The analysis of individual mill design and operation is complex so, for simplicity we will consider a typical mill layout for one mill type only. As VSMs have come to represent the bulk of the power station mill fleet, the explanation of mill operations will be based on this mill type. Figure 13.2 illustrates the typical key components of a VSM.
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.
