With earlier planetary ball mill designs, the kinematics of the mills were always perfected to ensure an optimal launching point for the grinding elements as learned from the conventional ball mills. The grinding drum of a ball mill functions in earth's gravity field, whereas the movement of a ball in the planetary ball mill is due to the superposition of various centrifugal and coriolis forces.
Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating.
