Feb 15, 2019 · Within the content of this work, sampling campaigns were organized around a cement grinding circuit and each of the three grinding aids at varying dosage rates were tested. Then the ball mill and the air classifier were modelled by using perfect mixing approach and Whiten’s equation respectively
Jan 07, 2015 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
