  • Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.

  • 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.
