2. Grinding media The grinding media used are, generally, balls and cylpebs. In compartments of coarse and medium grinding are used balls, and in that of fine grinding, balls or cylpebs. In any compartment, sizes of grinding media must be correlated with the size of the material. Between the balls are formed free spaces (emptiness).
