An energy based comparison of vertical roller mills and tumbling mills
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.
