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
The particle size distribution is calculated by measuring the mass of particles retained on each sieve In doing this it is assumed that shaking the sieve stack induces the particles to fall into the correct distribution This requires shaking the stack for a well-defined, often significantly long, time
