GRINDING OF CEMENT Closed circuit grinding: mill and separator The most common equipment for cement grinding is a ball mill, a horizontal tubular mill partially filled with steel balls of proper dimensions and rotating on its horizontal axis (figure 1).

Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 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*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm. 7.
