Abstract

The invention relates to a device for liquid mixing and dissolution of solid granules or particles of substance soluble in this liquid and having a density smaller than its density, particularly for preparing a sulphouric reagent, which decomposes the natural phosphates, for production of phosphate-nitrogen fertilizers. The device contains a vessel with vertical axis and bottom, mixing means, including the first mixing means for solid granule direction towards the lower parts of the vessel and the second mixing means for creation in the reaction mixture of a motion for granule dissolution, the first means being made in the form of a turbine with inclined straight blades, and the second means, placed into the vessel below the level of the first means, is made in the form of a radial turbine with straight blades.The result of the invention consists in the efficient liquid dissolution of solid granules due to the motion created by the mixing means.
