• to maximize the rate of delivery of thrown grinding media at the toe of the charge to gain the best milling action, • to avoid liner and ball damage and • to provide an economic liner wear life. Shell liner design is driven primarily by the practical operating experience with various combinations of lifter heights, spacing and angles.

terms of energy requirements and steel consumption related to grinding media and liners. 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
