Is a New Pre-Dispersion Milling Process the Key | 2020-03

Mar 04,  · For years, color coatings manufacturers have been using high-shear mixing techniques to try to wet pigments and reduce particle sizes in raw materials before wet milling. The theory is clear. The smaller the bead you can use in the final milling process, the less mass-specific energy is required to create a quality color dispersion. And that means less energy cost for production, and less time
