This document summarizes the study of single super phosphate (SSP) and granular single super phosphate (GSSP). It describes the different grades of phosphate rock, forms of super phosphate, and processes for producing SSP and GSSP. SSP is produced by treating rock phosphate with sulfuric acid in a ball mill and mixers. GSSP is produced by granulating SSP and drying the granules. Both SSP and GSSP are economical fertilizers that can increase crop yields by improving soil properties and plant growth. They are commonly used in developing countries and for standing crops.

Introduction
* India is greatly dependent on Phosphatic Fertiliser.
* In India,Rock Phosphate was discovered in Birmania at Rajasthan
& Jhamarkotra at Udaipur.
* It is most essential for the healthy growth of plants.
* Lab Testing

4. 4
Different grades of PhosphatE Rock
On the basis of Percentage(%) Phosphorus present in rock phosphate
* In India, Blendable grade is use for manufactring of SSP & GSSP.
High Grade
(30%)
Blendable
Grade (25-
30%)
Low Grade
(10-25%)

Process Description
* Phosphate rock firstly feed to Dryer where remove moisture content.
* Dried Phosphate rock pass through Ball mill to make it powder form.
* Less than 3mm particle size or fine particles move forward to
Pre-mixture through Grid Chamber.
* In Pre-mixture,powder mix with water to increase the conversion.
* In Secondary mixture,the product of Pre-mixture mix with H₂SO₄.
* Conversion of SSP from rock phosphate 94%.

8. 8
Advantage of SSP
* SSP helps to improving root growth & development.
* SSP improves aeration & increase water holding capacity of soil .
* Oil content of groundnut or other oil seeds increase.
* SSP increase resistance power of the plants against attack of pest &
disease.

9. 9
Where SSP is to be use?
* Where both P₂O₅ and sulfur are deficient. SSP may be the
most economical way to meet these needs.
* In Developing countries, where the demand is insufficient
production of concentrated Phosphate fertilizer ,SSP is the
most economical fertilizer can be used in the local areas.
* SSP is used as a byproduct of sulfuric acid, where sulfuric
acid can not be used directly.

Process Description
* SSP is feeded to roller drum/granulator where water is sprayed.
* By the properties of surface tension ,the powder SSP converted into
granular form.
* Above soft granular particles feeded to dryer drum having
temperature of 90-120˚C to harden the granular particles.
* Granular particles passes through over size & under size screen for
maintaining similar size product.
* Then final granular goes for packing.

12. 12
Advantage of GSSP
* Dissolves slowly in the water present in the soil so it is
available to the crops for a longer time.
* GSSP used for standing crops so that the granulate product
rolls down to the plant.
* Used in hilly areas,so that soil erosion decrease.

13. 13
Conclusion
* The process is simple , requiring little technological skill and small capital
investment.
* Small SSP & GSSP plants are economical.
* High percentage of utilization of capacity.
