Wear of high wear resistant grinding balls (59 Rc) in open circuit finish grinding mills. Independent of the chrome-content of the grinding balls, the specific wear rate of the grinding media var ies approximately from 15-110 grams per ton of cement. This depends on the different tempering pro cess of the grinding media.

Abstract: Ball drum mills area commonplace in grinding offerrous and non-ferrous metals, and a cement production in the world. A significant shortcoming of these mills is high specific energy consumption on grinding. A material grinding process in ball drum mills is executed by grinding bodies that move in a transverse section of a mill drum.

First you need the volumetric capacity of the mill, this is the volume of the mill at rest where the ore just reaches the discharge level (often about 1/3 of the internal volume). From this you need to subtract the volume of the grinding media. You now have the unit capacity. Then take the volumetric feed rate of the new ore per time.
