All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.

Particle Size Distribution Particle size distribution may be determined either by Laser Particle Size Analysis (LPSA) or by conventional sieving. Results are presented as tabulated data and particle size distribution curves. The data is commonly used to support Petrography and well engineering studies.

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.

drying bagasse. A comparison of the particle size distribution of bagasse and beet pulp was evaluated in terms of flu-idization. The size distribution of bagasse particles is from 2 to 10 times broader than the equivalent distribution of beet pulp particles. The mean particle size of the bagasse is 1/3 of the mean size of the beet pulp.
