The mill feed material needs to be free of metal pieces. Higher the metal pieces frequent operation of diverting gate and results in feed variation. [8,12,14] Abnormal feed size and distribution may increase the level of vibration and destabilize the mill. Large feed size in any case will reduce the mill production rate. Excess fines in the feed

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 ...

Ball Mill Breakage Efficiency. Consider a ball mill circuit processing material of a given feed size and at a given throughput rate to a target product size, the latter which once again distinguishes the "fines" from the "coarse" material. The production rate of fines or new product size material can be calculated from the circuit feed ...

A quick glance at Rowland efficiency factors shows that operating a ball mill at conditions other than the optimum will result in an increase in the unit power consumption of the mill, and a decrease in circuit power efficiency. SAG mills, on the other hand, rarely approach the efficiency of a ball mill.
