Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling its contribution and effect on milling kinetics load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between .

The grinding media to be ground is mixed with iron balls or rods and fed into the mill from one side. As the mill rotates at low speed the grinding media is ground into very fine particles due to the action of balls or rods on the grinding media. The ground products can be collected on other end. Figure 1.1 1 shows the cut away section of a
