Series 250 - Motor output: 1.1 - 2.2 kW

Slow running granulators - Series 250 - slow running roll mill

series 250 - slow running roll mill - Slotter – low dust granulation without sieve

The Hellweg ”Slotter” (”Slow Cutter”) type roll mill works without use of sieves and with low speed of just 25 rpm, so that gentle granulation of sprues and gating parts takes place, preventing thermal degradation, ensuring faster output of ground material and regrind with an extremely low level of dust, that is often a decisive criterion to ensure that the material can be returned to the production process.


Extremely fast and easy cleaning is enabled by division of the grinder into two sections.
