Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

F80 is the feed size to the primary BM; T80 is the transfer size (prim mill product size), P80 is the final product (cyclone overflow) The F80 is the feed to the primary ball mill. The T80 (is the P80 of the primary ball mill and the F80 to the secondary ball mill circuit) is measured at the pipe departing the primary ball mill.

With ballmill grinding being one of the most energyconsuming techniques, setting the optimal values of the operational and mineralogical parameters for efficient grinding is a key target in mineral processing plants [6,7,8,9,10]. Ball size is one of the key factors of ballmill efficiency [11,12], and may have a significant financial impact .

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW (Toromocho, private communications).

The EF5 factor only applies below 75 µm to ball milling, and a value of 1 can be substituted above that P 80. Combining the Rowland efficiency factors with the threestage Bond equation gives this overall equation for grinding specific energy consumption from a primary crusher product size, F 80, to a ball mill cyclone overflow product size, P80.
