In the mid-1990s, the vertical roller mill (VRM) was introduced to the cement industry to reduce this energy usage. Besides lowering power consumption, VRMs may improve process capacityThe two-time breakages are far closer to the actual product size distribution. This study investigated a mathematical model for an industrial-scale vertical roller mill (VRM) at the Ilam Cement Plant in Iran. The model was calibrated using the initial survey's data, and the breakage rates of clinker were then back-calculated.A cement Vertical Roller Mill modeling based on the number

Operational parameters affecting the vertical roller mill
A 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. For the sectors above, the VRM is a powerful and energy-intensive grinding However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement.Cement grinding Vertical roller mills VS ball mills
