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.
