Because the NPK compound fertilizer raw material has certain corrosiveness, the inner wall of the cylinder is easy to be corroded, thus shortening the service life. And the viscous material is easy to adhere to the inner wall, reducing the granulation efficiency.
Drum granulator is one of the key equipment in NPK compound fertilizer industry, which is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizer. The main working mode is wet granulation. Through a certain amount of water or steam, the basic fertilizer can be fully chemically reacted after being humidified in the cylinder. Under a certain liquid phase condition, with the help of the rotary movement of the cylinder, the extrusion force between the material particles can be produced to agglomerate into pellets.
The drum granulator produced by our company is welded with high-quality medium carbon steel plate, with built-in special rubber lining or acid resistant stainless steel lining, which realizes automatic scar removal and tumor removal, cancels the traditional scraper device, and achieves the purpose of this machine through strict quality control and special process requirements.
The main advantage of the drum granulator is that it uses steam to heat the humidity, which increases the temperature of the granulated material itself, reduces the granulation moisture, reduces the load of the dryer, and improves the work efficiency. The pelletizing rate of the drum pelletizer can reach 70%, and the equipment is easy to operate, flexible in work, and easy to maintain.
