Problem |
Reason |
Solution |
| 1 |
Conveyor belt runs on one side of the conveyor. |
Idlers or pulleys are out-of-square with the center of the belt |
Re-adjus the idlers or pulleys in the affected areas |
| Sticking idlers |
Improve maintenance o rlubrication |
| Structurenot level |
Readjust the structure in affected area to make it level |
| 2 |
Belt Slippage. |
Traction force between belt and pulleys isn't enough |
Increase pulleys pads area or install belt cleaning device |
| Lagging on pulleys is worn or damaged |
Change the pulleys |
| Bob-weight is too light |
Increase the Counterweight level in accordance with the conveyor calculations |
| 3 |
Conveyor Belting is stretching excessively. |
Tension is high |
Increase the belt speed or reduce the traffic amount;reduce the friction and replace the damaged idlers |
| Belt stretch excessively by wrong installation of the belt |
Adopt the mechanized clamping device for the belt |
| Distance of bob-weight is not enough |
Refer to the belt selection manual to obtain the correct minimum length of the Counterweight |
| 4 |
Top cover of the belt wear down excessively. |
Quality of the cover rubber is too bad |
Change the high quality cover belt |
| Load bias the center line of the belt |
Readjust the blowpit to make the load on the center of the belt |
| Overrelaxation between the idlers |
Increase the tension or reduce the span |
| 5 |
Bottom rubber of the belt wear down excessively. |
Slipping at the pulleys |
Fastening pulleys or increase the contact area of the pad |
| Materials deposit between the belt and idlers |
Install the cleaning device at the return side of the idlers tail |
| Traffic Idlers incline forward excessively |
Reduce the angle of inclination |
| 6 |
Covers harden or crack. |
Damage of the heat or chemistry |
Choose the belts with special parameters |
| Wrong storage or handling |
Refer to the belt instructions |
| 7 |
Cover swells in spots of the belt |
Idlers are lubricated excessively to make the oil overflow |
Improve the maintenance to reduce the oil number. |
| 8 |
Vulcanized splice separation |
Tension is too high |
Improve the belt speed or reduce the traffic amount;reduce the friction and replace the damaged idlers |
| Idlers are too small |
Use the morebigger diameter idlers |
| Wrong installation of the belt splice |
Adopt the correct method of splicing |
