A data-driven decision-making framework for online control
202051 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
Operational parameters affecting the vertical roller mill
201741 Abstract. 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
Thermodynamic Performance Analysis of a Raw Mill System in a Cement
