Claims (4)

1. Способ получения гранулированного минерального удобрения, содержащего азот и фосфор, включающий нейтрализацию азотной кислоты газообразным аммиаком, введение фосфатной добавки, содержащей моноаммонийфосфат, упарку нейтрализованного раствора и грануляцию упаренного раствора - плава, отличающийся тем, что в качестве фосфатной добавки, содержащей моноаммонийфосфат, используют гранулированное минеральное двойное удобрение, содержащее не менее 13 мас.% фосфора в пересчете на Р2O5, например, нитроаммофосфат с массовым соотношением питательных веществ N:Р2O5, равным (23±1):(21±1) или (26±1):(13±1), а введение фосфатной добавки осуществляют путем ее расплавления и подмешивания полученного расплава в упаренный раствор - плав.1. The method of producing granular mineral fertilizers containing nitrogen and phosphorus, including the neutralization of nitric acid with gaseous ammonia, the introduction of a phosphate additive containing monoammonium phosphate, evaporation of the neutralized solution and granulation of the evaporated solution - melt, characterized in that as a phosphate additive containing monoammonium phosphate is used granular mineral dual fertilizer containing at least 13 wt.% of phosphorus, calculated as P 2 O 5, for example, a weight ratio nitroammofosfat pita Yelnia substances N: P 2 O 5, equal to (23 ± 1) :( 21 ± 1) or (26 ± 1) :( 13 ± 1) and administering phosphate additive is achieved by its melting and mixing the resulting melt into evaporated solution - swimming 2. Способ по п.1, отличающийся тем, что расплав фосфатной добавки предварительно полностью или частично отделяют от неплавкой твердой фазы.2. The method according to claim 1, characterized in that the melt of the phosphate additive is previously completely or partially separated from the non-melting solid phase. 3. Способ по п.1 или 2, отличающийся тем, что фосфатную добавку вводят в количестве 2-6% в расчете на Р2O5 от массы готового продукта.3. The method according to claim 1 or 2, characterized in that the phosphate additive is introduced in an amount of 2-6% based on P 2 O 5 by weight of the finished product. 4. Гранулированное минеральное удобрение, содержащее нитрат аммония и моноаммонийфосфат, отличающееся тем, что питательные компоненты находятся в массовом соотношении N:Р2O5, равным (31,6-33,8):(2,0-6,0), при этом 0-30 отн.% Р2O5 присутствует в виде дикальцийфосфата.4. Granular mineral fertilizer containing ammonium nitrate and monoammonium phosphate, characterized in that the nutrient components are in a mass ratio of N: P 2 O 5 equal to (31.6-33.8) :( 2.0-6.0), while 0-30 rel.% P 2 O 5 is present in the form of dicalcium phosphate.
