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.

If the mill power is controlled in such way that the level is kept within a certain range, then coal grinding will be much more efficient. In the simulation, it is assumed that the optimal coal- grinding level is when the mill power (function of coal depth on the grinding table) is in the range between 350 - 400 kW.
