In phosphate fertilizer production, double roller press granulators have become key equipment for fertilizer granulation due to their advantages of high efficiency, energy saving, and strong adaptability. They are suitable for many types of phosphate fertilizers.
1.Single Superphosphate (SSP)
Characteristics: High water-soluble phosphorus content, but prone to moisture absorption and caking.
Granulation Advantage: Extrusion granulation improves particle strength, reduces dust, and facilitates mechanical fertilizer application.
2.Triple Superphosphate (TSP)
Characteristics: Higher phosphorus content (46% P₂O₅), suitable for phosphorus-deficient soils.
Granulation Advantage: Enhances granule stability, reduces nutrient loss, and improves fertilizer efficiency.
3.Diammonium Phosphate (DAP) and Monoammonium Phosphate (MAP)
Characteristics: High-concentration compound phosphate fertilizers, often blended with nitrogen and potassium fertilizers.
Granulation Advantage: Granules resist moisture absorption and caking, improving storage and transportation convenience.
4.Phosphate Rock Powder and Low-Grade Phosphate Fertilizers
Characteristics: Made by directly grinding phosphate ore, with low solubility.
Granulation Advantage: Extrusion increases granule density, improves slow-release properties, and extends fertilizer effectiveness.
Application Scenarios for Phosphate Fertilizer Extrusion Granulation
Compound Fertilizer Production Lines: Granulating blends with nitrogen and potassium fertilizers to produce NPK compound fertilizers.
Organic-Inorganic Compound Fertilizers: Combining with organic fertilizers to create slow-release phosphate fertilizers.
Specialty Fertilizer Production: Such as controlled-release fertilizers and soil conditioners.
Double roller press granulators have become the ideal choice for granulating phosphate fertilizers. Whether for SSP, TSP, or compound phosphate fertilizers, high-quality granulation can be achieved with these double roller press granulators, boosting fertilizer efficiency.
