.:. Mill Critical Speed Determination

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. Mill Inside Diameter: Enter the mill diameter inside the shell (excluding liners). Most mill sizes are reported by ...

TECHNICAL NOTES 8 GRINDING R. P. King Mineral Tech

Since critical speed is larger at smaller radii the centrifuging layer gets thicker and thicker as the speed increases until the entire charge is centrifuging and the net power draw is zero. The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge.
