energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can ...
mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton. On an overall basis, VRM consumes about 20 % lower specific energy than conventional closed circuit ball mills and is being
Horizontal roller mills use 65-70% of the energy used in ball mills. Roller press (high-pressure grinding rolls): In this technology materials are crushed between two counter-rotating rollers. These rollers are up to 2 m in diameter and 1.4 m long. Roller presses use 50-65% of the energy used in ball mills.
