Temperature Reduction for Ball Mill Optimization | Lechler US
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.

Best energy consumption
Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal …
