TH34600B - Equipment for mixing and dissolving solid granules in liquids, especially in the production of phonitrogene fertilizers - Google Patents

Abstract

DC60 (18/01/12) Apparatus for mixing and dissolving solid granules or particles G of matter in liquid L, soluble in this liquid but less dense than that of liquids, and especially in preparation for slurry reactions. Pho-Eureic for Phosphate Digestion Nature in the production of phosphonitrogenus fertilizers which includes Vessel 2, which includes First stirring path A1 capable of inducing solid grain convection G to the bottom of Vessel 2 and second stirring path A2 capable of inducing solid grain convection G to the bottom of Vessel 2, and second stirring path A2 capable of inducing granular solids G to the bottom of Vessel 2. This creates a movement to promote dissolution of the granular parts in the reaction mixture, especially the shear motion. Apparatus for mixing and dissolving solid granules or G particles of matter in liquid L, soluble in this liquid but less dense than that of liquids, and in particular preparing sulfo-ureic reactions for Digested Phosphate Nature in the production of phosphonitrogenus fertilizers This includes Vessel 2, which includes First stirring A1 capable of inducing a solid granule G to the bottom of Vessel 2 and second stirring path A2 capable of inducing a solid granule G to the bottom of Vessel 2 and a second stirring path A2 capable of This causes the displacement to promote the dissolution of the granules in the reaction mixture, especially the shear motion.
