Comminution costs constitute mainly electricity, grinding balls and liners. Of these three components, grinding balls form the major portion of the consumable costs, and can be as high as 40%–45% of the total. As a result, proper grinding ball selection is a key consideration towards reducing mining costs.

Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density;
