Dynamic classifiers: a fine way to help achieve lower ...

Apr 08, 2004  A better solution is to exchange the static classifier for a dynamic (or "rotary") type. And the latest generation of dynamic classifiers is indeed proving to be a good way of improving the fineness of the ground coal leaving the mill, with the potential to eliminate almost all the coarse fraction (>300 µm) from the supply of PF to the furnace.

Coal Mill - an overview ScienceDirect Topics

From the fluidising zone the ground coal is lifted up inside the Mill Body. Larger particles of coal reach a terminal velocity at which gravity will pull them back on to the Grinding Table for regrinding (Elutriation); • The fine coal particles are transported to the Classifier through a set of Inlet Vanes; •

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.

The rotary classifier can meet the requirements of fineness for coal powder when burning the low-Nox, which is good to environment. When the evenness index of coal powder is increased to 1.3—1.4, without changing the fineness of coal powder R90, the R200 falls down.
