Abstract In coal-fired power plant, pulveriser is the first major component, whose performance dictates the total power plant efficiency. Uniform flow rate and desired size fraction at outlet pipes along with higher classifier efficiency are three important measures which decide the pulverizer performance. Optimization of pulverizer at its best operating conditions has been considered as a ...

The air classification of manufactured sand (i.e., fine aggregates from crushed rock with a particle size smaller than about 4 mm) is utilised to separate crushed rock material into a fine particle fraction (filler, 100 mu m). Reducing the filler content of the manufactured sand is especially important for the concrete industry to ensure the rheology of the cement paste. There is an on-going ...
