Impact mills have a moving impactor that pulverizes a sample through repetitive motions. Ball or ballmedium. The ball mills grind through impact of a grinding media such as balls, rods, etc. Vibratory or shaker. These mills use high speed vibrations and grinding media to combine multiple grinding forces to reduce materials to fine powders.

The ball ring mill has a mill housing, a grinding track (6) and grinding balls (7) which are activated by an outside force and run on the grinding track. For each grinding ball a separate pressure mechanism (8) is provided for transmission of the outside force on the grinding balls. Each pressure mechanism has a ball dome surface as pressure surface acting on the grinding balls.
