What are the common faults of drum screening machine in organic fertilizer production

 In the process of organic fertilizer production, the drum screening machine, as a key equipment, may encounter various problems that affect its normal operation. Understanding these common faults and their solutions helps to respond quickly and ensure efficient operation of the production line. The following are some typical faults and coping strategies of drum screening machines:

Fault 1: Screen blockag:

Reason: The material contains too much water, increases viscosity, or the sieve size design is unreasonable.

terms of settlement:

Adjust the moisture content of the material to ensure it is in its optimal state; Clean the residue on the sieve and regularly check whether the sieve holes need to be enlarged or replaced with new ones.

Fault 2: The drum is not running smoothly

Reason: The bearing is short of oil, severely worn, or the drum is unbalanced.

terms of settlement:

Regularly lubricate the bearings, add or replace grease; Check the balance of the drum and recalibrate or replace the drum components if necessary.

Fault 3: Abnormal noise

Reason: Loose bolts, collision of internal parts of the drum, or damage to the drum shell.

terms of settlement:

Tighten all connecting bolts to ensure there is no looseness; Check for foreign objects inside the drum and remove any items that may cause collision; Repair or replace damaged drum components.

Fault 4: Decreased screening efficiency

Reason: Excessive wear of the screen or excessive material flow, exceeding the equipment's processing capacity.

terms of settlement:

Replace the severely worn screen mesh to ensure screening accuracy; Control the feeding amount of materials to avoid overload operation, and upgrade the equipment model if necessary.

Fault 5: Electrical control system malfunction

Reason: Aging wires, poor contact, or controller malfunction.

terms of settlement:

Check the circuit connections and replace aged or damaged wires; Regularly maintain the electrical control box, clean dust, and ensure that electrical components work properly.

Regular maintenance checks and appropriate troubleshooting are key to maintaining the efficient operation of the drum screening machine. Establishing a comprehensive maintenance plan and training operators on the proper use and daily inspection of equipment can significantly reduce the occurrence of sudden failures, extend equipment lifespan, and ensure the smooth operation of organic fertilizer production lines.
