Single Super Phosphate Plant - Rock Phosphate & Sulphuric Acid Reaction, Fast Slurry Thickening & Multi-stage Gas Scrubbing

We are eminent manufacturer and supplier of Single Super Phosphate Plant in Hyderabad, Telangana, India with following specifications:

Process Description
Manufacturing of Single Super Phosphate is based on the simplest chemical reaction amongst chemical fertilizers. The major raw materials required are rock phosphate and sulphuric acid. The Rock Phosphate contains Tri Calcium Phosphate which is insoluble in water and hence cannot be taken by the plant. The Rock Phosphate is reacted with dilute Sulphuric Acid. The product of reaction is Mono Calcium Phosphate which is soluble in water. This soluble phosphate can be easily consumed by the plants. Rock phosphate is ground very fine ( 93% passing through 100 mesh ). The measured / weighed quantity of Rock phosphates is fed into lead lined & AHR tiles lined mixer, where it is neutralized with dilute sulphuric acid. For making TSP the rock is neutralized with 54% phosphoric Acid . The reaction is very fast in the beginning and the material is fine slurry which thickens quickly. The material is discharged in the den where the material slowly solidifies. The den discharge is fitted with den cutter which cuts the solid cake to powder . The Fluorine based gases are liberated which are sucked by ID fan and scrubbed in multi stage conventional scrubbers & venturi Scrubbers . The material get cured in a few days time. The material is screened for lumps and the powder is packed as PSSP. The product is granulated in the granulation plant.
