The SAG grindability index test

The mill reportedly rotates at 70% of critical velocity (Verret et al, 2011), or 54 rpm (Gonzalez, 2000)There is controversy surrounding the mill rotational speed The calculation of mill critical velocity (V c) is derived from the balance of gravitational force and the centrifugal force acting on a ball, and is given by Eq, after Austin and Concha (1994) (1) V c = 422 (D-d) where D is the ....
