Characteristics of fertilizer granulator in granular fertilizer production line
Fertilizer granulator machine is a molding machine that can make materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, which is suitable for the large-scale production of cold and hot granulation and high-, medium- and low-concentration compound fertilizers. The main working method is wet granulation of agglomerates. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after the humidity is adjusted. Under a certain liquid phase condition, the rotation of the cylinder can make the material particles Produce squeezing force to reunite into balls.


1. The steam drum granulator has large output flexibility. The drum granulator is cylindrical and has good insulation effect. The steam is used to increase the temperature of the material during granulation to meet the liquid phase required for granulation, which can greatly reduce the production the water content of the material during granulation reduces the load of the dryer and increases the output of the whole machine.

2. By steam heating, the ball formation rate is high, the temperature of the material is increased, the moisture of the material is bottomed after the ball is formed, and the drying efficiency is improved. And the output is large, the power consumption is low, and the maintenance cost is low.

3. The roller granulator has wide adaptability to raw materials, low solubility (normal calcium, calcium chloride, ammonium sulfate, potassium sulfate, potassium chloride, etc.) and high solubility (urea, ammonium nitrate, ammonium phosphate) The raw materials can be used in conjunction with requirements.

4. The problem of wall sticking in the roller extrusion granulator is more serious, which directly affects the movement of the material, and affects the ball formation rate and the roundness of the particles. To solve this problem, the organic fertilizer equipment has developed a lining on the inner wall of the granulator the movable inner lining of polymer material solves the problem of sticking to the wall of the material, and at the same time plays the role of anti-corrosion and heat preservation.
