How to Calculate the Coal Quantity Used in a Power Plant ...
Coal trader's web sites give base prices in the international market. We take a coal price of around 65 $ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 $ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

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.
