Planetary Ball Mill (10 ml - 500 ml)

Planetary Ball Mill has, unlike other similar machines, four positions where up to eight 500 ml grinding jars can be placed. Each grinding jar needs to be filled with a right combination of grinding balls in order to guarantee the best results.
Like in a planetary system the grinding jars rotate on an orbit around the center. This rotational movement is the self-rotation of the grinding container. The resulting centrifugal and acting acceleration forces lead to a strong grinding effect. Furthermore there are forces working according to the Coriolis acceleration. The result is an intensive grinding effect between the grinding balls and the sample.
Depending on the speed ratio different movement patterns of the grinding balls / media can be achieved.
