Ball Mill Parameter Selection & Calculation Power, Critical Speed
830· 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, Mill Critical Speed Determination SAGMILLING.COM,The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Mill Inside Diameter: Feet Metres. Enter the mill diameter inside the shell (excluding liners).
