ball mill critical speed formula

SAGMILLING . . Mill Critical Speed Determination

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. The milling of the materials is a very useful procedure in various domains in life as well as in the constructive domain. Click HERE to subscribe to Make it
