Particle-size distribution - Wikipedia

• The log-normal distribution is often used to approximate the particle size distribution of aerosols, aquatic particles and pulverized material.• The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations.

Mesh (scale) - Wikipedia

Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material.For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.

Particle size Distribution D10 is also written as X10, D(0,1) or X(0,1). It represents the particle diameter corresponding to 10% cumulative (from 0 to 100%) undersize particle size distribution. In other words, if particle size D10 is 7.8um, we can say 10% of the particles in the tested sample are smaller than 7.8 micrometer, or the percentage of particles smaller than 7.8 micrometer is 10%.

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.
