Abstract
There is provided a conveyor belt for marginal life prediction, in which wear of the degree of the conveyor belt can be well and visually recognized without stopping of the conveyor belt on operation, and the replacement time of the conveyor belt can be easily predicted in advance, thereby to predict and efficiently manage the life time of the conveyor belt. It was difficult to check abrasion extents step by step and exactly predict the life time in the conventional conveyor belts. Further, the accidents of carrying articles released out of the conveyor belt were frequently occurred since troughs of the conveyor belt are not formed enough, and the angle of the trough is so small. As the way of solving the problems as above, while the wear of the conveyor belt is progressed, and when the abrasion check colored rubbers, which are embedded inside the conveyor belt, are exposed outwardly and checked visually by eyes, the extent of the abrasion of the conveyor belt can be estimated and the exchange time of the conveyor belt can be well predicted. The number of the exposed abrasion check colored rubbers is well detected by installing the abrasion check colored rubbers in multi-layers wit…
