A critical review on energy use and savings in the

01.05.2011· 5.1.2. Vertical roller mill (VRM) The energy used for the actual grinding process depends mainly on the hardness of raw materials and the type of mill used (i.e. ball mill or vertical roller mill). Typically, an electrical motor of the ball mill uses about 14–15 kWh/tonne of raw mix. On the other hand, a VRM motor uses about 7–8 kWh/tonne.
