Performance optimization of an industrial ball mill for

The ball mill consumes about 25-30% of the total energy in the beneficiation plant, and hence any improvement will improve the overall economics of the plant. The power consumption of the ball mill was monitored for two months, and the data is shown in the histogram in Figure 2c. It can be seen that the power consumption for each shift variedNowadays, ball mills are used widely in cement plants to grind clinker and gypsum to produce cement. In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed andEnergy and exergy analyses for a cement ball mill of a
