• ### Ball Mill

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 particlesize measurement device and sizecontrol cyclones. The ...

• ### MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classifiion system*. A ball mill circuit has two efficiencies because it has two main functions: • The grinding of coarse particles; and, • The removal of the fine particles to make room for grinding more coarse particles in the ball mill. The overall efficiency of the ball mill ...
