A cement Vertical Roller Mill modeling based on the
Matrix model's results model provides a more robust prediction based on the number of 2-times clinker breakage in VRMs (R = 0.9916, MSE = 5.3526, accuracy = 94.6474). Also shown by the results of the matrix modeling, the S increased with decreasing the particle size. In contrast, the population balance model increased with increased Two mill systems are employed for most coal grinding applications in the cement industry. These are, on the one hand, vertical roller mills (VRM) that have achieved a share of almost 90% and, on(PDF) The latest innovative technology for vertical roller mills

CEMENT SikaGrind® FOR VERTICAL ROLLER MILLS
In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.Roller presses have become well established as a method for increasing the capacity of finish grinding ball mill circuits. While other competing technologies exist, notably the vertical impactor, the vertical roller mill, and most recently the Horomill, none of these has become common in North American cement plants.
