Why use double roller extrusion granulator for dry powder granulation

The double roller extrusion granulator granulates the powder by dry method. Its treatment device can be disassembled quickly, which is convenient for cleaning and sterilization outside the production facilities of the machine. The pelletizing process of the granulator is completed in the precise pelletizing device. The advanced pelletizing system, unique pelletizing structure design and the dry pelletizing machine greatly improve the yield of NPK fertilizer production process, reduce the secondary recycling processing, and improve the quality and output of production products. The control and confirmation of the production process of the double roller fertilizer granulator can be completed through the execution of operation procedures or manual operation control. After special treatment, the roller skin has strong wear resistance, fatigue strength and corrosion resistance. The side sealing plate of the extrusion granulator is adjusted by the positioning of the screw rod to extend the service life of the side sealing plate. The whole machine is equipped with water cooling circulation system, and the dry pelletizer ensures that the temperature in use is controlled to prevent materials from sticking, discoloration and deterioration due to heat in the process of pressing. The hydraulic system of the double roll fertilizer granulator is controlled by electric control without opening the pressure gauge manually.

Features of double roller fertilizer granulator:

1. The material is compressed by mechanical pressure, without any wetting agent, and the purity of the product is guaranteed.

2. NPK fertilizer production process is short, low energy consumption, less auxiliary equipment and staffing.

3. The dry powder of double roller extrusion granulator can be granulated directly without subsequent drying process.

4. The strength of particles is high, and the increase of bulk density is more significant than other granulation methods.

5. The operation flexibility is large, the scope of application is wide, and the particle strength can be adjusted by hydraulic pressure.

6. Closed cycle operation of the system to achieve continuous production.
