As the core equipment in fertilizer production, the service life of NPK fertilizer production lines directly impacts a company's production efficiency and economic benefits. Extending the service life of the production line requires comprehensive control throughout the entire process, focusing on equipment maintenance, production standards, and environmental adaptation to achieve long-term stable operation.

Strengthening daily maintenance is the fundamental prerequisite for extending the service life of the production line. Companies need to establish a scientific and standardized routine inspection and maintenance mechanism, arranging professional maintenance personnel to meticulously check the operating status of key equipment such as crushers, mixers, granulators, and conveyors daily.  They should focus on identifying abnormal noises, leaks, and vibrations, and promptly clean residual fertilizer clumps and material residues from inside the equipment and pipelines to prevent long-term accumulation from causing component corrosion, pipeline blockage, or equipment jamming. For core transmission parts such as bearings, gears, and chains, lubricating oil of the appropriate type should be added regularly according to the equipment manual to effectively reduce mechanical wear and operating resistance; for easily worn parts such as screens, scrapers, and seals, a dedicated spare parts inventory should be established, with clear replacement cycles.  Any signs of damage or aging should be addressed immediately to prevent minor malfunctions from escalating into major equipment overhauls and to ensure continuous operation of the production line.
Standardized production operations are crucial. Strictly follow production process parameters and avoid overloading—excessive feeding increases the load on the equipment motor, and prolonged overloading can easily lead to motor burnout and machine body deformation. In the raw material pretreatment stage, strictly control the moisture content and impurity content of the materials to prevent hard impurities from entering the equipment and causing component scratches, and to avoid high humidity leading to material sticking and scaling, thereby reducing the risk of equipment corrosion.
Ensure proper environmental protection and regular inspections. The dust and corrosive gases generated during the NPK fertilizer production process can easily corrode the equipment.  Therefore, complete dust removal and anti-corrosion facilities are necessary to keep the production workshop dry and well-ventilated. Conduct comprehensive inspections 1-2 times a year, performing non-destructive testing and precision calibration on the equipment, and promptly repairing minor cracks and deformations.  Based on technological development trends, upgrade and modify older components as needed to improve equipment performance and stability.
In summary, extending the service life of the NPK production line requires an integrated approach that combines daily maintenance, standardized operation, and regular inspections, forming a comprehensive life-cycle management system. This approach will not only reduce equipment failure rates but also improve production efficiency, thus laying a solid foundation for the sustainable development of the enterprise.
