However, most of them are concerned with the simu-.
The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result 1 This mill would need to spin at RPM to be at 100 critical speed. Result 2 This mill's.
