May 20, 2005 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.
seem to be attractive in terms of costs. That may be true in terms of capital investment.large capacity energy saving ball mill . But when examining the service period and operating costs of the various grinding systems, the VRM has operating advantages over other grinding systems. Ball mills, for example, need up to 40% more energy during the grinding process compared to Pfeiffer VRMs.
