The daily maintenance cycle for organic fertilizer production line equipment should be comprehensively determined based on the equipment type (e.g., crushing, granulating, drying), characteristics of core components (wearable parts / transmission parts / electrical parts), and usage frequency. Adhering to the principle of "frequent inspections to prevent sudden failures and regular maintenance to extend lifespan," it can be divided into five levels: daily maintenance, weekly maintenance, monthly maintenance, quarterly maintenance, and annual maintenance.

1. Flexible Adjustment Principle: If the production line operates for more than 8 hours daily (full-load production) or the raw materials have high impurity levels and strong corrosiveness (such as high-salt food waste), the maintenance cycle should be shortened (e.g., weekly maintenance to every 5 days, quarterly maintenance to every 2 months).

2. Reference for Wearable Parts Lifespan: The lifespan of different wearable parts varies and can serve as supplementary criteria for maintenance cycles (e.g., screens 3-6 months, bearings 6-12 months, filter cloths 1-3 months). Stock spare parts in advance to avoid production downtime during replacements.

3. Record Tracing: Establish an "Equipment Maintenance Ledger" to document the time, content, and replaced parts model for each maintenance instance, facilitating the tracing of fault causes (e.g., if a motor frequently overheats, the ledger can be checked to determine if long-term lubrication deficiency is the issue).

4. Through the above hierarchical maintenance cycle, "daily prevention of minor faults and periodic elimination of major hazards" can be achieved, extending equipment lifespan and ensuring stable production line operation throughout the year.
