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.
In addition there is heated combustion air fed to the mill to transport the pulverised coal, and the secondary air supply as shown in Fig. 4. Grinding. The grinding function reduces coal fed into the mill into a dust with particles of the size required for combustion. There are two main types of mill in common use: the spindle type and the drum ...
