See Details >A ball mill efficiently operated performs a wide variety of services. In small milling plants, where simplicity is most essential, it is not economical to use more than single stage crushing, because the SteelHead Ball or Rod Mill will take up to 2 feed and grind it to the desired fineness. In larger plants where several stages of coarse
See Details >Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol. ore and 25 steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
