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 applies artificial gravitational force to the grinding medium by using a centrifugal force field. In a planetary mill, the grinding jar rotates around its own axis in a direction opposite to the direction of support plate rotation, which causes a nonuniform field of centripetal acceleration.

Grinding in Ball Mills: Modeling and Process Control

Grinding in Ball Mills: Modeling and Process Control

The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.
