Ideal for processing materials with a maximum Mohs hardness of 3

Ideal for processing materials with a maximum Mohs hardness of 3

  • Two pin discs move past each other at high speed
  • Fineness of the product adaptable by adjusting the rotating speed of the discs
  • Convenient to clean by opening the grinding door
  • Materials should not exceed a Mohs hardness of 3
  • No sieve design for smooth discharge and high productivity
  • Dual power available, offering low operating costs with linear speed up to 200 m/s for greater grinding force
How it works

The feeding system feeds the materials evenly into the grinding chamber, exposing them to strong impacts from the high-speed rotating grinding discs. The materials are subjected to various forces, including friction, shearing, and collision between the static disc and gear ring, which leads to the grinding—depending on the properties of different materials, choosing from varying combinations of both discs so that it meets specific requirements for other materials.
