process in coal mill

Coal Mill an overview ScienceDirect Topics

In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop.

Coal-mill optimisation in coal-fired power stations aids

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.
