| titleOfInvention | Production method of ammonium phosphate sulfate product |
| abstract | The invention discloses a production method of an ammonium phosphate sulfate product. The method comprises the following steps of: producing ammonium sulfate slurry by carrying out a reaction on by-product phosphogypsum of a phosphoric acid device, by-product carbon dioxide of a synthetic ammonia plant and synthetic ammonia; producing ammonium phosphate slurry by carrying out a reaction on by-product raffinate acid of wet-process phosphoric acid purification and the synthetic ammonia; mixing the ammonium sulfate slurry and the ammonium phosphate slurry according to a certain proportion, and adding a proper harmless nutrient regulator, conveying into a granulator/ dryer, spraying the slurry and granulating; breaking, screening and washing a semi-finished product to obtain a qualified granular product of 2-4mm; and adding a colorizing agent and a wrapping agent according to needs to obtain the ammonium phosphate sulfate product. The method producing the ammonium phosphate sulfate product by using the ammonium sulfate slurry and the ammonium phosphate slurry has the following characteristics that the product nutrient is stable, the granularity is uniform, the compressive strength is high, the pressure in the environmental protection aspect of enterprises is greatly reduced, and the cost advantage is obvious. |
