Mill Critical Speed

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
