Description
(54) СПОСОБ ПОЛУЧЕНИЯ КОМШШКСНОГО УДОБРЕНИЯ(54) METHOD FOR GETTING A COMFORT FERTILIZER
II
Изобретение относитс к способу получени комплексных удобрений, представл ющих собой двойные соли фосфата магни и карбамида.This invention relates to a process for the preparation of complex fertilizers, which are the double salts of magnesium phosphate and urea.
Известен способ получени комплексного удобрени путем смешени фосфата карбамида с монокальцийФосфатом при П5-120°С СП.A known method for producing complex fertilizer by mixing urea phosphate with monocalcium phosphate at A5-120 ° C SP.
Недостатком этого способа вл етс высока температура процесса j неуравновешенное соотношение питательных компонентов N:FnO..:MgO 1:7:0.The disadvantage of this method is the process temperature j, an unbalanced nutritional ratio of N: FnO ..: MgO 1: 7: 0.
Наиболее близким по технической сущности и достигаемому результату к предлагаемому вл етс способ получени комплексных удобрений на основе карбамида и фосфатов кальци , при котором монокальцийфосфат ввод т в расплав карбамида в мольном соотношении 1:(1-4) при тщательном перемеишвании полученного продукта в течение 30-35 мин и выдерживают его при температуреThe closest in technical essence and the achieved result to the proposed is a method of obtaining complex fertilizers based on urea and calcium phosphates, in which monocalcium phosphate is introduced into the urea melt in a molar ratio of 1: (1-4) with careful mixing of the obtained product within 30 35 minutes and kept at a temperature of
пор дка 120С. Далее плав гранулируют . В результате получают двойную соль состава ifCO(NH2),.j.Ca ( ). Сумма питательных веществ составл ет 53,6%, соотношение N:PnOc.:MgO 1:1,2:0 Г2.about 120 ° C. Next, the melt is granulated. The result is a double salt of the composition ifCO (NH2), j.Ca (). The amount of nutrients is 53.6%, the ratio N: PnOc.: MgO is 1: 1.2: 0 G2.
Недостатком этого способа вл етс высока температура процес са , при которой возможно образование биурета, токсичного дл растеto ний даже в малых дозах, низкое содержание питательшлх веществ 53,6%, отсутствие необходимого дл роста растений элемента - магни .The disadvantage of this method is the high process temperature at which the formation of biuret, which is toxic to plants even in small doses, is possible, the content of nutrients is low, 53.6%, and the element necessary for plant growth is magnesium.

Цель изобретени - упрощение технологии за счет ускорени процесса и снижени его температуры, а также повышение содержани и расширение ассортимента питательных веществ.The purpose of the invention is to simplify the technology by speeding up the process and reducing its temperature, as well as increasing the content and expansion of the range of nutrients.
