A particle size distribution indicates the percentage of particles of a certain size (or in a certain size interval). These intervals are also called size classes or fractions. A simple example is shown below. Here, a mixture of grinding balls has been separated by size: 5 mm, 10 mm, 15 mm and 40 mm: 5 mm. 10 mm. 15 mm.

Small differences between Small scale mill and MACRO-PACTOR can be observed in the extent of the strongest particle fraction between 1000 m and 1400 m, which lead to a slight shift of the particle size distribution towards coarser particles for the Small Scale Mill. The extent of this small deviation seems to be material specific.

The example below shows a particle size distribution with 5% oversize. Here, 95 % of the particles are below 1 mm, the oversize has a size of 1 - 1.25 mm. This can be quantified by Q3 (1 mm) = 95% or 1-Q3 (1 mm) = 5%. This example also shows that the addition of oversize increases the mean particle size, while the median remains unchanged.
