Coal mill pulverizer in thermal power plants
Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower than 70% mean higher carbon loss and …
