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.

Particles rejected by the classifier are continuously recycled back to the impactors for further reduction. CMS's Air Swept Classifier System has been uniquely designed to produce a narrow particle size distribution. While the mill is in operation, the speed of the classifier can be changed to compensate for rises in differential pressure losses.
