Common causes of conveyor belt failure and its treatment method

Advantage belt conveyor widely used in mining, metallurgy, coal and other departments, the conveyor belt has a transport capacity, simple structure, convenient maintenance, standardized components. However, belt conveyors often have some faults during the working process. The common causes and treatment methods of belt conveyors are introduced below to facilitate more systematic management and maintenance in daily production and maintenance.
Belt conveyor belt deviation processing:
Belt deviation is the most common failure when the belt conveyor is running. In order to solve such failures, it is important to pay attention to the dimensional accuracy of the installation and daily maintenance. There are many reasons for deviation, and it needs to be treated differently according to different reasons.
1. Installation of the self-aligning roller set: There are various types of self-aligning roller sets, such as intermediate rotary shaft type, four-link type, vertical roller type, etc. The principle is to block or produce a lateral direction by blocking or idler in the horizontal plane. The thrust makes the belt automatically center-to-center to adjust the belt deviation.
This method is generally reasonable when the total length of the belt conveyor is short or when the belt conveyor is operated in both directions, because the shorter belt conveyor is more prone to deviation and is not easy to adjust. Long belt conveyors are best not to use this method, because the use of the centering roller set will have a certain impact on the life of the belt.
2, the adjustment of the tension: the adjustment of the belt tension is a very important part of the belt conveyor deviation adjustment. The two redirecting rollers on the upper part of the heavy hammer tensioning should be perpendicular to the vertical line of gravity in addition to the longitudinal direction of the belt, that is, the horizontal centerline of the shaft is ensured.
When using a screw tension or hydraulic cylinder tensioning, the two housings of the tensioning drum should be translated simultaneously to ensure that the drum axis is perpendicular to the longitudinal direction of the belt. The specific method of adjusting the belt deviation is similar to the adjustment at the drum.
