Particle Size Distribution - D10, D50 & D90 - Sieve Analysis

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.

The number of sieves used for a given determination depends largely on the reason for making the determination. If, for example, the only information required is the percentage of material less than a given size, a single screen is sufficient. If a particle size distribution must be obtained, five sieves is often a satisfactory number.

Particle Size Distribution Functions:

The particle-size 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.
