In the modern industry, people find that adding the sulfuric acid into the naturally occurring phosphate can produce an excellent soluble fertilizer – super phosphate. The manufacturing process of SSP involves reacting rock phosphate with sulfuric acid to produce a soluble form of phosphorous, which can be easily absorbed by plants. SSP is an excellent source of the npk nutrients for plant growth. SSP is a relatively cheap high-quality phosphate fertilizer, which is popular in the the regional area for small people needs.

Furthermore, it is a high demand fertilizer as the soil amendment. It contains the 16%-20% P2O5, 18%-21%calcium content and 11%-12% sulfur content. For many fruits and vegetables, the SSP is an indispensable fertilizer. As an organic and compound fertilizer equipment manufacture, we supply the Single Super Phosphate production machine. If you want to set up a single super phosphate fertilizer manufacturing plant, we offer the whole technology and, site planing and the equipment supply.

The first step in the process is to prepare the raw materials required for the production of SSP. This involves crushing and grinding the rock phosphate to a fine powder.

The next step involves mixing the powdered rock phosphate with sulfuric acid in a reactor vessel. The acid reacts with the phosphate to produce phosphoric acid, which then reacts with the remaining rock phosphate to produce Single Super Phosphate.

The SSP slurry obtained from the reactor vessel is then sent to a rotary dryer to remove the excess moisture. The drying process helps to increase the shelf life of the fertilizer.

The dried SSP is then sent to a granulator where it is mixed with other essential nutrients like nitrogen and potassium to produce a complete fertilizer. The granules are then screened and packaged.

If the granulator works 10 hours one day, the min output at least is 20t/h. If you want to granulate in shorter time, you need more larger capacity. The most fitting granulating machine is our rotary drum granulator. The mix output is 30t/h, that’s say, it can granulator 300-400t/d to the maximum. The drum granulator is widely use in the commercial organic and compound fertilizer production. The most common granulator size is 3-6mm. We also can make the different size according to your requirements.

Pan granulator is another granulating machine for organic and compound fertilizer production. Compared with rotary drum granulator, it has a smaller capacity. But it is the most popular granulator in most regions. Its hour capacity is between 0.02t/h to 6t/h. For the owner of the small scale and middle scale phosphate fertilizer plant, our pan granulator is your top choice. In addition, if you want to produce 2000t phosphate fertilizer every year, you can equip with 4 SXYZ-3600 disc granulator for your phosphate fertilizer plant. As for the granulator size, when you regulated suitable material moisture. 1-8mm and can be adjusted according to your meets. The successful granulating rate can be 93%.

By control the moisture: You can control the water spray system to control the raw material moisture. Less water, smaller size; much water, bigger size

By control the pan slope angle: You can regulate the pan slop angle to regulate the final granules size. Sharp slope, smaller size; slow slope, bigger granules.

Compared with disc granulator and drum granulator, the double roller granulator is the most easy machine to granulate. It is an hot selling granulator in the npk and single fertilizer making. First, it can press your single phosphoric powder into spherical particles. There is no need adding water in the process. The final granule size for double roller granulator is 3-10mm. Second, after granulating, there is no need to dry and cool the particles. You can pack them directly.
