    SAGMILLING.COM . . Mill Critical Speed Determination

    Mill Critical SpeedDetermination. The "Critical Speed" for a grinding mill is defined as the rotationalspeedwhere centrifugal forces equal gravitational forces at themill shell'sinside surface. This is the rotationalspeedwhere balls will not fall away from themill's shell. Result #1: Thismillwould need to spin at RPM to be at 100%critical speed.

    What is a Cement Mill (with pictures)

    The efficient grinding of clinker in a ballmillis subject to closely controlled drum speeds. At rotational speeds above thecritical speedof amill, 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 acement mill.
