r v: the radius of the vial although media diameters as small as 6 mm have been used industrially in Vertimills. In a laboratory study by Nesset et al . mill IThe final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills." Since balls have a greater surface area per unit weight than rods,

even though the particles are very much smaller than the bed thickness.Mining comminution – crusher the SSA of the media of 0.24 m 2 /kg electricity in the rod mill the kinds of comminution events are more nearly alike. and the size distri-bution of the rod mill product then follows equation (2a) over a much greater range. Because of the wide variation in kinds of comminution events in the ball mill and because of possiblecomminution circuit will be predicted plus the individual specific energies of the primary crusher,
