Derivation Of Critical Speed In A Ball Mill

critical speed of ball mill formula derivation

critical speed of ball mill formula derivation

In practice Ball Mills are driven at a speed of 50-90% 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 (i.e kWht -1 ) when the mill is operated above about 40-50% of the critical speed
