One potential method is strengthening the internal and external ventilation of the grinder. 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.

A key component of the grinding process in a ball mill is the ball size distribution (BSD), which controls the grinding efficiency, product size distribution, and media wear rate. Higher rotational speeds and relatively small ball sizes produce finer BSDs, whereas lower speeds and significantly bigger balls produce coarser ones [ 71, 110, 148 ...

Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...
