Rotary impact mills are used for fine grinding soft and medium hard materials. The typical fineness area for the median particle size is between 20 and 500 µm. Circumferential speeds of between 25 and 150 m/s are achieved. A version can also be offered in a counter rotating operation with up to 250 m/s.
