new vertical mills were planned from the outset, but other options would have been possible. For example, clinker could be ground in an existing ball mill and GBFS in a single vertical mill because the advantages are relatively higher for slag grinding than that of clinker grinding. While the use of two vertical mills would improve 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 ...

However, due to the large variances in size, the clinker particles can segregate significantly and cause undesirable fluctuations in the subsequent grinding process.
