sized material is not re-entrained into the air and coal stream entering the classifier. PERFORMANCE Classifier technology in the Power Industry has improved significantly with the advent of rotating classifiers. Compared to mill operation with a static-type classifier, the SLS clas- sifier offers a number of performance advantages.

detecting classifier-coal mill damage using a signal vibration analysis 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.

To summarize the coal mill controls, ... 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 .
