Wet Milling Process | Custom Milling & Consulting

Wet milling, also called wet media milling, is a process in which particles are dispersed in a liquid by shearing, by impact or crushing, or by attrition. A mill is charged with media (small beads or spheres) and activated by a high-speed agitator shaft to separate the individual particles.
