Machines for Particle Size Reduction

Grinding Solutions for Every Application

Our machines and plants for the industrial size reduction are used for a wide range of applications from the production of animal feed, food, wood to the chemical industry.

For the particle size reduction process itself and for dust separation, the system is operated with a suction working with vacuum. Dust explosion-proof designs are just as possible as different materials, e.g. stainless steel.
