  • Ball Millan overview ScienceDirect Topics

    Ball mills tumble iron or steel balls with the ore. The balls are initially 5โ€“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.
