using mills in coal power station

In coal milling for power stations, a‘closed-loop’ processis used in which therejects fromthe 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. In fact, there are a number of re-circulation loops within a mill system.

    Coal mill optimisation in coal fired power stations aids

    This is all controlled by thecoal 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.
