Claims (6)

1. Способ получения фосфорсодержащих сложно-смешанных удобрений, включающий смешение фосфорсодержащего компонента с соединениями калия в присутствии сульфат-иона, последующее гранулирование и сушку продукта, отличающийся тем, что в качестве соединений калия и сульфат-иона берут K2Mg(SO4)2 и процесс ведут до получения в смеси молярного соотношения P2O5 : K2Mg(SO4)2 = 1 : 0,76 - 4,6.1. A method of producing phosphorus-containing complex-mixed fertilizers, comprising mixing a phosphorus-containing component with potassium compounds in the presence of a sulfate ion, subsequent granulation and drying of the product, characterized in that K 2 Mg (SO 4 ) 2 is taken as potassium and sulfate ion compounds and the process is conducted until a molar ratio of P 2 O 5 : K 2 Mg (SO 4 ) 2 = 1: 0.76 - 4.6 is obtained in the mixture. 2. Способ по п.1, отличающийся тем, что в качестве фосфорсодержащего компонента берут фосфорит или суперфосфат, или фосфаты аммония. 2. The method according to claim 1, characterized in that as a phosphorus-containing component take phosphorite or superphosphate, or ammonium phosphates. 3. Способ по пп.1 и 2, отличающийся тем, что в качестве K2Mg(SO4)2 используют калимагнезию или шенит, или полигалит.3. The method according to claims 1 and 2, characterized in that as K 2 Mg (SO 4 ) 2 use kalimagnesia or shenite, or polygalite. 4. Способ по пп. 1-3, отличающийся тем, что на смешение дополнительно вводят серную кислоту. 4. The method according to PP. 1-3, characterized in that sulfuric acid is additionally introduced into the mixture. 5. Способ по пп. 1-3, отличающийся тем, что весь K2Mg(SO4)2 вводят на стадию смешения или 5 - 10% от общего его количества добавляют на стадию гранулирования в виде раствора и гранулирование ведут при 70 - 90oС.5. The method according to PP. 1-3, characterized in that all K 2 Mg (SO 4 ) 2 is introduced into the mixing stage or 5 to 10% of its total amount is added to the granulation stage in the form of a solution and granulation is carried out at 70 - 90 ° C. 6. Способ по пп.1-3, отличающийся тем, что при подаче всего K2Mg(SO4)2 на стадию смешения на гранулирование дополнительно подают плав или раствор нитрата аммония.6. The method according to claims 1 to 3, characterized in that, when all K 2 Mg (SO 4 ) 2 is supplied to the mixing stage, a melt or a solution of ammonium nitrate is additionally fed to the granulation.
