Dynamic classifiers: a fine way to help achieve lower

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.
