Productivity increase of the vertical roller mill for cement grinding. In Proceedings of the IEEE Cement Industry T echnical Conference, Hershey,P A, USA, 20–24 April 1997.Vertical roller mills are developed to work as air-swept 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.Energy-Efficient Technologies in Cement Grinding IntechOpen
