Increasing the filling rate increases the probability of the ball grinding the ore and the self-grinding effect of the ore. The filling rate of the wet type lattice ball mill is generally 40-50%, the filling rate of the overflow type ball mill is generally 35-40%, and the filling rate of the dry type lattice type ball mill is generally 25-35%.
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.
