welding! Suited for a save size reduction of all kinds of technical plastics.


  • Half the drive power rating:  up to 50 % lower drive power is required, due to the Hellweg shearing slanted cut geometry* - without a reduction of the throughput quantity - An advantage that pays back every hour.

  • Minimal dust level:  produced from a single solid block of metal, the rotor has highest possible own weight and torque and therefore brings very quiet running. The gentle slanted cut and quiet running make the main contribution to a low level of dust also for rough materials like PC, PA (with fibre glass) or POM.

  • No adjustment of the rotor:  in general, only the stator blades of Hellweg granulators are adjusted. This is an important advantage, as a significant amount of personnel costs can be saved. A direct example: changing and setting of an entire blade set of a Hellweg machine-side mill takes max. 10-15 minutes!  Not to forget that rotor and stator blades can be re-sharpened at low cost up to 50 times without special equipment (simple flat grinding).

  • No bridging or formation of long spike-shaped material:  Hellweg slanted cut granulators produce sharp-edged, low dust ground material with high homogeneity and without thermal degradation. Special screens prevent formation of spike-shaped particles in ground material and ensure high process security.

  • Fast and safe handling: safe and fast handling are always in the foreground  during design of a Hellweg granulator. By this is understood, e. g. fast cleaning, fast changing of screens and blades as well as design to avoid or reduce points of potential hazard.
