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.

December 2021. Greek green follies fail…a U-turn back to coal. Until recently, Greece was one of the largest operators of lignite-fired power plants in Europe, but in 2019 the new government took on the goal of shutting down all coal-fired power plants by 2023 and going green by 2030. But that has turned out to be easier said than done.
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
