To ensure the efficient operation and extend the service life of the drum fertilizer dryer, regular maintenance and upkeep are necessary. The following are some specific maintenance methods and suggestions:

1. Daily maintenance: After the end of each day's work, clean the residual materials inside the drum to prevent material accumulation and caking. Regularly clean the outer surface of the equipment, including the body, bracket and transmission device, etc., to remove dust, oil stains and other debris. Clean the hot air channels to ensure smooth air circulation and prevent the reduction of heat exchange efficiency due to dust accumulation.

2. Regular maintenance: Open the back box cover and clean the interior of the organic fertilizer equipment with a soft cotton cloth. Add lubricating oil to moving parts such as bearings to reduce friction. Check the degree of wear of easily worn parts and replace them in time. Check whether the fixing bolts of the machine base are loose and tighten them. Check the tightness of the support spring connection and make adjustments. Check the grounding condition of the equipment to ensure reliable grounding.

3. Troubleshooting: Increase fuel supply, reduce feeding speed, raise hot air temperature, and repair or optimize the raster. Reinforce the equipment installation, adjust the drum and material distribution, replace worn parts, and adjust the gear clearance.

4. Safe operation: Before starting the machine, check whether the bolts of all parts of the equipment are loose and inspect the wear of vulnerable parts such as the teeth claws and screens. Check the gas source three-piece set to ensure sufficient oil level and drain the remaining water. Assign dedicated personnel to monitor the operating parameters of the equipment, such as temperature, pressure, rotational speed, etc., and promptly identify and solve problems.

Through the above maintenance measures, the service life of the drum dryer can be effectively prolonged, production efficiency can be improved, and the stable operation of the equipment can be ensured.
