· Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.

Chat OnlineBall Mill Critical Speed

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
