Conveyor belts, no matter how durable, are susceptible to damage – especially if they are continually used for various operations. Breakages must be repaired to avoid further damage that could lead to operational delays.
Here are some troubleshooting guidelines to some of the more common conveyor belt problems.
Excessive belt stretch
|
Causes |
Solutions |
| Start-up tension is too great for the belt | Decrease the load
Increase the speed Decrease the incline angle Increase tension rating and plies in the belt |
| Belt is not fit for the generated tension | Switch to a higher tension belt |
Cracking or hardening of belt covers
|
Causes |
Solutions |
| Chemical or heat damage to the belt | Be sure to choose the correct belt carcass and compounds for your application |
| Ozone and Ultraviolet light cause compound degradation during long term storage | Store out of direct sunlight
Utilise spare belts as soon as possible |
Incorrect tracking when the belt is loaded
|
Causes |
Solutions |
| Off centre or improper loading of the belt | Make sure that the material going down the chute is facing the direction in which the belt is travelling |
| Variations in the nature and formation of the load at the load point | Use a deflector/notched chute to make the load peak as close to the belt’s centre as possible |
