1. Adjust the speed of the granulator
The speed of the fertilizer granulator directly affects the size and shape of the particles. If the speed is too fast, the particles may become smaller and uneven; If the speed is too slow, the particles are easy to be too large or poorly formed. Therefore, it is necessary to set the speed reasonably according to the characteristics of the material and the demand of the finished product, and find the best parameters through the trial run.
2. Optimize material humidity control
Material humidity has great influence on particle uniformity. Too high humidity will lead to particle adhesion or unstable forming, and too low humidity is prone to loose or irregular particles. In the NPK fertilizer production line, spray humidification or drying process is usually used to ensure that the humidity of the material entering the granulator is within a reasonable range.
3. Adjust the feed amount and uniformity
Feed instability will lead to changes in the pelletizer load, which will affect the particle uniformity. It is recommended to use an automated feeding system to ensure that the material evenly enters the granulator, and by adjusting the conveyor speed, the feed amount matches the production capacity of the granulator to improve particle consistency.
4. Check mold and pelletizing plate Angle
The size of the hole of the granulator mold and the tilt Angle of the granulator plate will affect the shape and uniformity of the particles. After long-term use, the mold may wear and tear, affecting the quality of particles. Therefore, it is necessary to check the mold and pelletizing disk regularly, and change or adjust the Angle if necessary to optimize the particle forming effect.
5. Improve the efficiency of the screening system
Even if the granulation process has been optimized, the efficiency of the screening equipment still determines the uniformity of the final product. It is recommended that the fertilizer production line be equipped with an efficient screening machine to remove too large or too small particles, so that the finished particles are more uniform.
