Coal Mill - an overview ScienceDirect Topics

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.
