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.
The plant is equipped with seven gravimetric raw coal feeders and seven HP 1103 pulverisers with dynamic classifiers. The gearboxes that run these coal mills are lubricated with extra high-performance gear oils having outstanding extreme pressure characteristics and load-carrying properties Mobilgear 600 XP320 high viscosity oil.

4.4.Classification The circulating air is also used to classify the pulverized coal product prior to carrying it to the burners. The classifier, located on the top of a mill returns the over-size material back to the pulverizer but allows the proper-sized material to pass out of the mill to the burners. classifiers are critical in providing the ...
All coal pipes (and flows to all of the burners from each respective pulverizer) should be balanced and within +/- 2% of the mean flow. Perform a seal air check. Begin the normal pulverizer start sequence. Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty ...

There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels.
pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.
