Particle size indicates how small (or big) a particle is. The unit is usually mm, μm or nm. The particle diameter is the most common parameter usually used to describe particle size. Particle size distribution is characterized as a percentage of the number of particles in a specific size range compared to the total number of the particles.

Any of these term are part of the jargon to describe the pulverizing machine used to bring the particle size of your test sample down to low microns. Finer is better, and under 270 mesh (53 um) is generally fine enough. The basic parts of this vibratory type sample pulverising machine are: steel grinding bowl, ring and puck.
