Ball Mill an 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.

Exponential increase in the demand of steel all over the world is leading to rapid depletion of the high grade lump iron ore, leaving the low grade iron ore as fines. Hence industries are forced to use low grade iron ore fines by beneficiating it which produces desired high quality ore required for blast furnace. The fines are subjected to the communition like crushers and mills as the
