A GUIDEBOOK TO PARTICLE SIZE ANALYSIS - Horiba

measuring particle size before and after the process. Particle size growth may be monitored during operations such as granulation or crystallization. Determining the particle size of powders requiring mixing is common since materials with similar and narrower distributions are less prone to segregation.

Particle Size Distribution Functions:

The most common particle size distribution is called the log-normal distribution which is based on the Gaussian distribution. A log-normal distribution is natural to a system where particles are formed or broken up in accordance with some power of particle size such as the volume or surface area.
