Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

In coal milling for power stations, a ''closedloop'' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the recirculation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of recirculation loops within a mill system. The situation is further complicated by the ''mill reject
