| titleOfInvention | Method of producing compound phosphoric fertilizers |
| abstract | The invention relates to the production of phosphorus fertilizers, in particular thermal phosphates, and contributes to simplifying the process by lowering the heat treatment temperature while maintaining the content of P 2 O 5 in a lemon-soluble form in the final product, as well as creating the possibility of using low-grade phosphate concentrate with a content of 19 - 32% P 2 o 5 . According to the invention phosphate concentrate is mixed with potassium nitrate in a ratio of 1: / 1 - 3 / I fused in a muffle furnace at 300 - 350 ° C for 1 h resulting complex phosphate fertilizer increasing in digestibility P 2 O 5 is 5 - 7 times at significantly low temperatures / 350 - 375 ° C instead of 900 - 950 ° C according to the prototype / and using low-grade phosphate concentrate with a content of 19 - 32% P 2 O 5 . 2 tab. |
