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.
