The granulation rate of the disc granulator directly affects the production efficiency and quality of organic fertilizer. When processing organic fertilizer raw materials containing high fiber and impurities, the disc granulator can take the following measures to ensure the uniformity and granulation rate of the particles:
Pretreatment of raw materials: For raw materials with high fiber and many impurities, it is necessary to first remove large impurities and long fibers through crushing and screening to make the material texture more uniform, provide high-quality basic materials for granulation, and reduce granulation failure caused by uneven raw materials.
Adjust the disc parameters: According to the characteristics of the material, reasonably adjust the disc inclination angle and speed. If the angle is too small, the material is easy to accumulate; if the angle is too large, the material residence time is short. Too fast speed will cause the material to be thrown out due to excessive centrifugal force, and too slow speed will make it difficult to fully roll and agglomerate. By repeatedly debugging and finding the appropriate parameters, the material can form a stable rolling track in the disc and promote uniform growth of particles.
Adding binder: By increasing the spraying amount and uniformity of the binder, the bonding of the material can be improved, thereby improving the strength and uniformity of the particles.
Install screening device: Install drum screener machine in the fertilizer production line to separate unqualified particles and impurities in time, return them to the granulator for reprocessing, form a closed loop, reduce the waste of raw materials, and ensure the uniformity of the output particles.
Clean the equipment regularly: Clean the disc and the inside of the disc granulator regularly to prevent the accumulation of impurities from affecting the granulation effect.
Through these methods, the disc granulator can stably maintain a high granulation rate, improve the quality and efficiency of organic fertilizer production, and help produce high-quality granular fertilizer.
