Abstract
Single Super Phosphate (SSP) and Dicalcium
Phosphate (DCP) are critical phosphatic fertilizers and feed additives that
play essential roles in agriculture and animal nutrition. This study
investigates the industrial processing methods and analytical characterization
of SSP and DCP at KPR Fertilizers Limited, Andhra Pradesh, India. The research
focuses on optimizing key process parameters including acid concentration,
reaction temperature, and reaction time to achieve desired product
specifications. Experimental analysis was conducted to determine moisture
content, phosphorus pentoxide (P₂O₅) levels, sulphur content, calcium content,
and fluorine levels in both products. Results indicate that SSP contains 14-18%
water-soluble P₂O₅, 12% sulphur, and 21% calcium, meeting A-grade
specifications. For DCP production, optimal conditions were identified at 10%
HCl concentration and 30°C reaction temperature. The study demonstrates that
proper control of process parameters is crucial for producing high-quality
phosphatic products that meet industrial standards. These findings contribute
to understanding the relationship between processing conditions and product
quality in phosphate-based fertilizer and feed additive manufacturing.
