Technical Field
[0001] The utility model relates to the technical field of high-sulfur ammonium phosphate product production equipment, in particular to a high-sulfur ammonium phosphate granulation nozzle. Background Art
[0002] To avoid soil sulfur deficiency, sulfur fertilizers need to be applied. However, in the past two decades, farmers have chosen urea and ammonium phosphate, which cannot provide sufficient sulfur for agricultural soils. Although calcium sulfate is currently the main sulfur fertilizer in China, accounting for 70% of China's phosphate fertilizers, its physical and chemical properties determine that it is not economical to use it far away from the manufacturer. Therefore, calcium sulfate is mainly used near the production area. The result of this unbalanced application is that the sulfur supply is sufficient in areas where calcium sulfate is frequently applied, while sulfur deficiency often occurs in areas where calcium sulfate is not applied.
[0003] The existing production process adopts the method of adding phosphogypsum, which requires a large amount of phosphogypsum to be added, has a high equipment load, and is difficult to achieve a high S content. Therefore, a high-sulfur ammonium phosphate granulation nozzle is needed to solve the above problems. Utility Model Content
