Superphosphate, also known as ordinary superphosphate, or superphosphate for short. It is made by decomposing phosphate rock with sulfuric acid or sintering calcium carbonate and phosphate rock. It is usually in powder or granular form and can be used as raw material for phosphate fertilizer and compound fertilizer.
Compared with powdered superphosphate, granular superphosphate is less likely to react with soil and is easier for plants to absorb, increasing fertilizer efficiency.

1. Reduce the contact area between phosphorus and soil and reduce the chance of phosphoric acid being fixed in the soil.
2. Convenient for mechanical application and improve work efficiency
3. After passing through the dryer and cooler, the particle shape changes greatly and the morphology is better.

Our company's granular superphosphate production line uses the crystallized product of the reaction between phosphate rock and sulfuric acid, ground to 99 mesh, concentrated and filtered as raw material. The particle size of the raw materials is less than 3mm when they are first produced. They will agglomerate during storage and transportation. The particle size distribution range is wide, the moisture is 13%, and the pH value is 3.5.
