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. It can lower the carbon content of fly ash, and consequently reduce coal consumption. Comparing to static classifier, the ...
