TH164030A - Method for the production of granular nitrogen-potash fertilizers. - Google Patents

Abstract

Edit 8/02/2016 The invention can be used in the chemical industry when producing complex mineral fertilizers using ammonium nitrate and potassium chloride. Granular nitrogen-potash fertilizer production was carried out by Mix a strong solution of ammonium nitrate with potassium chloride and ammonia, granulating and drying the mixture. In the granulation process, the resulting aerosol product, was used as a, aqueous solution of magnesium sulphate at a concentration of 24-30% by mass, in the amount which made the content of magnesium sulfate in the product. Finally, based on MgO, there was no less than 0.5% by mass, so the pellet strength was increased and its cohesion during the extended storage period was reduced. By keeping the MgO in the end product at 0.5 to 1.0 percent by mass, minimal intake of magnesium sulphate was achieved. -------------------------------------------------- ------ The crafting can be used in the chemical industry when making complex mineral fertilizers using Ammonium nitrate and potassium chloride Methods for the production of nitrogen-potash fertilizers The granularity was processed by mixing a strong solution of ammonium nitrate with potassium. Chloride and anonium, granulation of mixtures and drying of products. In the granulation process, the resulting aerosol product, was used the same, an aqueous solution of magnesium sulphate with a concentration of 24-30% by mass, in an amount which made The content of magnesium sulfate in the end product based on MgO was not less than 0.5% by mass. Therefore, granular strength was increased. And the cohesion of it during The extended storage was reduced. In addition, by keeping the MgO in the end product at 0.5 to 1.0 percent by mass, the lowest consumption of magnesium sulfate was achieved.
