1999-8-3 · Rose and Sullivan showed critical rotation speed Nc, to reach the final stage, i.e., centrifugal motion: (1) N c = 1 2π 2g D−2r where D is the inner diameter of a jar and r is the radius of balls. All throughout, they used the critical rotation speed as the constant value for given conditions of ball-mill

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
