A conveyor belt is a critical asset for the mining production process and can travel long distances, which is why the vibration sensor is so relevant for monitoring the asset. The coupling, in turn, is responsible for the connection between the motor and the gearbox, and may present, in some cases, wear and misalignment.
Failure analysis is a critical process aimed at determining the root cause of every failure. Failure of conveyor chain links in the industry has many repercussions which include; uncsheduled down - time which reduces production time coupled with damaged buckets and chain links which increases maintenance and repair cost.

Systematic Approach to Diagnosing Conveyor Belt Failure. Diagnosing the causes of conveyor belt failure involves a methodical process that includes inspection, data collection, and failure analysis of belt conveyor systems. Here is a step-by-step approach to systematically identify the root causes of conveyor belt failures:
The shaft of a conveyor belt drive pulley failed in service. An investigation was performed in order to determine the failure root cause and contribution factors. Investigation methods included visual examination, optical and scanning electron microscope analysis, chemical analysis of the material and mechanical tests.
