coal mill dynamic classifier motor size

Dynamic Classifier Loesche

Efficient classification is particulary important in power station applications; a steep product particle characteristic curve ensures that optimum combustion is achieved in the boiler while keeping emission rates at a low level. Loesche dynamic classifiers can be fitted to any type of coal mill.

Dynamic classifiers: a fine way to help achieve lower

Apr 07, 2004· 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.
