Abstract. The motion dynamics of the milling bodies in the working chamber of a planetary ball mill is simulated. Numerical data on the influence of the processing conditions in a planetary ball mill (carrier rotation frequency) on the motion trajectory and the energyforce parameters of the contact interaction of the milling bodies between each other and the working chamber wall are obtained.

A planetary ball mill includes a disc and a vial rotating on top of a disc in a planetlike motion (Fig. 1 a). The number of vials or grinding bowls may vary depending on the type of mill but it consists of at least one vial. Since the disc and vial rotate in an opposite direction, the centrifugal forces are also acting in the opposite direction.
