Wet Milling vs Dry Milling: The Differences, Advantages, and Challenges
Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing. Once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products.

Milling process technology • Global Milling Industry • BulkInside
Wet milling, also called wet media milling, is a process in which particles are dispersed in a liquid by shearing, impact or crushing, or attrition. Wet milling can be more intensive, but it can reduce a bulk product into more components and finer particles in the micron & submicron (or nanometer) particle size range.
