10-03-2015· The vertical roller mill equipped with an internal classifier is often said to be more energy efficient than tumbling mills working on the same material and the same size step (e.g. Gerold et al., 2012 ). It is long established in the cement industry and gains more and more importance in the industrial mineral and iron ore sectors.

It is characteristic of grinding in vertical roller mills that the energy input to the material per pass between roller and table is small, for which reason a large number of passes are required to obtain the necessary specific energy input to the material. This leads to a very high internal material circulation factor. .
