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.

Jan 10, 2012 Triple superphosphate: Two processes have been used to produce triple superphosphate: run-of-the-pile (ROP-TSP) and granular (GTSP). GTSP yields larger, more uniform particles with improved storage and handling properties than ROP-TSP. Most GTSP material is made with the Dorr-Oliver slurry granulation process.

Triple Superphosphate Triple superphosphate (TSP) was one of the first high-analysis phosphorus (P) fertilizers that became widely used in the 20th century. Technically, it is known as calcium dihydrogen phosphate and as monocalcium phosphate, [Ca(H₂PO₄)₂ .H₂O]. Despite its excellent history as a P source, its use has declined as other P fertilizers have become more popular.

In many other parts of the world it is more cost effective to use triple superphosphate fertiliser. In this process phosphate rock is reacted with phosphoric acid to produce a product with 21% phosphorous. Triple superphosphate plants are more capital-intensive but with a more concentrated product these plants can service a greater area.

variable particle size produced in a manner similar to normal superphosphate. Wet-process phosphoric acid (50 to 55 percent P 2 O 5) is reacted with ground phosphate rock in a cone mixer. The resultant slurry begins to solidify on a slow moving conveyor en route to the curing area. At the point of discharge from the den, the material passes ...
