These equations are expanded to calculate the mass of the SAG mill contents and the proportion of steel media, ore, and water. 2. Methods for calculating mill filling. Several measurement techniques are available for quantifying mill filling. Some require a mill entry while others can be made from outside of the mill. Counting lifters

Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 30 to 40%. Autogenous milling is typically practiced in association with pebble crushing to improve circuit power efficiency.

imperfect and ore hardness can vary with size, grindability tests are designed to best represent the size reduction of the industrial equipment analysed. For that reason, it is preferable to design a primary ball mill from a rod mill work index rather than a ball mill index, because the industrial mill will operate over a coarser size reduction

The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.
