Get PriceNov 17, 2012 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 indies optimum mill performance. The mill wear and the power consumption are increased if the 70 value is exceeded.
Get PriceThe fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.
