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 ...

After coal fineness is determined by sieving, fineness data should by plotted against the Rosin and Rammler formula. This plot is utilized to verify the representativeness of the coal sample and sieving. A representative sample will plot as a straight line on a Rosin and Rammler chart. Figure 5 - Plot of coal fineness on Rosin and Rammler
