Size reduction with Planetary Ball Mills

Planetary Ball Mill. The PM 100 CM operates with a speed ratio of 1:-1 (centrifugal mode). The centrifugal forces pro-duced by the rotation movement the sample and the grinding balls against the inner wall of the grinding jar, where size reduction takes place primarily by pressure and friction.
