Operational parameters affecting the vertical roller mill
Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grindingin cement grinding section. In this case problem was, Cement Mill was not performing as per its design parameters. It was a Vertical Roller Mill & is designed for rated capacity 215 TPH but its output was very low so specific power consumption was higher and contributing to loss in terms of production and in turn profitability. 2.1.

A data-driven decision-making framework for online control of vertical
Introduction. Vertical roller mill (VRM) is a type of heavy-duty and energy-intensive grinding equipment for many industries, such as cement, steel and chemical industries. It is used to grind slag, nonmetallic ore and other block and granular raw materials into required powder materials. The fine powders can be used as raw materials The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball mills.The simple and compact vertical mill layout is cost competitive to build and Operational and Maintenance of Cement plant vertical roller mill
