EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

2021-3-26  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 media shape and mill power.

The major extrinsic factor that has a huge effect on the milling efficiency is the quality of grinding media. The use of inferior grinding media does not only compromise the milling efficiency, but also comes with a cost penalty due to the premature breakage of balls in service. Steel grinding media fail if there is a significant variation in chemical composition, hardness and microstructure of the balls.
