Calculating and Plotting Size Distributions

If the size distribution of particles from a crushing or grinding operation does not approximate a straight line, it suggests that there may have been a problem with the data collection, or there is something unusual happening in the comminution process. The size modulus is a measure of how coarse the size distribution is, and the distribution
