The disc granulator is a key piece of equipment in fertilizer production. Its stable operation and high-quality granulation require precise control of operational details. Mastering these key precautions can effectively improve production efficiency, ensure granule quality, and lay a solid foundation for your organic fertilizer production line.

Raw material pretreatment requires meticulous care. The material entering the granulator must be of uniform particle size and free of large impurities, which can prevent equipment jams and affect granule formation. The moisture content must also be strictly controlled. Excessive moisture content can easily cause granules to clump, while excessive moisture content can hinder granulation. Maintaining the moisture content within an appropriate range is crucial for granulation.
Operating parameter adjustment is crucial for quality control. Before starting the machine, calibrate the disc inclination angle. Set an appropriate angle of 45°-55° based on the material's characteristics to ensure stable granule rolling within the disc. Monitor the speed in real time during operation. Too fast a speed can result in overly fine granules, while too slow a speed can result in overly large and uneven granules. This requires flexible adjustment using the frequency conversion system. Furthermore, binder should be added evenly. Excessive amounts can result in hard granules, while too little can cause them to loosen easily. Precise control is essential based on the material's viscosity. Equipment maintenance is essential. Clean the inner surface of the disc after daily downtime to prevent caking and hardening that could affect the next day's granulation. Pay particular attention to clearing any accumulated material from the edges and crevices. Regularly check the lubrication of transmission components and apply specialized lubricant to bearings, gears, and other components to prevent dry friction and increased wear. If the disc liner is worn or deformed, replace it promptly to ensure stable pellet formation.
Safety operating procedures must be strictly adhered to. Operators must wear protective equipment to avoid injury from material splashing. Never insert hands or tools into the disc while the machine is operating; adjustments require the machine to be shut down. Regularly inspect the electrical wiring to prevent short circuits and leakage to ensure safe production.
By observing these precautions, the disc granulator can consistently and stably produce uniform, solid fertilizer granules, reducing downtime and lowering costs. In the pursuit of efficient and high-quality fertilizer production, the scientific and standardized use of the disc granulator is key to enhancing product competitiveness.
