The present invention relates to a process for producing granulated Triple Superphosphate (TSP) (up to 47% P 2 O 5 total concentration) from natural phosphate and phosphoric acid. This invention takes into account the various parameters that are involved in the kinetics of the attack reaction between the phosphate and the phosphoric acid to give a monocalcium solution.

SSP is also known as ordinary superphosphate and normal superphosphate. It's sometimes confused with triple superphosphate (TSP) production, which results from reacting rock phosphate with phosphoric acid. Agricultural use SSP is an excellent source of three plant nutrients. The P component reacts in soil similarly to other soluble fertilizers.
