| Trouble | Reason | Troubleshooting |
| The same part of the conveyor belt running out | Poorly joint | reconnect |
| | Belt edges worn and deformed by moisture | Repair of damaged areas |
| | Bending of conveyor belt bodies | Straightening with centering rollers |
| Belt runout near the same rollers | Localised deformation of the conveyor | Correct the deformed position in time |
| | The rollers are not adjusted properly | correct the rollers |
| | Unclean rollers | Removal of adhesions |
| | Dislodged rollers | Install the rollers and maintain them in good time |
| Belt runout at no load | Poor trough-ablitily | Increase in initial belt tension |
| | Poor flexibility | The belt needs to be replaced if the alignment rollers are still not effective |
| | Too small initial tension on the belt | increase initial tension |
| Belt runout under load | Improper placement of materials | Adjust the position of the discharge chute so that the material falls in the centre of the conveyor belt |
| | Material diameter too large in relation to belt width | Crushing the material, or changing the bandwidth |
| Belt runout at the head or tail of the machine | Inaccurate pulley centres | Adjust the centre of pulley |
| | unclean pulley | Removal of adhesions， check the cleaner |
| Early wear and tear of the belt top rubber | The baffle plate is unsuitable | Adjust the baffle plate |
| | Impacted by large pieces of material | Improve the feeding condition，reduce the impact |
| | Feeding too fast, or too high | Improve the feeding condition，reduce the impact |
| Early wear and tear of the belt bottom rubber | Belt slip on the drive roller | Increasing the coefficient of friction of the drive roller |
| | Inflexible upper roller | Improve the drive condition of rollers |
| | unclean rollers | Removal of adhesions |
| Early wear and tear of the belt edge | belt run to one side | Deflection correction for conveyor belts |
| | Poor trough-ability | Adjust drive roller |
| Early wear and tear of the belt carcass | Impacted by large pieces of sharp-edged material | Crushing the material |
| | Large pieces of material and foreign objects get caught between the belt and the pulley | Prevents foreign bodies from falling between the belt and pulley |
| | Hooked by a hard object at the discharge chute | Install metal detectors |
| Longitudinal tearing of conveyor belts | Foreign object falls and gets stuck after poking through the belt | Always check rack accessories |
| | Rollers fall off after wear | Installation of v-shaped scrapers at the tail roller |
| | Large foreign object falling | Installation of suspended belt magnet separator |
