coal mill process

Coal Mill

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 …

Mill operating parameters determine the mill operating window which provides the limits in which a mill best operates, and outside of which constraints are experienced. The mill operating window is plotted using the mill operating parameters, such as drying limit, erosion limit, milling capacity limit, tampering limit, flame stability limit and pulverised coal transport.
