However, in actual use, the life of the belt conveyor is mostly determined by the life of the conveyor belt, since the conveyor belt is a standard elastomer device and is the most important component of the conveyor. The cost of the conveyer belt accounts for 30-50% of the cost of the belt conveyer. The belt conveyor can cause the fatigue phenomenon of the conveying belt to a great extent due to the long-distance uninterrupted transportation of a large amount of coal blocks and sundries thereof, and once the fatigue phenomenon cannot be fundamentally solved, the wear and even tear and fracture conditions of the conveying belt can occur. In addition, the quick repair is not carried out on the site, and the replaced conveying belt is often left unused or sold cheaply, so that the consumption of the conveying belt is increased. Therefore, in the design of the belt conveyor, corresponding measures are taken to reduce the abrasion of the conveying belt and prolong the service life of the conveying belt, thereby having practical significance for the normal operation and maintenance cost reduction of the belt conveyor.
The abrasion problem of the conveying belt not only accelerates the damage of the conveying belt, but also causes the leakage and the waste of materials. After the conveyer belt equipment problem appears usually, the enterprise is through frequent mending, heating vulcanization or scrap the renewal, and these modes can not fine solution actual problem, and the input of a large amount of manpower and material resources is needed in the heat vulcanization, and the time that the construction consumed is also very long simultaneously, scrap the renewal and have caused the rise of equipment purchasing cost especially.
