*⁄* - particle size distribution rod mill bulgaria

3 plotting the particle size distribution when the particle size distribution is very broad it is difficult to represent it accurately on the normal scale. it is often advantageous in that case to plot the frequency against the logarithm of the size rather than the size itself. a comparison between the two is shown in figures 2 and 3.
