UA50392U - Method for the preparation of mineral fertilizer - Google Patents

Abstract

A method for the preparation of mineral fertilizer, comprising the use of ash from burning of organic residue, which is passed through pelletizer, dampened by water spraying, dried and formed pellets from the obtained mass, besides the obtained from burning of organic residue ash is sieved through separator of 2-, dampened by water spraying to the level of 16-24 % and pellets are obtained by forming on screw pelletizer-extruder with the use of matrix with holes of 4-, besides at the output of mass from matrix channels, it is given to the action of hot air mass to the prevention of adhesion of formed mass and dried to the dampness of 5-3 %, after that the dried formed mass is milled on milling machine of roll type for the preparation of cylinders of length to , after that the milled mass is separated for the sifting of dust and small particles.

Description

a slurry of granules obtained by agglomeration into granules is poured to moisten the ash before its formation. (see table 1). This makes it possible to widely use

The method is carried out as follows: the ash of the obtained mineral fertilizer is sifted through a sieve of 2-4 mm, then moistened, the efficiency of its use is much higher by spraying water to the level of 16-2595 from the mass of ash, in soils with insufficient moisture. Thus, it is mixed to a homogeneous mass and fed into a screw, mineral fertilizer is proposed, a slag granulator-extruder for mass formation and its formation on a screw granulator, through a matrix with 4 mm holes. At the exit of the mass, which is obtained without addition and/or with addition, from the channels of the matrix, it is immediately exposed to the action of hot chemicals: macroelements, air, to prevent the formation of microelements, growth stimulants from sticking together. And these masses. After that, the formed mass is directed to different chemical substances added to the fertilizer for drying. Dry to a moisture content of 5-3905. Then, by washing: the dried formed mass is crushed into small pieces - by adding to dry ash, for this, cylinders of the roller type are obtained, and cylinders are obtained, macroelements, microelements and sti- with a length of no more than bmm. and separate the dust and small remains, turn it into a mass of ash, which goes to the off-loader to obtain clean granules in diameter and length - the conveyor before it is moistened; no less than BMM. This is how we got aligned grains - by dissolving a certain amount of ingredients, which are placed in water and stirred for 5 minutes. on them chemicals in the water, which is sent to the laboratory rotator, after which they check the moisture of the ash before its formation; the content of K2O in the aqueous solution was 20.295. - also by combination, chemicals

This shows that the rate of transition of potassium from gradation to dry ash and to water, which is sent to the voids obtained by formation, is significantly due to the moistening of the ash before its formation;

The strength of the obtained granules is up to 0.7 kg - the increased moisture content of the mass before the granule is formed. The bulk density is up to O0.9 kg/l, which reduces the load on the working organs, and the flowability is 10095. The content of KgO is 10-ruder, which reduces their wear. 4095, P2O5 - 1-1295, also contains Ca, Mo, 5, Cy, Thus, according to the proposed method

Mp and other trace elements. we get a complex mineral fertilizer,

The obtained mineral fertilizer by forming cylindrical granules for forming on a screw granulator has the following screw-type granulators - extruders without any advantages compared to granules obtained by giving and/or with the addition of other chemical methods by agglomeration on blade granulators: copper ( macroelements, trace elements, stimulators - increased porosity, which in turn are growth stimulators, etc.), which has porosity and increases the solubility of the fertilizer and expands the possible leveling, which ensures high solubility and its application and effectiveness; uniformity of its introduction into the soil. Speed - better alignment of the granules, which improves the transition of potassium from the granules obtained by fo- uniformity of introduction into the soil; rmation, much higher than that of granules obtained - increased moisture content of the mass before forming by agglomeration. This makes it possible to expand, which makes the technological process of more sustainable use of the obtained mineral flour, and less dependent on the aggregate state of the raw material, ensures a much higher efficiency of its raw materials; application in soils with insufficient moisture.
