Critical speed is the speed at which the outer layer of balls would centrifuge if they did not slip.

• ### Derive Equation For Critical Speed In Ball Mill

When the ball mill rotates at the critical speed the theoretical trajectory of the charge is such that it would fall outside the shell as centrifuging occur at this stage and the medium is carried around in a fixed position against the shell. The formula to calculate critical speed is given below.

• ### Critical Speed Of Mill Derive

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.
