An organic fertilizer disc granulator is a core piece of equipment in organic fertilizer production. With its advantages of uniform pellet formation, simple operation, and high cost-effectiveness, it is widely used in the granulation processing of organic materials such as livestock and poultry manure, straw, and humic acid. Properly mastering the equipment’s operating methods is crucial for ensuring the quality of the finished granules, improving production efficiency, and extending the equipment’s lifespan, making it key to large-scale organic fertilizer production.
A thorough pre-start inspection is fundamental to stable equipment operation. Operators must clean any residual material and debris from inside the disc, check the lubrication of the motor and reducer to ensure sufficient oil levels. Simultaneously, check the equipment’s fixing bolts and drive belts for integrity, confirm the disc’s rotation direction is correct, and ensure the machine body is not loose or shaking. Furthermore, raw materials need to be pre-processed; the matured organic fertilizer should be crushed and sieved, controlling the material’s moisture content to 30% to 35% to avoid impurities and large pieces affecting the granulation effect.
The equipment should be operated gradually. After starting the equipment, wait for the disc to run smoothly before immediately feeding at full load. First, feed one-third of the rated material to form a stable layer of 5 to 8 cm, then slowly increase the feed rate. Simultaneously turn on the spray device, fine-tuning the water volume according to the material’s moisture content. For low-viscosity straw materials, a suitable amount of binder can be added. The equipment relies on the centrifugal force and friction generated by the tilting and rotating disc to agglomerate the material layer by layer into granules. During the process, observe the granule state in real time; add water if loose, reduce water if clumped, ensuring uniform granule size.
Real-time control and safety precautions are essential during disc granulation. Adjust the disc tilt angle and speed promptly to adapt to the granulation requirements of different materials. Never touch the disc surface while the equipment is running. If jamming, abnormal noises, or other malfunctions occur, immediately stop the machine and disconnect the power for troubleshooting; never operate with a malfunction. After production, stop feeding and spraying first, and only turn off the power after all material has been granulated and discharged.
Daily maintenance is indispensable. Clean any adhering material from the disc surface after each operation to keep the equipment clean. Regularly check the wear of transmission components and bearings, and add lubricating oil as needed. Standardized operation and regular maintenance can keep the pelleting rate of the equipment stable at over 90%, effectively reducing raw material loss and helping the organic fertilizer production line to produce high-quality and efficient products.
