International ClassB01F 015/02AbstractA prewetting apparatus for mixing dry material with a liquid before mixing. The wetting apparatus has a cylindrical upper chamber mounted above a lower mixing chamber. The lower mixing chamber has a conic surface with an outlet below. Pressurized liquid is introduced from a housing which extends circumferentially about an upper portion of the lower section. Liquid is introduced through apertures into a groove at the upper edge of the conic surface at a predetermined flow rate and pressure so as to swirl helically down the conic mixing surface to exit at the outlet. Dry particulate matter is metered through an inlet formed in the upper cylindrical portion and is dropped at a predetermined rate into the liquid swirling in the mixing section.Other References
