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;
