Description
. I . , Изобретение относитс к техно огйи минеральных удобрений и может быть использовано в гшмической промышленности при произволе тве минеральных неслежйваюиихс порошкообразных и гранулированHbix удобрений дл сельского хоз йства. / Известен способ предотвращени спе жйв емости минеральных удобрений путеМ йокрыти гранул последш Х припудривающи-ми добавками минеральных сопей Cl3 . Наиболее близким по технической сущности и достигаемому результату етс способ предотвращени слеживае- мости минеральных азотсодержащих удоб{эений , путчем опудрйвани гранул последних пирофиллитом в количестве 2,5% от веса удобрени С2 . Недостаток способа - низка адгези припудривающей добавки, сокрашающа . сроки хранени удобреют в неслеживающемс виде. Цепь изобретени - повышение адгезии припудривающей добавки и увеличение срока хранени удобрени в неспеживающемс виде. Поставленна цель достигаетс тем, что припудривающую добавку испопьзуюг в смеси с гонкодисперС1{ым гидрофильным минеральным порошком в соотношении пирофиллит: минеральный порошок 1:1-5, Причем минеральный порошок берут из группы - огарок, глаугсонит, кпиноптиполит , вермикулит. Способ осуществл етс следующим образом . В барабан-смеситель засыпают ЮООг азотсодержащего удобрени (аммиачную селитру, мочевину, нитроаммофоску и т.д.), затем добавл ют минеральный порошок из группы: глауконит, вермикулит, огарок, клииоптилолит и пирофиллит в соотношении пирофиллит:, минеральный порошок 1 : 1-5 в количестве 0,25-1% минеральной смеси. Все перемешивают 58 мин и получают удобрение, опуаренное защитным слоем мш1еральнпых высокодисПерсных порошков; . I. The invention relates to techno-ogy and mineral fertilizers and can be used in the chemical industry under the arbitrary conditions of mineral non-tracking powdered and granulated Hbix fertilizers for agriculture. / There is a known method of preventing the fertilizer fertilization of the paths of the fertilizer with the cover of the granules of the last X by dusting additives of the Cl3 mineral sweats. The closest to the technical essence and the achieved result is the method of preventing the caking of mineral nitrogen-containing comforts, using the method of dusting granules of the latter with pyrophyllite in an amount of 2.5% of the weight of fertilizer C2. The disadvantage of this method is the low adhesion of the dusting additive, shrinking. shelf life is fertilized in an incompatible form. The chain of the invention is an increase in the adhesion of the dusting additive and an increase in the shelf life of the fertilizer in a non-durable state. The goal is achieved by the fact that the dusting additive is used in a mixture with gonkodisperS1 {hydrophilic mineral powder in the ratio of pyrophyllite: mineral powder 1: 1-5, and the mineral powder taken from the group - calcine, glaougsonite, creamy verperalite, vermiculite. The method is carried out as follows. Drug nitrogen nitrogen fertilizer (ammonium nitrate, urea, nitroammofoska, etc.) is poured into the drum mixer, then mineral powder from the group: glauconite, vermiculite, calcine, kliioptilolite, and pyrophyllite are added in pyrophyllite: mineral powder 1: 1 5 in the amount of 0.25-1% mineral mix. Everything is mixed for 58 minutes and fertilizer is obtained, which is surrounded by a protective layer of highly dispersed powders;
Адг8з он 1ые свойства пирофиллита и смесей пироф тлпта с М1шеральными nopoiJiitaMH приведенм в таб . 1.It is the first properties of pyrophyllite and pyrrph tlpt mixtures with M1 seral nopoiJiitaMH given in tab. one.
