Vertical roller mills are developed to work as airswept grinding mills. Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius® double roller mill, Pfeiffer® MPS mill). Loesche roller mill and Polysius® roller mills are widely applied in cement raw material grinding.

Comminution is applied in all mineral processing plants where mineral liberation is needed for separation and concentration of valuable minerals. The process is energy intensive and is predominantly carried out in tumbling mills which are known to be highly inefficient. Comminution technologies utilised in other industries, such as the vertical roller mill (VRM), a high compression dry ...
