derivation of critical speed in a ball mill. TECHNICAL NOTES 8 GRINDING R. P. King. Figures 8.5 for the popular mill types. 3 c is the mill speed measured as a fraction of the critical speed. More reliable models for the prediction of the power drawn by ball semiautogenous and fully autogenous mills have been developed by Morrell and by Austin.

    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 shells inside surface. This is the rotational speed where balls will not fall away from the mills shell. Result 1 This mill would need to spin at RPM to be at 100 critical speed. Result 2 This mills.
