Sungda Conveyor Belt Co.,Ltd.

The ep conveyor belt runs through the entire length of the conveyor. In addition to the conventional damage during the operation of the ep conveyor belt, the conveyor belt will be broken due to various accidental factors, which not only brings huge economic losses but also causes safety accidents in severe cases. Therefore, it is necessary to analyze the cause of the belt breakage and take targeted control measures.

A. EP conveyor belt edge tearing

Conveyor belt edge tearing is the most common form of conveyor belt tearing, the root cause of which is the excessive deviation of the ep conveyor belt. There are many reasons for the deviation of the conveyor belt, but it can be divided into two types:

The first is the device installation problem or the poor quality itself. Common factors are:

1 frame, roller bracket sinking or deformation;

2 The loading roller set is not installed correctly;

3 tensioning device is skewed;

4 EP conveyor belt splicing section are not equal.

Secondly, due to poor operating conditions. Reasons include:

1 blanking point deflection;

2 Unloader pressure is uneven;

3 too much material stuck on the surface of the drum;

4 The amount of carried material changes or the occurrence of flow conditions and other factors cause the ep conveyor belt to run off.

B. Inside longitudinal tear

Longitudinal tearing of the conveyor belt refers to the occurrence of large cracks or complete tears, which is the most serious form of conveyor belt damage. The main causes of longitudinal tearing on the inside of the conveyor belt are:

1 There are hard objects such as iron pieces and large stones in the material. During the transportation process, these impurities are stuck in the guide trough or hung in the middle of the structure such as the cleaner roller, causing the conveyor belt to be scratched or torn in the longitudinal direction.

2 The solid parts of the upper equipment are loose and fall off, or the vibration impact causes the material guide plate of the material pipe to fall, etc., which is stuck in the guide groove or other parts to cause the scratched conveyor belt.

3 The conveyor idler is continuously missing, the conveyor belt sinks under load, and the roller bracket wears the conveyor belt.

4 The ep conveyor belt joint is opened or partially damaged. No measures are taken. During operation, it is hung by the plow, the cleaner, and the buffer bed.

5 During the operation, there are sharp foreign objects such as sweepers, rollers, vermiculite, and iron pieces, which are brought into the drum and the return ep conveyor belt to cause scratches until tearing.
