Hegman gauge - Wikipedia

A Hegman gauge, sometimes referred to as a grind gauge, grind gage, or grindometer, is an instrument which indicates the fineness of grind or the presence of coarse particles and agglomeration in a dispersion. It is commonly used to determine how finely ground the particles of pigment (or other solid) dispersed in a sample of paint (or other liquid) are.

Pigment Dispersion and Stabilization in Paints and Coatings

Pigment dispersion can be a challenging process during the production of paints, coatings, and inks. Waterborne systems are particularly challenging due to environmental regulations, demand for premium color coatings, and cost considerations. Moreover, the quality of the dry paint film or ink is very much related to the uniformity of the distribution of the pigment.

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.
