Our NPK compound fertilizer drum granulation production line can produce many kinds of compound fertilizers such as superphosphate, ammonium phosphate, nitrate phosphate fertilizer, etc. The raw materials of fertilizer equipment are widely adaptable, not only low, medium and high concentration compound fertilizer, organic fertilizer, feed and so on can be produced.
Common problems of NPK compound fertilizer
1Compound fertilizer is easy to harden. The agglomeration problem of compound fertilizers is widespread in all formulated fertilizer products.
2NPK compound fertilizer is easy to be powdered, while BB fertilizer is the most serious in NPK compound fertilizer.
3NPK compound fertilizer granules dissolve slowly. This phenomenon mainly occurs in sulfur-based compound fertilizer.
The quality of NPK compound fertilizer drum granulation production line is good
The NPK compound fertilizer drum granulation production line relieves the common problems of fertilizer from the process treatment.
1 When the water content of compound fertilizer is high, the fertilizer is easy to harden. Compound fertilizer equipment can control the problem of hardening in fertilizer production. In the fertilizer production line, the fertilizer granulates and enters the drying and cooling system. The dryer dries the moisture in the fertilizer, and then the compound fertilizer granules are cooled rapidly to avoid hygroscopicity reaction. Fertilizer particles are then transported into the packaging to isolate contact with the air.
2 At the same time, the raw material formula of the NPK compound fertilizer drum granulation production line can be adjusted, calcium sulfate or ammonium sulfate is added to ammonium nitrate or urea, and mixed to form a double salt, thereby increasing the stability of the compound fertilizer from the production.
3 The coating machine of the NPK compound fertilizer drum granulation production line is coated with a film on the outside of the compound fertilizer particles, and the coating material is selected to be easy to dissolve and harmless substances. The composite fertilizer granules reduce the contact between the particles after being coated by the fertilizer production line.
