Oct 23, 2015· 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.

Centrifugal roller mills use the centrifugal force of cylindrical grinding rolls to crush material into a uniform particle size and grind, turning materials into small granules or fine powder. Some of its typical applications include the particle size reduction of coal, glass, gypsum, limestone, and more.

Grinding roller is core part of vertical mill. SYMMEN METAL Casting can provide customized service according to customers'different processing requirements. Besides, it provides finished product manufacturing service for grinding roller including casting, finished machining, surfacing welding, etc.

The pendulum mill consists of a sturdy, cast mill housing and a rotor with a crosshead. The grinding rollers travel at medium speeds on the grinding ring. The arising centrifugal forces crush the grist between the grinding rollers and the grinding ring. Rotating shovels guide the grist from the mill bottom to the grinding zone.
