Ball mills are usually operated below the critical speed The critical speed is the speed where mathematically calculated the grinding media would centrifuge out A mill of this size equipped with steel grinding media converts approx 50 kW per m³ of feedstock
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
The point where the mill becomes a centrifuge is called the Critical Speed and ball mills usually operate at 65 to 75 of the critical speed Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns
