| titleOfInvention | Phosphor-potassium-nitrogen-containing npk-fertiliser and method of producing granulated phosphor-potassium-nitrogen-containing npk-fertilisers |
| abstract | FIELD: chemistry. n SUBSTANCE: complex nitrogen-phosphate-potassium fertiliser (NPK) contains ammonium nitrate, anhydrous calcium sulfate, potassium dihydrogen phosphate. Mass fraction of total nitrogen from 13-15%, mass fraction of total phosphates in terms of P 2 O 5 from 9-10%, the mass fraction of potassium in terms of K 2 O from 13-15%. The method of producing a complex NPK-fertiliser from a solid phosphate salt, which is a mixture of the fluorapatite Ca 5 (PO 4 ) 3 F and dicalcium phosphate CaHPO 4 ×nH 2 O, where n is from 0 to 2, and the content of fluorapatite Ca 5 (PO 4 ) 3 <F from 27 to 99% includes: a step of decomposing the said solid phosphate salt with a sulfuric acid by a semi-dry method, a step of adding potassium sulfate as a source of potassium, ammonium nitrate as a source of nitrogen, a step of preparing the slink NPK, and granulating and drying step of the finished product. n EFFECT: improving the properties of NPK-fertiliser, increasing the strength of granules, solving the problem associated with the plasticity of granular complex fertilisers, increasing the water solubility of phosphorus contained in the fertiliser, and improving the consumer properties of NPK-fertilisers. n 12 cl, 1 dwg, 3 tbl, 3 ex |
