Huaqiang plant chemical fertilizer equipment rotary drum granulator solves the problem of wall sticking. Fertilizer drum steam granulation production process has greater output flexibility. The drum granulator is cylindrical and has good heat preservation effect. Using steam to increase the temperature of the material during granulation to meet the liquid phase required for granulation can greatly reduce the water content of the material during granulation, reduce the load of the dryer, and increase the output of the whole machine.
The granulation method of the rotary drum granulator, the double roller granulator adopts dry granulation, and the main working method of the drum granulator is wet granulation. After the base fertilizer is humidified by a certain amount of water or steam or gaseous ammonia or phosphoric acid or nitrogen solution in the cylinder, the compound fertilizer granulation process for chemical reaction and heat supply or the cold granulation process for a small amount of compound fertilizer adds water. Under the condition of temperature and humidity, with the help of the rotating motion of the cylinder, the material particles are squeezed and agglomerated into balls.
The improvement of the drum granulator, the drum granulator has a wide range of adaptability to raw material production. It can be used in conjunction with low-solubility and high-solubility materials as required, and can also be used in conjunction with some organic matter and medium and trace elements. In the process of organic fertilizer manufacturing, the wall sticking problem of the drum granulator is relatively serious, which directly affects the movement of materials, affects the ball forming rate and the roundness of particles. In order to solve this problem, we have developed a high lining for the inner wall of the granulator. The active lining of molecular materials solves the problem of material sticking to the wall and plays the role of anti-corrosion and heat preservation.
The drum granulator is suitable for nitrogen, phosphorus and potassium nutrients, and the ratio of nutrient distribution is flexible. It can process high-nitrogen compound fertilizers, various special fertilizers, organic and inorganic compound fertilizers containing more than 20% nitrogen, and can be used in both npk production line and organic fertilizer production lines.
