What Is The Application of Drum Granulator?

Rotary drum granulator is generally used for fertilizer granulation, especially for large compound fertilizer production lines. The final quality of fertilizer granulation manufacture is guaranteed due to regular particle formation. In addition, it can also be used for various forms of granulation, including hot and cold granulation and the production of high-medium-low concentration compound fertilizer, especially two nutrients compound fertilizer (NP, NK, PK) and NPK fertilizer.

Raw materials with low solubility include calcium chloride, ammonium sulphate, potassium sulphate, potassium chloride, etc.; high solubility are urea, ammonium nitrate, ammonium phosphate, etc. It can also be combined with some organic matter and medium and micro elements as needed.

The Operation Way of Drum Granulator

The main operation way is wet type granulation:

• on one hand, you can admit stream and ammonia gas access, or add with phosphoric acid or nitrogen solution, phosphoric acid slurry, etc., to complete the compound fertilizer granulation process of chemical reaction and heat supply in the cylinder;
• on the other hand, you can choose the cold granulation process of compound fertilizer that takes a small amount of moisture supplement.

The materials required for granulation are agglomerated into balls by the rotating movement of the cylinder, which generates extrusion pressure between the particles at a certain humidity and temperature.
