Abstract. Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size 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.8VLQJ$VSHQ 3OXV6LPXODWRU IOPscience

This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, 5.20 m diameter, and 11.20 m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill’s rotation speeds are mainly constant (14 rpm), and there is approximately a fixed one-year period of changing liners.

When the internal diameter of the ball mill was over 3.3 m, S S was calculated through equality (16) [32]. B was the maximum diameter (50 mm), and D the effective inner diameter of the ball mill (4.916 mm). (16) S S = 1.102 × B − 12.5 D 50.8 (4) The calculation of motor power of ball mill. The media addition was calculated via The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation The effect of ball size on mill performance ScienceDirect

Heat balance calculators. The calculation of the thermical balance of the ball mill is now proposed according 2 methods: The first method, we know the ventilation of the mill + the cement temperature and we want to calculate the water quantity we need to inject in order to get the temperature at mill outlet we would like to have.

When grinding raw meal, the unit power consumption of the vertical roller mill and the roller press is about the same, which is 7-8kWh/t. But the vertical mill is usually slightly higher. The system of the vertical grinding mill is simple and stable.

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named “conscious laboratory 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.cement-mill PDF SlideShare
