Dry milling is often used to describe three different processes when talking of maize. The first process, stone grinding, is the oldest and is also known as whole kernel dry milling or full fat dry milling. Whole kernel dry milling does not seek to fractionate the maize kernel but to grind it into uniform size particles, usually flour or meal.

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.

Additives for dry milling . During a dry grinding, often only after a short grinding period hygroscopic material tends to stick. A second factor causing this is the static charge respectively adhesive powers of fine particles. Also heterogenic materials– with elements of varying hardness – tend to stick, like for example plant samples or ...
Please notice that dry grinding needs dry materials, so we can't add water or other liquids during the dry milling process. Wet grinding. Wet grinding means that after the ore entered the mill, it will complete the wet grinding under the interaction of grinding medium and ore. Wet ball mill types: (According to the motion characteristics)
