    Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 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 particle-size measurement device and size-control cyclones.

    For the mining industry our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold copper and platinum industries as well as in the lead zinc silver and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding Nov 17 2011 · The contract includes delivery of a 76 000 tonnes per day grinding circuit consisting of two very large SAG mills and two ball mills.
