To reduce the maintenance cost of organic fertilizer belt conveyor, we can start from the following aspects:

1. Preventive maintenance: Preventive maintenance is an important means to reduce maintenance costs. By regularly checking, lubricating and replacing wearing parts, sudden failures and maintenance costs can be effectively reduced.

2. Daily inspection and cleaning: Check whether the belt is damaged, cracked or aged before starting each time to ensure that the belt has no deviation or slipping problems. Clean the residual materials on the belt regularly to avoid uneven force on the belt caused by material accumulation and accelerated wear.

3. Lubrication and component maintenance: Regularly lubricate the transmission parts of organic fertilizer equipment to extend the service life. Regularly check the wear of vulnerable parts such as belts, rollers, and rollers, and replace severely worn parts in time.

4. Optimize equipment design: When selecting materials, consider strength, wear resistance and corrosion resistance to reduce wear and corrosion.

5. Troubleshooting and repair: When equipment fails, quickly troubleshoot and repair it.

6. Reasonable layout and planning: Reasonably plan the layout and path of the belt conveyor to reduce resistance and wear during the conveying process. By optimizing the production process, reduce the equipment's no-load operation time and reduce energy consumption.

7. Train operators: Train operators to ensure that they are familiar with the equipment's operating procedures and maintenance requirements to avoid equipment damage due to improper operation.

By implementing the above strategies, the maintenance cost of the organic fertilizer belt conveyor can be effectively reduced, the equipment life can be extended, and production efficiency can be improved.
