Reducing the maintenance cost of organic fertilizer production lines requires prioritizing "prevention and precise control." Optimizing the entire equipment management process can reduce breakdown losses and unnecessary expenses.

First, establishing a preventive maintenance system is crucial. Abandoning the "failure repair" model, develop a periodic maintenance plan based on equipment type. For fermentation compost turner, weekly clean residual material from the shovel and check chain tension to prevent material buildup and wear on parts.

Second, optimizing the management of core components can reduce replacement costs. Preferring wear- and corrosion-resistant adapters is recommended. Furthermore, categorizing worn parts, such as repairing turner shovels with minor wear and replacing only severely damaged parts, reduces the frequency of new part procurement.

Standardizing operating procedures can reduce human losses. Regular operator training should be conducted to clarify equipment start-up and shutdown sequences (for example, preheating organic fertilizer granulators before feeding) and load limits (to avoid exceeding rated capacity). Establishing operational assessment standards will control violations that lead to equipment failures. This will reduce problems such as gear wear and motor overload caused by improper operation and reduce maintenance frequency. Finally, appropriate technological upgrades can reduce costs in the long term. Retrofitting older equipment with intelligent control systems, such as equipping feeders with variable frequency drive speed controllers, can prevent uneven feeding and equipment overload. Replacing traditional manual cleaning with automated cleaning systems can reduce maintenance costs. While this may require initial investment, it can significantly reduce long-term failure rates and maintenance costs.
