This formula calculates the critical speed of any ball mill. Most ball mills operate most efficiently between 65% and 75% of their critical speed.
ABSTRACT: In this study, the effect of fraction of mill critical speed was investigated on the limestone and the clinker samples using Göltaş cement factory (Isparta/Turkey) at batch grinding conditions based on a kinetic model. For this purpose, firstly, six different mono-size fractions were
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
Estimates the critical speed of a grinding mill of a given diameter given the mill inside diameter and liner thickness. If given a measured mill rotation (RPM), then the mill`s fraction of the critical speed is given

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell.
