Install aligning idlers

There are many types of aligning idlers, such as intermediate shaft type, four-link type, vertical roller type, etc. The principle is to use the blocking or idlers in the horizontal plane, the direction of rotation to block or generate transverse thrust to automatically center the belt to achieve the purpose of adjusting the belt deviation.

It is reasonable to adopt this method when the belt conveyor is short in total length or in two-way operation, because the shorter belt conveyor is easier to run off course and not easy to adjust. The long belt conveyor does not use this method, because the use of the aligning idlers will have a certain impact on the service life of the belt.

Adjust the position of driving drum and reversing drum

The adjustment of driving roller and changing roller is an important part of belt deviation adjustment. Because a belt conveyor has at least 2 to 5 rollers, the installation position of all rollers is perpendicular to the center line of the length direction of the belt conveyor. The adjustment method is similar to that of idlers.
