When drum granulator works, the inner shell is filled by steam, ammonia gas or phosphoric acid or nitrogen solution, phosphmidon slurry, heavy calcium slurry, and then compound fertilizer is granulated under the chemical reaction and heat supply. Or it can add some water to finish the cold granulation. The material to be granulated can rotate along the shell's rotation, and be conglomerated into pellet under certain humidity and temperature.

       Drum granulator features:

       1. Granulation rate can reach 70%, with less return material. With small size, the return material can be reused for granulation.

       2. Heated by steam, the material temperature is increased with less water, so as to enhance drying efficiency.

       3. Taking engineering plastics as inner lining, the material can prevent adhering to the shell, and it can guarantee corrision resistance and keep warm.

       4.Large capacity, low energy consumption and less maintenance cost.
