Ball mills. in all ore dressing and milling operations, including flotation, cyanidation, gravity concentration, and amalgamation, the working principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. in the chemical and process industries, grinding is an important step in preparing raw materials for subsequent.
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 13 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.
