The bio organic fertilizer granulation process is a core link that determines the quality and effectiveness of the finished product.  Several key points need to be carefully controlled during operation, and stable production must be ensured through the coordinated operation of the organic fertilizer disk granulator machine and the disc granualtor production line. First, the moisture content of the raw materials must be strictly controlled, maintaining it precisely within the range of 25%-35%.  Excessive moisture content can easily cause particle clumping and equipment blockage, while too low a moisture content will prevent the formation of compact granules.  At the same time, it is necessary to ensure that the raw materials are fully composted. Uncomposted materials are prone to secondary fermentation after granulation, leading to particle breakage.  The materials should also be crushed and screened to a particle size of less than 2mm, and mixed thoroughly using the production line's mixing equipment to ensure uniform distribution of microorganisms and organic matter, avoiding any impact on fertilizer efficiency.

Secondly, the parameters of the disc granulator should be adjusted reasonably.  Based on the material characteristics, the disc inclination angle should be adjusted to 45°-55°, and the rotation speed should be adjusted to a state where the material can form stable granules. Improper parameters will not only reduce the granulation rate but may also damage the activity of beneficial microorganisms. During the operation of the disc granulation production line, the equipment's working condition should be inspected in real time, and any material blocking the mold holes should be cleaned promptly to prevent component wear and affect production efficiency. After granulation, a low-temperature drying process should be used, controlling the temperature below 50℃ to avoid killing the microorganisms. After drying, the moisture content of the granules should be reduced to 10%-15% to meet storage and transportation standards. In addition, it is necessary to strictly prevent hard impurities such as stones and metals from mixing into the raw materials to avoid wear on the mold and machine parts of the disc granulator. After each shift, the residual materials in the equipment should be thoroughly cleaned to extend the service life of the equipment.
