Fineness of grind gauges - SAGR
Many types of solid materials must be ground or milled into finer particles for dispersion in appropriate liquid vehicles. The physical properties of resulting dispersions, often called “grinds“, depend not only on actual size of individual particles, but also on the degree to which they are dispersed. The fineness gauges is used to indicate the fineness of grind or the presence of coarse particles or agglomerates in a dispersion. It does not determine particle size or particle size distribution.
Grind gauges are used in controlling the production, storage and application of dispersion products produced by milling in the paint, plastic, pigment, printing ink, paper, ceramic, pharmaceutical, food and many other industries. The fineness gauges is a flat steel block in the surface of which are one or two flat-bottomed grooves varying uniformly in depth from a maximum at one end of the block to zero near the other end. Groove depth is graduated on the block according to one or more scales used. The degree of dispersion is indicated in microns or “Hegman“.
The Hegman scale ranges from 0 to 8 with numbers increasing as the particle size decreases.
