Cause analysis and improvement measures of belt deviation of sidewall belt

(1) Cause of failure

The sidewall belt often encounters the problem of belt deviation. The phenomena are generally as follows: the belt running to one side causes the axis of the idler group and the belt center line to be not vertical, which causes deviation; the roller is not level, which causes the belt deviation. The surface of the drum sticks to the material, making the drum a conical surface, which makes the belt deviate to one side; when the conveying material is hot and sticky and sticks to the drum, it is more likely to cause the belt to deviate; when both sides of the frame The difference in height makes the belt not level, and the material on the belt moves to the lower side during operation, which will also cause deviation; when the belt is unloaded, an empty car runs sideways, but it can be corrected by adding materials. This phenomenon may occur It is caused by excessive tension.

(2) Improvement measures

Usually, we often see the problem of belt deviation, and the adjustment methods adopted are different. It can be used to adjust the adjusting screw of the tail drum, adjust the pressure of the tail, adjust the roller device, the method of adding spacers to the roller or the method of cleaning the transmission roller and the tail roller to deal with the ore. Therefore, equipment maintenance personnel in production and front-line equipment must observe the cause of deviation on the spot and find the correct method to correspond to the deviation.
