3 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 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%)
5 Different Forms of Superphosphate On the basis of Composition & Shape Single SuperPhosphate (SSP) Granular Single SuperPhosphate (GSSP) Triple SuperPhosphate (TSP)
6 Preparation of SSP
7 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 H ₂SO₄. Conversion of SSP from rock phosphate 94%.
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 Where SSP is to be use? Where both P ₂O ₅ 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 .
10 Preparation of GSSP
11 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 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 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 .
