1999-8-3 Rose and Sullivan showed critical rotation speed Nc, to reach the final stage, i.e., centrifugal motion: (1) N c = 1 2π 2g D−2r where D is the inner diameter of a jar and r is the radius of balls. All throughout, they used the critical rotation speed as the constant value for given conditions of ball-mill.

2012-11-26 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 system, with oversize material continuously being recirculated back
