The principal parts of a unit pulverizer system that require adjustment and maintenance are the grinding elements, mill liners, primary air fan rotors and liners, piping, burners, and classifiers. Maintenance costs for all types of pulverizers depend on wear life of the components, which varies with the abrasiveness of the coal .

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.

pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.

Though not present in all pulverizer applications, the primary function of the classifier gearbox is to transmit power from a hydraulic or electric motor to rotate a blade assembly that controls the fineness of the coal. The coal then passes through a mesh that consists of 200 holes per square inch, before it is burned in the boiler.
