Pfeiffer (MVR 6000C6) technology for raw material and cement grinding respectively. The VRM is a type of grinding mill that combines crushing, grinding, drying, and classification functions into a single compact unit. It operates by rotating a grinding table, equipped with rollers, while the raw materials are fed into the mill from the top ...

In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced. VRMs are more energy-efficient, eco-friendly, and produce a more consistent product compared to traditional grinding mills. They are also more suitable for use in urban areas due to their lower noise level.
