Dynamic forces include ring gear teeth forces and grinding process forces. When the mill is in operation, the material to be ground and the grinding elements are lifted by lifters on the mill lining and by frictional forces until they fall back, of their own weight. The centre of gravity of the material in the mill is thus displaced laterally.
