Causes of Belt Conveyor Deviation

There are many reasons for belt deviation, including internal factors within the belt conveyor itself and external environmental factors. However, they are generally attributed to factors such as unbalanced driving force on both sides of the belt and lateral forces exerted on the belt by rollers and idlers. From a force analysis perspective, these can be categorized into three types: first, unbalanced belt tension; second, stress (i.e., lateral force) generated by rollers and idlers that deviates from the belt's centerline; and third, unbalanced friction between the rollers and idlers and the belt.
