MULTI-PLY CONVEYOR BELT are affected by factors such as industrial and mining conditions, operating time, and unexpected situations, resulting in frequent wear, aging, degumming, scratches, and tears. As far as the wear and scratches of the conveyor belt are concerned, combined with many field cases, the wear problem mainly occurs on the non-bearing surface, and the scratches are mainly caused by unexpected conditions on the bearing surface. During the operation of the MULTI-PLY CONVEYOR BELT, there is not only theoretical rolling friction, but also sliding friction between the non-bearing surface and the idler.

At the same time, affected by equipment maintenance and external environment, the roller bearing is poorly lubricated or dust intrusion causes uneven rotation or even stops rotating, and the sliding friction is more obvious at this time. The friction and wear of the bearing surface is mainly caused by the material, mainly during the loading and unloading time, and the bearing surface of the conveyor belt and the material are relatively static for most of the rest of the time.

Therefore, it will be found that when the bearing surface is still relatively intact, the non-bearing surface has been severely worn and even exposed the steel wire. In addition, affected by the production capacity, the speed of the conveyor continues to increase, and the frictional heat between the MULTI-PLY CONVEYOR BELT and the rollers and rollers will also increase accordingly, which also accelerates the wear of the non-bearing surface of the conveyor belt.
