Zusammenfassung:This method produces fertilizers for agriculture. It contracts the lasting period of storage maturation, removes the neutralization, and increases productivity. The fertilizer has an enhanced content of P2O5 and a low content of free phosphoric acid.Description : after the chamber maturation, the superphosphatic mass, containing non-decomposed natural phosphate, is subjected to dry mechanical activation and dispersing of the solid phase, meanwhile destroying the superfluous layer of the product from the reaction, after which it is ready for granulation and drying.
