Mill Critical Speed Determation The "Critical Speed" for a grdg mill is defed as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's side surface. This is the rotational speed where balls will not fall away from the mill's shell.

Get PriceBall mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be the 60 to 68 percent critical speed range.
