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.

Typical GA dosage rates used during grinding of clinker vary from 0.01% to 0.15% of the manufactured cement mass. After the grinding process, GAs may not preserve their original molecule structures; however, they do remain adsorbed onto the cement particles to entail variations of cement properties whether in the fresh or hardened states.
