Universal Cutting Mill

Cutting Mills are used in sample preparation, particularly for elastic, fibrous or soft/tough materials. Important performance parameters are: the feed size, the motor power and speed. Further parameters are the cutting geometry of the rotor, effective area and aperture of the sieve inserts as well as the air throughput to discharge the milled particles. The sample throughput per unit of time and the required fineness of the ground sample is determined by these parameters. If the performance demands are very high or the material is particularly problematical, we offer the Universal Cutting Mill PULVERISETTE 19. In the standard configuration, the PULVERISETTE 19 is supplied with a V-shaped cutting rotor; its cutting geometry results in fewer blockages even when larger or harder materials are processed than with a parallel cutting rotor. It also “draws in” the material better, forcing the material through the cutting gap better than a disc rotor.

The feed size plays a crucial role for bulky materials, in particular electronic scrap, heterogeneous waste, plastics, and plant parts. The maximum feed size for the PULVERISETTE 19 is 70 x 80 mm. Important applications of the PULVERISETTE 19 in addition to comminution of plastic currently include the inspection of secondary fuels in the cement industry (in Germany according to the Technical Instructions on Municipal Waste) or sample preparation for evaluation of RoHS conformity.
