A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
Due to the different physical and chemical properties and microhardness of the materials (the grindability of materials in raw meals decreases in clinkers), the clinker discharged from the cement kiln must be pretreated to reduce its particle size so as to increase the output and reduce the power consumption of the ball mill.
Cement Ball Mill Efficiency Calculation. Cement ball mill throughput calculation cement ball mill sizing method explanation 1 introduction the bond method is used to size a cement ball mill efficiency correction factors are applied with the bond equation the method is valid both for clinker grinding and for raw materials grinding.
Nowadays, 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 and some measurements were carried out in an existing CBM in a cement plant to improve the efficiency of the grinding process.
Effect of mill speed, particle load, balls load and ball size on energy efficiency factor. Fixing the operational parameters to these optimal values, Table 2 reports the energy efficiency factor for various mass compositions of the …
