Deep learning-based damage detection of mining conveyor belt
The conveyor belt, as an important part of the belt conveyor, plays a role in carrying materials and transferring power, and its cost accounts for 30%–50% of the total cost of the conveyor [13]. Conveyor belts often suffer longitudinal tearing, surface scratches, and other damage when the rollers are broken or the material is jammed [14]. …

From the other hand the shorter and wider the belt, the better a push operated belt conveyor will work. This is again due to the friction that can be achieved between the drive roller and the belt. A wider roller has more surface area and allows for more friction. The weight placed onto the conveyor must be kept low in this mode of operation.
