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.

Cement production requires raw materials rich in the oxides CaO, SiO 2, Al 2 O 3 and Fe 2 O 3. Their common abbreviations, in industry and research of cement, is C, S, A and F respectively [2,3,4]. In order to produce Portland cement, raw materials rich in these oxides are mixed and fired at temperatures usually up to 1450 °C.
