• ### 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. Result #2 This mill s

• ### Thesis

Critical behavior similar to a phase transition is observed in the entropy mean energy and energy fluctuation. From this another definition of the critical speed is introduced. The critical speed of the mill is defined as the speed about which the entropy mean energy and energy fluctuations exhibit critical behavior.
