Control Feed Size. The particle size of the material entering the ball mill is controlled between 25-15 mm (the diameter of the ball mill is different for different feed sizes). Excessive rules will cause the ball mill to have too much fine material during the grinding process and cannot achieve the friction between the material and the material.
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.
