How is the conversion granulator granulated?
Rotary drum granulator, the machine is equipped with steam, gaseous ammonia or adding phosphoric acid or nitrogen solution, phosphorus ammonia slurry, heavy calcium slurry, chemical compounding and heating compound fertilizer granulation process in the cylinder; or supplement A small amount of moisture in the compound fertilizer cold granulation process. The material to be granulated is passed through the rotating motion of the cylinder, and the rolling body rotates in the cylinder, and the ball is condensed into a ball under a certain humidity and temperature to complete the ball making process.

What is the key to granulation of the drum granulator?
Rotary fertilizer granulation production is a process of compound fertilizer heat granulation by compound fertilizer equipment. By increasing the temperature of the material and increasing the solubility of the salt of the granulated water system material, the low moisture content can be achieved to meet the granulation requirements of the material. The amount of liquid phase reduces the heat energy consumption of the drying process and improves the production capacity of the drum fertilizer granulator. Therefore, the quality of the granulation performance is the key to determine the yield and quality of the compound fertilizer for drum granulation.

What is the reason for the failure of the granulation of the drum fertilizer granulator?
The time and frequency at which the material rolls in the granulator is the primary factor in determining the sphericity and grain roundness. During the production process, we have encountered granulation failure due to the difference in friction
between the material and the granulator wall.
1. The internal surface smoothness of the drum fertilizer granulator is large, which reduces the friction between the material and the cylinder wall, weakens the strength of the material moving upwards, and the material does not roll, so no particles can be produced. In this case, we can solve this problem by adjusting the rotation speed of the granulator and installing a small copy board inside.

2. The material in the drum granulator is seriously viscous, the friction between the material and the wall of the granulator is enhanced, and the material in the machine is lifted too high, causing the material to fall from the top to the particles formed. Not rounding and too many large particles, we believe that there are two reasons for this situation: on the one hand, the material is too viscous material, in this case we use the process formula to reduce the amount of viscous material to solve; The drum fertilizer granulator is not smooth inside. This situation is solved by changing the internal materials and increasing the finish of the granulator.
