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 ...

The process of grinding the raw mixture and the additives is achieved by a pressure exerted by the rollers on the grinding table. A fan draws gas flow from the preheating tower to feed the VRM as shown in Fig. 2. Then, a second fan located downstream of the mill draws grinded material to the dynamic separator located above the mill.
