Angle In Ball Mill India

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 The
