The three main forms of wear of conveyor belts in operation

The main reason for the replacement of the conveyor belt is wear, which is generally divided into the following three forms:

1. The wear at the vulcanized joint of the conveyor belt is usually caused by the higher abrasion resistance of the material of the conveyor belt than the rubber layer at the vulcanized joint or thermal vulcanization quality. The strength of the vulcanized joint between the two poses a serious threat.

2. Conveyor belt is worn on the skirt

Due to the improper adjustment of the skirt board of the conveyor belt guide device or the poor design of the guide skirt board, the skirt board will wear the conveyor belt during operation, causing serious wear of the rubber layer on both sides of the conveyor belt, and the steel rope is exposed in the longitudinal direction of the entire belt. The core or nylon core, once the polyester is lifted, it is easy to wrap around the idler, causing the wire strip to fall off or the tape to tear.

3. The abrasion of the middle part of the conveyor belt is caused by the impact of the falling material. Because the falling point of the hopper is relatively fixed, the part of the conveyor belt that is subjected to the impact is intensified, causing serious local wear along the running direction of the conveyor belt, and also resulting in exposed steel ropes. The core is stripped or the conveyor belt is torn. For nylon rubber conveyor belts, the strength of the middle part is reduced. Because the carrying roller has a forward inclination angle of 3 to 4°, under the action of the centering force of the carrying roller, the dangerous phenomenon of “double belt” will occur during the operation of the conveyor belt. .

The above three are the main wear phenomena of conveyor belts in operation.
