Grinding process within vertical roller mills: experiment and
Abstract. Based on screening analysis, laser size analysis, grindability and rigidity tests of samples collected on line from a cement and a power plant, a simulation of the grinding process in vertical roller mills was carried out. The simulation calculation used a breakage function, B. The results indicate that the breakage function, B, andA cement Vertical Roller Mill modeling based on the number of breakages. Vertical roller mills (VRM) are widely used to grind, dry, and select powders from various materials in the cement, electric power, metallurgical, chemical, and nonmetallic ore industries.

Analysis and Optimization of Grinding Performance of Vertical Roller
Until now, various types of crushing equipment have been developed to meet the requirement of the industry, such as jaw crusher, cone crusher and vertical roller mill i.e., VRM [3,4,5]. Among these devices, VRM plays an important role in cement, accounting for more than 55% of China’s cement raw meal market [ 6 ], and its Cement industry is estimated to account for ~6–7% of anthropogenic CO2 emissions globally. Therefore, the identification of innovative solutions for their mitigation is both a priority and a challenge. The integration of carbon capture and storage technologies into the industrial production process is considered among the most viable solutions for this Frontiers Evaluating the Carbon Footprint of Cement Plants
