Ball Consumption In Grinding Mills

A ball mill, a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis,. The overall wear of the steel in the grinding mills occurs as a peeling of the steel surfaces at a constant radial rate per unit time.
