Formula For Critical Speed Of Ball Mill. The critical speed and critical speed of the ball mill the critical speed and critical speed of the ball mill are kept at 63% of the critical speed. For the three configurations 1, 2, and 4 shown in the figure, the end face angle varies from 90 to 111 degrees. The height of the lift rod is also shown.

The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the
