Rotary drum granulator can process organic fertilizer, compound fertilizer, biological fertilizer and other granular fertilizers. It has an irreplaceable advantage in the production process. The drum granulating equipment series is an essential fertilizer granule making machine for every fertilizer manufacturer.
Rotary drum granulator can rotate the cylinder with small power, and the external part is made of wear-resistant steel, which effectively extends the service time of the equipment. It is supported by the most power-saving supporting wheel bracket, which is made of high-quality carbon steel and can fully bear the weight of the cylinder.
Considering the large friction between the cylinder and the supporting wheel, our factory specially adopts more wear-resistant materials in this part, on the one hand, it can improve the safety and stability of the equipment.
1.Easy to operate with the beautiful shape
2.Uniform product particles;
3.It is convenient to maintain
The main working mode of the drum granulator is wet granulation of pellets. Through a certain amount of water or steam, the crushed materials can be fully chemically reacted after being humidified in the cylinder. Under a certain liquid-phase condition, with the help of the rotating motion of the cylinder, the extrusion pressure between the particles of the materials can be generated to agglomerate into a ball. Steam, gas ammonia or phosphoric acid or nitrogen solution, phosphoric ammonia slurry and heavy calcium slurry are introduced into the drum granulator to complete the chemical reaction and heating compound fertilizer granulation process in the drum, or the cold granulation process of compound fertilizer supplemented with a small amount of water. The materials to be granulated are rotated by the cylinder. Finally, the fertilizer is agglomerated into balls under certain humidity and temperature, and the pelletizing process of NPK fertilizer production line is completed.
