  • Coal PulverizerPall

    Coal PulverizerPall

    Mechanically pulverizing coal into a fine powder enables it to be burned like a gas thus allowing more efficient combustion. Transported by an air or an air/gas mixture pulverized coal can be introduced directly into the boiler for combustion. There are several pieces of equipment involved in processing coal to be burned in this fashion.

    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. In fact there are a number of re-circulation loops within a mill system.
