Pigment Grind: How to Efficiently Adjust the Fineness

The Dispersion Process The Dispersion Equipment ... First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

Choosing Laboratory Dispersing Equipment That's Right for ...

Jun 01, 2020  Lab mixers come in different shapes and sizes. For dispersion of small pigment samples, one key requirement for a lab mixer is the speed of the propeller blade. Although variable speed is desirable, for dispersion a blade speed of more than 7,000 rpm is preferred with a high-speed, shear-dispersing blade.
