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.

Aug 06 2015 This will cause the classifier to stop and is known as being SANDED UP. If the speed of the rakes or spirals are too fast too much will be pulled out the top. This will increase the feed to the mill and result in an overload in either the mill or classifier as the circuit tries to process the increased CIRCULATING LOAD.

Dec 31 2018 A classifier plays a crucial role in the cement industry. It is in charge of separating coal that has been smoothened out and is ready to be burned although the coal is still rough after going through the grinding process. It takes a long time to burn coal that is not perfectly processed with a classifier.
