Immediate Actions

When a belt conveyor suddenly stops in a hightemperature environment, it is crucial to follow these steps for troubleshooting and handling:

1. Cut Off Power Immediately:

    Prevent further damage or danger by immediately cutting off the power supply.

2. Comprehensive Inspection:

    Conduct a thorough inspection to identify the cause of the stop. Possible reasons include motor stall protection mechanism activation, belt slipping, excessive belt slack, lateral movement or wear of the belt, and belt blockage caused by material return.

Common Causes and Solutions

Motor Stall Protection Mechanism

 Cause: Activation due to overload.

 Solution:

  1. Check the load condition of the conveyor.

  2. Ensure it is lower than the motor's rated load capacity.

  3. Adjust the load if necessary or inspect the motor for damage.

Belt Slipping

 Cause: Insufficient friction between the belt and the drum.

 Solution:

  1. Check and adjust the tension of the belt.

  2. Clean the drum to increase friction.

Excessive Belt Looseness or Lateral Movement

 Cause: Incorrect tension or alignment.

 Solution:

  1. Check and adjust the belt’s tension and position.

  2. Ensure stable operation by maintaining proper belt alignment.

Belt Blockage

 Cause: Material return causing blockage.

 Solution:

  1. Clean materials adhering to the belt.

  2. Inspect for design or operational issues in the material conveying system.

Safety Precautions

When troubleshooting and handling faults, always prioritize safety to avoid accidents such as burns and electric shocks. If the issue cannot be resolved independently, contact professional maintenance personnel promptly.

Preventive Measures

To prevent similar faults from occurring, regular maintenance and inspection of the belt conveyor are essential:

1. Regular Cleaning:

    Clean equipment regularly to prevent material buildup.

2. Check for Wear:

    Inspect belts and drums for wear and tear.

3. Adjust Tension and Position:

    Regularly adjust the tension and alignment of the belt.

4. Optimize Working Environment:

    Ensure proper ventilation and temperature control to provide a favorable working environment.

By following these steps, you can ensure the stable operation of belt conveyors even in hightemperature environments, minimizing downtime and maintaining productivity.

Conclusion

Troubleshooting a sudden belt conveyor stop in hightemperature environments requires a systematic approach. By cutting off power, conducting a thorough inspection, and addressing common causes, you can effectively handle and resolve the issue. Regular maintenance and attention to the working environment are key to preventing future occurrences.
