    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 1/4 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed

    The efficient grinding of clinker in a ball mill is subject to closely controlled drum speeds. At rotational speeds above the critical speed of a mill the contents are simply forced against the sides of the drum by centrifugal force with little or no grinding action. The size of the balls is also an important consideration in a cement mill.
