Abstract

Согласно настоящему изобретению способ получения гранулированных комплексных удобрений включает смешивание твердых компонентов в течение от 1 до 10 мин с влажными компонентами, полученными путем нейтрализации щелочных компонентов минеральными кислотами в трубчатом реакторе, расположенном в нижней части смесителя. Температуру смеси повышают до 140°С. Водные растворы аммиака, содержащие нитрат аммония, мочевину, сульфат аммония, нитрат кальция, нитрат магния или их смеси, гидроксид калия или соли калия или их смеси применяют в качестве щелочного компонента, а азотную, фосфорную или серную кислоты в качестве кислотного компонента. Содержание азота в гранулированном продукте составляет от 5 до 25 вес.%, а серы до 15 мас.%.According to the present invention, a method for producing granular complex fertilizers comprises mixing solid components for 1 to 10 minutes with wet components obtained by neutralizing alkaline components with mineral acids in a tubular reactor located at the bottom of the mixer. The temperature of the mixture is increased to 140 ° C. Aqueous ammonia solutions containing ammonium nitrate, urea, ammonium sulfate, calcium nitrate, magnesium nitrate or mixtures thereof, potassium hydroxide or potassium salts or mixtures thereof are used as the alkaline component, and nitric, phosphoric or sulfuric acid as the acid component. The nitrogen content in the granular product is from 5 to 25 wt.%, And sulfur up to 15 wt.%.
