How does grinding roller work?

The special working and functional principles make every roller mill operate with a great flexibility. The material to be ground is crushed between the rotating grinding track and the individually guided grinding rollers.

Grinding is carried out primarily through the application of compressive force vertically, the secondary effect being the horizontal shear force.
