### Ball Mill Parameter Selection & Calculation Power

2019-8-30 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

2021-11-27 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.
