The VRM components are subjected to severe wear which can increase dramatically when high silica content is found in the raw materials or where mills are grinding slag. It is known that the largest area of energy consumption in manufacturing cement is in the finish milling process.

Product Quality. When VRM was first mooted as an alternative in cement production, one of its seeming challenges was its particle size distribution (PSD). Due to their high separation efficiency and its high circulation factor, VRM tends to produce cement with a steep PSD curve unlike those generated by ball mills.

VRM to Crown operations. When Crown Cement identified the need to increase the cement capacity of its plant in Bangladesh it opted for vertical roller mill (VRM) technology from Loesche. With a range of VRM benefits, total grinding capacity has increased to 11,000tpd and has offered more product versality with local operating conditions in mind.

Cement Vertical Roller Mill. Cement Vertical roller mill (VRM) is mainly used to grind cement clinker into fine powder during cement production, which can also be used to grind various materials such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite etc. Application : Cement Plant, Clinker Grinding Unit, Thermal Power Plant.

the quality of cement obtained from VRM grinding is as good as, or in some cases better than, that produced in a ball mill. In consequence, most of the world's major cement producers now use vertical roller mills for cement grinding with no hesitation.3 Im Zementherstellungsprozess müssen gewöhnlich drei
