<p>The invention relates to the methods for producing nitrogenous-potash granulated fertilisers based on carbamide and potassium chloride. The method consists in the following: potassium chloride is mixed with carbide in a blender, the mixture heated and granulated. For mixing 1.66-9.9 mass. %, of chloride potash is chosen of and carbamide is fed into the blender in the form of a fusion cake. Granulation is performed by means of prilling in the gas flow inside a granulation tower. The nitrogenous-potash fertiliser produced in this way comprise K2O 1-5.94 mass. % and N 41.4-45.2 mass. %.</p> |
