The stable operation of organic fertilizer production equipment is key to ensuring fertilizer quality and production efficiency. A scientific maintenance system can effectively extend equipment life and reduce the risk of failure. Targeted maintenance measures are required for equipment throughout the entire process, from pretreatment to finished product packaging, tailored to its characteristics.
Maintenance of pretreatment equipment focuses on preventing blockage and wear. As the first step in processing raw materials such as straw and manure, the crusher requires daily inspection for blade wear and weekly sharpening to prevent blunting and reduced pulverization efficiency. Screening machines require regular cleaning of residual fiber debris and monthly inspection of screen tension to prevent vibration-induced loosening that reduces screening accuracy. For conveying equipment, special attention should be paid to the tightness of the conveyor belt and the lubrication of the rollers to prevent failures caused by frictional overheating.
Granulating equipment requires timely cleaning and maintenance. The disc granulator‘s disc should be cleaned of residual particles daily and coated weekly with an anti-stick coating to prevent material from clumping and sticking. Bearings should be lubricated with high-temperature resistant grease monthly to ensure smooth rotation. The roller surface of the roller granulator should be regularly inspected for wear and any dents should be repaired promptly to avoid compromising pellet quality.
Maintenance of post-processing equipment focuses on precision and safety. The hot air ducts of the drum fertilizer dryer should be cleaned of dust monthly to prevent blockages that affect thermal efficiency. The temperature sensor should be calibrated weekly to ensure precise control of the drying temperature. The fan filter of the cooler should be cleaned regularly to prevent debris from entering and affecting heat dissipation. The metering device of the packaging machine should be calibrated weekly, and the drive chain of the conveyor belt should be lubricated monthly to ensure accurate quantitative packaging.
Establishing an equipment maintenance mechanism provides long-term protection. Recording the time, content, and troubleshooting of each maintenance session can help identify recurring problems promptly. Operators should also receive professional training to ensure early resolution of minor faults and early prevention of major problems. Scientific maintenance not only reduces equipment failure rates but also ensures the continuity and stability of the organic fertilizer production line, providing reliable support for the green development of agriculture.
