On the premise of reasonable steel ball ratio of ball mill machine, the steel ball inside the cylinder will be thrown down, rather than falling with the increasing of the rotate speed of ball mill machine. When the rotation rate is increased to a certain level, the useful power will reach the upper limit. At this time, the grinding effect is better and the wear of the ball mill machine is also
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 cyclones send correct-size material on to flotation
