Abstract

DC60 (18/01/55) Equipment for mixing and dissolving solid granules or G particles of matter in liquid L soluble in this liquid, but less dense than that of the liquid, and especially for the preparation of chemical reactions. Lfo-uric acid for phosphate digestion Nature in the production of phosphonitrogene fertilizer Which includes Vessel 2, which includes One stirring path A1 capable of conducting solid G granulation to the lower part of the wessel 2 and the second stirring path A2 capable of It produces motion to promote dissolution of various granular parts in reaction mixtures, especially shear motion. Equipment for mixing and dissolving solid granules or G particles of liquid matter L soluble in this liquid, but less dense than that of the liquid, and especially for preparation of sulfo-ureaic reactions for Phosphate digestion Nature in the production of phosphonitrogene fertilizer Which includes Vessel 2 which consists of 1st stirring A1 capable of producing solid granulation G to the lower part of the Vessel 2 and the second stirring path A2 capable of This causes the disintegration to promote the dissolution of various granular parts in the reaction mixture, especially the shear motion.
