Material granulation process of drum granulator
The main working mode of drum granulator is wet granulation, in which the basic fertilizer is humidified in the cylinder by some water or steam or gas ammonia or phosphoric acid or nitrogen solution, and then chemical reaction and heat supply are carried out; or the cold granulation process of compound fertilizer with a small amount of water is added. Under the appropriate temperature and humidity conditions, the material particles are made by rotation of the cylinder It produces extrusion force and agglomerates into balls.
The fertilizer granulator machine price varies according to specifications and types.
Material granulation process of drum granulator
When the moisture content of the material is between 30% and 40%, the granulation can be achieved, and the water content of the discharge is about 30%. Thus, the drying requirement of the traditional 70% moisture content process is reduced, and the production cost of organic fertilizer is effectively reduced. In the process of granulation, the temperature of 50-65 degrees is generated in the cylinder, which reduces the moisture content of the discharged particles by 5-8 points, thus reducing the drying cost requirements. The npk fertilizer granulator of granulation particles are uniform, smooth, round and high strength, and the forming rate of granules is more than 95%.
