Bauxite. Lead Zinc. Rock phosphate. Metal slag. Coal. There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
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.
