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
