| titleOfInvention | Method of producing granulated double superphosphate |
| abstract | This invention relates to a technique for producing granular double superphosphate used as a mineral fertilizer. The aim of the invention is to increase the degree of phosphate utilization and to improve the quality of the product by reducing the internal free acidity of the granules. According to the proposed method for producing granulated double superphosphate, including decomposition of phosphate by phosphoric acid at 65-95 ° C, granulation of the pulp by spraying it in a stream of flue gases with a temperature of 800-950 ° C to the area of the pulping spray on the surface recirculating dispersed superphosphate particles and neutralizing the excess free acidity of superphosphate by introducing a neutralizing additive, the pulp is cooled to 30-55 ° C before spraying, and the neutralizing additive is introduced into recirculating dispersed particles. Particles of superphosphate before feeding them into the spray zone. 30-100%, preferably 50-80% of the total amount of neutralizing agent is fed to the processing of the recycling dispersed particles. 1 hp f-ly, 2 tab. with S (L to 00 00 - |
