When wetmillsare used, fineness values in the submicron range (>1 µm) can be achieved. Thesemillsare equipped with grinding media (balls, grinding beads) for the grinding process. The bed of grinding media is set into motion by an agitator or by the rotation of the grinding chamber itself. As a result of this, relative movements take place between the grinding media and the feed material introduced into themill…
