Fly ash classifiers | Fly ash separation | Ultra fine Fly ash
The fly ash is generated at approximately 60% <45 microns, some of which is used for construction. The general highway concrete filler spec calls for 90% < 45 microns. Two RSG MCS-600 classifiers are employed to classify the ash to 90% <45 microns. The system was commissioned in 2009.

In some installations, bottom ash is classified, i.e. separated by size fraction, prior to final discharge from the combustion zone in an attempt to strip the finer particle sizes from the bottom ash stream. Usually these classifiers strip the finer particles by contacting them countercurrently with an air stream.
