Solving Wall Sticking Problem of Fertilizer Equipment Drum Granulator
The drum granulator of chemical fertilizer equipment in FPC plant solves the problem of wall sticking. Fertilizer drum steam granulation manufacturing process has large output flexibility. The drum granulator is cylindrical, with good thermal insulation effect. During granulation, steam is used to increase the temperature of materials to meet the liquid phase required for granulation, which can greatly reduce the water content of materials during granulation, reduce the load of dryer and improve the output of the whole machine.
Granulation mode of drum granulator
Dry granulation is adopted for double roll granulator, and wet granulation is the main working mode of drum granulator. After the base fertilizer is humidified with a certain amount of water or steam or gaseous ammonia or phosphoric acid or nitrogen solution in the cylinder, it is a compound fertilizer granulation process for chemical reaction heating or a cold granulation process for a small amount of compound fertilizer. Add water. Under the condition of temperature and humidity, the material particles are extruded into spheres with the help of the rotary movement of the cylinder.
Manufacturing technology of fertilizer drum granulator
Drum granulator has wide adaptability to raw material production. It can be combined with low solubility and high solubility materials as required, and can also be combined with some organic substances and medium and trace elements. In the process of organic fertilizer manufacturing, the wall sticking problem of drum granulator is serious, which directly affects the movement of materials, the balling rate and the roundness of particles. In order to solve this problem, we developed a high lining on the inner wall of the granulator. The molecular material movable lining solves the problem of material sticking to the wall and plays the role of anti-corrosion and thermal insulation.
Drum granulator is suitable for nitrogen, phosphorus and potassium nutrients with flexible nutrient distribution ratio. It can process high nitrogen compound fertilizer, various special fertilizers and organic-inorganic compound fertilizer with more than 20% nitrogen elements.
