For several decades the cement industry has successfully utilized Vertical Roller Mills (VRM) for grinding of raw materials and solid fuels. Most recently, this technology has been employed for the comminution of Portland cement, blended cements and slag cements. The VRM offers several benefits compared to the ball mill.
The grinding of the finished cement consumes approximately one third of the total electrical 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.
