Overheating and overload in organic fertilizer disk granualtor machines are mostly caused by uneven feeding, excessively wet and clumping materials, poor lubrication, and excessive load. Proper operation and daily maintenance can effectively prevent these issues.

Before starting the machine, check the fertilizer making machine: Clean any clumping material from the discs to ensure no hard objects remain; check that the reducer and bearings are adequately lubricated, the belts and chains are properly tensioned, the protective covers are secure, and the motor wiring is normal. Perform a no-load test run for 2-3 minutes to confirm smooth operation and no abnormal noise before feeding material.

Strictly control the material and feeding: The moisture content of the raw material should be controlled between 25% and 35%. Excessive moisture will cause sticking to the discs, making pelleting difficult and increasing the load; excessive dryness will result in excessive dust and difficulty in pelleting. Use uniform and continuous feeding; avoid feeding large amounts of material at once to prevent material accumulation and overload in the discs. Add water evenly and appropriately to the spray system to prevent localized excessive moisture and clumping, which increases the motor load.

Key monitoring during operation: Closely observe the main motor current, keeping it within the rated range. If the current suddenly increases, immediately reduce the feed or stop the machine for cleaning. Pay attention to equipment temperature. Bearing and reducer temperatures should not exceed 60℃. If overheating, abnormal noise, or excessive vibration occurs, immediately stop the machine for inspection; do not force operation with defects. Promptly clean any material stuck to the trays and edges to reduce operating resistance and prevent continuous load increases.

Shutdown and Maintenance: Stop feeding first, and only stop the machine after the material in the trays has been mostly discharged. Avoid starting under heavy load with material. Check lubrication points every shift and add lubricating oil regularly. Regularly check the wear of belts, bearings, and reducers, and replace worn parts promptly. Keep the equipment clean and prevent dust from entering the bearings and motor.
