These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half ...

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.

Vertical roller mills (VRM) have become the standard for grinding raw materials in the cement manufacturing process. ... The material bed between the rollers and the table is thin and it is essential that the rollers and table do...

The VRM is a vertically placed large sized machine which is equipped with some rollers used for grinding raw material. It also consists of one table which is rotated by electrical motor & raw materials are feeded on the table. Due to centrifugal force on the table, raw material goes below the rollers (a gap between roller & table has to be ...
