Mill Critical Speed Formula Derivation (2 replies) In practice Ball Mills are driven at a speed of 5090% of the critical speed, the factor being influenced by economic consideration. Mill capacity can be increased by increasing speed but there is very little increase in efficiency ( kWht 1) when the mill is operated above about 4050% of the critical speed. read more. formula for critical ...
