The core of organic fertilizer equipment maintenance is prevention-oriented and regular upkeep. By performing targeted maintenance on each component of the equipment, the service life can be extended, fault downtime reduced, and production stability ensured.

Key Points for Core Equipment Maintenance

Due to differences in functionality and structure, the maintenance priorities vary among different equipment types, requiring precise control at each stage.

1. Pre-processing equipment (grinder, sieve, mixer)

Grinder: Regularly inspect the wear of blades or hammer pieces and replace them promptly if severe wear is detected to avoid reduced grinding efficiency. After each use, clean the residual material inside the machine to prevent clogging from material clumping.

Screening machine: Regularly inspect the damage and clogging of the screen mesh. Promptly repair or replace any damaged parts. Periodically clean impurities from the screen surface to ensure screening efficiency.

Mixing Machine: Inspect the fastening condition of the mixing blades to prevent loosening or breakage; regularly lubricate moving parts (such as bearings) to reduce friction wear.

2. Fermentation Equipment (Fermentation Tumbler, Fermentation Tank)

Fermentation Turner: Before operation, inspect the integrity of the turning teeth. Replace any bent or broken teeth immediately. Remove any adhered fermentation material from the equipment to prevent corrosion of components. Regularly check the hydraulic system to ensure normal oil pressure and no leaks.

Fermentation Tank: Regularly remove residual materials and scale buildup inside the tank to prevent microbial growth that may affect fermentation efficiency; inspect the sealing integrity of gaskets to avoid gas leakage leading to temperature fluctuations; maintain temperature and humidity sensors to ensure accurate monitoring data.

3. Deep processing equipment (granulator, dryer, cooler)

Pelletizing machine: Inspect the wear of the pelletizing mold or rollers, and promptly repair or replace them if the wear exceeds the standard; clear the blocked material inside the mold holes to ensure uniform pellet formation; regularly lubricate the transmission parts to prevent jamming.

Dryer / Cooler: Remove adhered materials from the inner wall of the drum to prevent affecting heat exchange efficiency; inspect the operation status of the hot air furnace or cooling fan to ensure stable temperature and airflow; maintain the conveyor belt to prevent misalignment or slippage.

4. Post-processing Equipment (Screening Machine, Coating Machine, Packaging Machine)

```Coating machine: After each use, clean the residual coating agent from the coating roller to prevent caking; inspect the spray system nozzles to ensure uniform atomization and avoid blockages.```.

Packaging Machine: Regularly calibrate the weighing sensor to ensure accurate packaging weight; clean residual material from the discharge port to prevent blockages; inspect the conveyor belt and sealing device to ensure packaging integrity and smooth operation.
