Maintenance Tips for Belt Weigher and Feeder: Equipment Maintenance and Common Troubleshooting

Belt weigher and feeder is production equipment commonly found in cement, chemical, building materials, environmental protection, and other fields. It is used for automatic conveyance, dynamic measurement, and quantitative control of various powdered, block, and other materials, providing great support for the control and management of production activities.

Belt weigher and feeder is applied in various industrial environments and plays a significant role in production. Therefore, it is essential to ensure its stability and continuous operation.

The stability and accuracy of belt weigher and feeder during practical application are not only related to its design, manufacturing, and technology application but also depend on application maintenance and troubleshooting.

Common Maintenance Items for Belt Weigher and Feeder

1. Belt

   - Check if the conveyor belt is centered on the roller: Adjust the left and right threaded rods of the tensioning device with a deviation of no more than ±10mm.

   - Belt tension under no load: Adjust the tensioning threaded rod.

   - Check for damage on the surface and edges of the conveyor belt: Repair or replace the belt if damaged.

   - Check for material adherence on the belt: Clean adhered materials promptly.

2. Feeder

   - Check for material accumulation inside the feeder: Clean promptly if found.

3. Driving and Driven Rollers

   - Check if the driving and driven rollers are stable, if the axles are excessively worn or bent, and if the rubber layer is scratched or peeled: Replace bearings or rollers if necessary.

4. Idlers

   - Check if the idlers run smoothly and if the surface is worn: Replace bearings or idlers.

5. Conveyor Belt

   - Check for excessive wear, surface scratches, cracks, faults, or edge tears on the belt: Repair or replace the belt if necessary.

6. Bearings

   - Check if the bearings rotate smoothly and if they are excessively worn: Regularly lubricate and clean; replace bearings if worn out.

7. Coupling Elastomer

   - Check for aging and cracks: Replace the elastomer if found.

8. Sealing Elements

   - Check for aging and wear: Clean promptly and replace if necessary.

9. Weighing Idler

   - Check if the weighing idler rotates smoothly and flexibly and inspect surface wear: Regularly lubricate and replace the weighing idler if necessary.

10. Sensors

- Check if the sensors and roller axles are correctly installed and if the corrugated tubes are damaged: Correct installation errors and replace corrugated tubes.

11. Connecting Bolts

- Check if the bolts are loose: Tighten bolts promptly.

Common Faults of Belt Weigher and Feeder

1. Deviation between Measured Value and Actual Value

   - Measured value is larger than the actual value: Possible causes include heavy objects on the weighing idler, deformation of the scale body, or deformation or damage to the weighing sensor.

   - Measured value is smaller than the actual value: Possible causes include materials or stones stuck on the weighing idler, lifting the weighing idler; clean the stones and dust near the weighing idler promptly; possible sensor damage.

2. Deviation between Speed Value and Actual Value

   - Possible causes include the speed sensor being too far from the measured flange, failing to capture the true pulse signal, resulting in a speed value lower than the actual value; possible speed sensor damage.

3. Discrepancy between Measured Value and Set Value

   - The measured value sometimes cannot track the set value of the feeder. First, check if all parameters are set correctly, then consider signal issues; if the signal is normal, consider inappropriate control parameters and adjust the relevant coefficients.

4. Unexpected Stop of the Feeder

   - If the belt is too loose, it may cause slipping between the belt and the roller, resulting in the motor running but the belt not turning. Regular inspections are required to ensure belt tension, and an automatic tensioning device can be installed.
