METHOD FOR PRODUCING NITROGENOUS-POTASH FERTILISER |
摘要 |
<p>The invention relates to methods for producing nitrogenous-potash granulated fertilizers. The inventive method consists in the following: potassium chloride is mixed with ammonium nitrate, the mixture is granulated in a granulating drum. For mixing ammonium nitrate is taken in the form of a fusion cake and 0.5-3.2 mass % of magnesium sulphate is added to the mixture. 37-60 mass % of chloride potash is chosen for mixture. A mass ratio of nitrogen in the mixture upstream from the granulating drum and in the final product is maintained in the range of 1.005 to 1.05. The nitrogenous-potash fertilizer produced in this way comprises (mass %): N 12-25, K2O 16.6-40.</p> |
