Modeling of a medium speed coal mill
In thermal power plants, medium-speed mills are widely used for grinding coal particles, where hot primary air is used to dry the ground pulverized coal particles (PCPs) in the meantime [8]. However, when moisture in lignite is higher than its designed value, the original drying capacity of coal mills often fails to dry PCPs to a desired level.
