  • Ball Millan overview ScienceDirect Topics

    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.
