METHOD OF PRODUCTION OF COMPLEX FERTILISER Russian patent published in 2015 - IPC C05G1/00

Abstract RU 2541641 C1

FIELD: agriculture.

SUBSTANCE: method of production of complex fertiliser comprises neutralising the phosphoric acid and nitric acid with ammonia, followed by mixing with potassium chloride, final ammoniation and granulation in the granulator-ammonisator, and drying the finished product, and neutralisation with ammonia is carried out by mixtures of nitric and phosphoric acids, when added the pulp of magnesium-containing compounds in phosphoric acid, and the ratio of H₃PO₄:HNO₃:MgO is maintained as 1:(0.5-6):(0.025-0.055), and neutralisation is carried out to obtain the pulp with the molar ratio of NH₃ to H₃PO₄, equal to 1.3-1.5, and humidity of 6-8%.

EFFECT: invention enables to create a technology of production of complex wide range fertilisers, with improved physical and chemical properties.
