In 2023, the main wire rope core conveyor belt of a large open-pit iron mine suddenly broke during operation, causing the entire line to stop production for 36 hours, with direct economic losses exceeding 5 million yuan. The main cause of the accident was the aging of the wire rope core conveyor belt equipment, multiple rusts on the wire rope core, and delamination at the vulcanized joint. The maintenance record showed that it was partially repaired 3 years ago and the joint failed. In order to prevent such incidents from happening, how should we prevent the conveyor belt from breaking? And what should we do first when the conveyor belt breaks?

First of all, when we use the wire rope core conveyor belt daily, we should strengthen the inspection and maintenance of the conveyor, improve the production environment, and make the wire cord rubber conveyor belt have a good working environment; we should regularly check and adjust the tensioning device to make the wire cord rubber conveyor belt have appropriate tension; the wire cord rubber conveyor belt should be loaded evenly to prevent concentrated overloading; keep the conveyor belt running without deviation, and the rollers and drums rotate flexibly; replace the conveyor belt with excessive wear in time and use qualified conveyor belts.

If a conveyor belt breaks, first ensure that the conveyor is stopped to avoid causing further damage. Before handling, a site safety inspection must be carried out to ensure that all operations are carried out under safe conditions. Then check the extent of the damage to the conveyor belt. If the damage to the conveyor belt is local and small, a hot bonding repair technique can be used. This method is suitable for any rubber conveyor belt, and the machine can be started and operated immediately after the repair. The repair technique includes roughening and cleaning the damaged surface, hot repairing with a special repair material, and then using it after the repair agent is cured. For longer or larger areas of damage, a mechanical joint method can be considered. This method is suitable for small belt conveyor equipment and has the characteristics of being economical, easy to operate, and fast to replace. After the repair is completed, restart the conveyor and conduct a short test run to ensure that the function of the conveyor belt has been restored. Check the status of the conveyor belt during use. If the problem recurs, it may be necessary to consider replacing the conveyor belt or further maintenance measures.
