    Variables in Ball Mill Operation Paul O. Abbe®

    Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.

    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.
