Critical Rpm Of Ball Mill Critical Speed Ball Mill
The 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 of critical speed
