The grinding process in the ball mill is due to the centrifugal force induced by the mill on the balls. This force depends on the weight of the balls and the ball mill rotational speed. At low speeds, the balls are at a fall state (Figure 9(a)). As the operating speed increases, the balls reach a higher helix angle before falling and repeating ...

1. Introduction. Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction .During operation, the grinding balls execute motion paths that result in frictional and impact effects.

Planetary Mills are ideally suited for fine grinding of hard, mediumhard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.
