Tower Granulation Production Line:
Working Principles
Firstly, at the top of the tower , raw materials, such as urea, ammonium phosphate, and potassium sulfate are melted, and then those melted materials will be mixed together in a special mixer.
Second, the mixed materials directly go into a drip-forming machine, and this also happens at the top of the tower .
Third, drips are cooled and then solidified while they fall through the rising air current.
Finally, the obtained fertilizer particles are gathered at the bottom of the tower, and after further cooled by coolers and screening, qualified fertilizer will be obtained.
Advantages of Tower Granulation Production line
1. The production line has removed the traditional drying system, which can consume a great deal of energy. So our tower mixed fertilizer plant is energy saving.
2. The heat, produced by urea melting, is fully used. With low water content, the produced material has no need to be dried, thus energy consumption is achieved.
3. The production line has a high granulating rate and almost no return products during the production process.
4. The Final fertilizer granules are round and smooth. With low water content less than 1%, the granules are difficult to agglomerate. And their compressive strength is higher than 30N.
5. The production line can be used to manufacturer the high content of NPK granule fertilizer such as NPK 21-21-21, NPK 20-20-20 .
5. The production line enjoys a good operation environment, and there is no waste gas, waste water, or industrial residues discharged.
