Step 1: Wetting The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.

A slight difference of condition between the two cases, however, is that with dry milling the fluid (air) fills the whole of the mill shell not occupied by the balls, whereas with wet milling the liquid occupies only a part of the mill volume not occupied by the solid charge. This difference would be expected to have some slight effect on the ...

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Grinding mills are specially developed for a vast range of applications including: size reduction of material, wet or dry grinding, and continuous or batch operations. Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a ...

The mill is filled with suitable grinding media, and the space between each of the disks is essentially an individual grinding chamber. As a result, the mill effectively comprises eight grinding chambers in series. The media is set in motion by the action of the grinding disks, which accelerate the media nearby radially toward the shell.
