The coal is pulverized to a fine powder, so that less than 2% is +300 micro meter (μm) and 7075 % is below 75 microns, for a bituminous coal. This system has many advantages such as ability to fire varying quality of coal, quick responses to changes in load, use of high preheat air temperatures etc.

A 100mesh screen has 100 openings per inch, and so on. As the number indicating the mesh size increases, the size of the openings and thus the size of particles captured by the screen decreases. Higher mesh numbers = smaller particle sizes. It is very important to remember that mesh size is not a precise measurement of the mesh opening size.

In granulometry, the particlesize distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
