Product Description

Superphosphate Production Line with 20,000-100,000 tons/year
Introduction
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.
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.
Advantages
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.
Technology:
(1) Feeding and crushing
Superphosphate with a wide particle size range is fed to the silo on a forklift and sent to the crusher via a belt for crushing.
(2) Granulation
The superphosphate crushed by the crusher is transported to the disc granulator or drum granulator via a belt conveyor for granulation.
(3) Drying
The superphosphate particles enter the single-cylinder rotary dryer for drying, with a moisture content of 6-8%. The particulate matter in the exhaust gas is removed by the bag dust collector and then discharged to the atmosphere.
(4) Cooling
The dried semi-finished superphosphate granules enter the single-cylinder rotary cooler for cooling.
(5) Screening
The materials coming out of the cooler are first coarsely screened, and the coarse materials are returned to the raw material belt conveyor to be used as raw materials again. The materials under the screen pass through the bucket elevator and then enter the screening machine for fine screening. The materials above the screen are regarded as qualified products, and the fine materials under the screen are sent to the feeding belt conveyor as raw materials.
