METHOD FOR PRODUCTION OF COMPLEX FERTILIZERS Russian patent published in 2003 - IPC

Abstract RU 2196758 C2

FIELD: fertilizers. SUBSTANCE: invention relates to a novel, in particular so called multisuspension method for production of fertilizers. According to method, two or several differently composed suspensions of starting materials are prepared in in-parallel- connected separate reactors or reactor systems, and resulting suspensions are fed into granulator either separately or combined with each other immediately before granulation, the first composition consists essentially of neutralized phosphoric acid. EFFECT: increased percentage of water-soluble phosphorus in fertilizer and improved physicochemical characteristics of product. 6 tbl, 4 ex
