· Abstract: 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 combination of Portland cement, blended cements and slag cements. The VRM offers several benefits compared to the ball mill in regards to operating costs and flexibility.
· Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classifiion and regrinding take place within the body of the mill.
