Simulator which has a robust data library and powerful engineering calculation capabilities. The simulator was used for the thermodynamic performance of a raw mill (RM) and raw materials preparation unit in a cement plant in Nigeria using actual operating d ata. The raw mill has a capacity of 240,000 kilogram material per hour.
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.
