Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.First Online: 04 July 2023. Download reference work entry PDF.

The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid-'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.In order to help the Vertical Roller Mill (VRM) working stably with higher automation level and lighter labor intensity, an intelligent automatic control system is designed by analyzing the(PDF) Increase productivity of vertical roller mill

Vertical roller mills follow the interparticle comminution principie. They are known for almost 100 years. However mills for high throughput rates havc been developed just in the last 3 decades 64 following the demands of the cement industry, which was installing steadily raising plant capacities [Brundiek, 2000].This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on Analysis and Optimization of Grinding Performance of Vertical Roller
