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 complied by the 'mill reject ...
