Particle-size distribution - Wikipedia

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.

Assessing cement fineness. In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.

Typical size of contaminants and particles are indicated below. Note that the values varies widely depending on how the products are processed. By example milling corn starch in 30 minutes can reduce the average diameter of starch particles from 10 to 0.3 microns (μm, 10-6 m). Further milling may produce particles even smaller than 0.1 microns.
