Wet process. In the "wet process" the batch is first processed in slurry form. Milling and mixing can be accomplished in one step such as by wet ball milling. Tile bodies processed as slurries are mixed, dispersed, pumped, sieved, and then spray dried. Processing costs per unit of granulated product are reduced significantly.

Ball mill - Wikipedia

A rock tumbler functions on the same principle. Ball mills are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture.
