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 shells inside surface This is the rotational speed where balls will not fall away from the mills shell
Chat OnlineThe critical speed of a rotating mill is the RPM at which a grinding medium will begin to “centrifuge” namely will start rotating with the mill and therefore cease to carry out useful work Ball 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
