The material is crushed and torn apart in two or four grinding jars by grinding balls. The grinding balls and the material in the grinding jar are acted upon by the centrifugal forces due to the rotation of the grinding jar about its own axis and due to the rotating planetary disk.
The grinding jar and the planetary disk rotate in opposite directions, so that the centrifugal forces alternately act in the same and opposite directions.
This results in, as a frictional effect, the grinding balls running along the inner wall of the jar, and as an impact effect, the balls impacting against the opposite wall of the grinding jar.The impact effect is enhanced by the grinding balls impacting against one another.Loss-free grinding, even in the case of grinding of suspensions, is guaranteed by a hermetic seal between the grinding jar and the cover.
