Temperature Reduction for Ball Mill Optimization Lechler
Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

Ball Mills an overview ScienceDirect Topics
Displacement of balls in mill. n = 42.3 D m where D m is the mill diameter in meters. The optimum rotational speed is usually set at 65–80% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of ball size is calculated in millimeters from the equation:

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.
