Energy-Efficient Technologies in Cement Grinding IntechOpen
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.The mill consists of the lower casing, upper casing, table mounted on the vertical planetary gear reducer and grinding rollers supported by the swing levers. The separator is installed at the upper parts of the mill. The raw material fed through the air lock gate is ground between the rollers and table with the grinding force added byVERTICAL ROLLER MILLS AMCL
