A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill.

Jan 07, 2015· Raw mills usually operate at 7274% critical speed and cement mills at 7476%. Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2**(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.
