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.Closed circuit ball mill Basics revisited ScienceDirect,2013-4-1 · The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%.
