For the belt conveyor
, the conveyor belt occupies a very important position. It is both the traction component and the bearing component, and the price is expensive, accounting for about 30%~50% of the total cost of the belt conveyor. Once the conveyor belt is thinner due to wear, it will lead to reduced strength, shortened service life, belt deviation and other failures. This paper analyzes several main wear forms and puts forward some maintenance measures combined with production practice.
I. Wear and tear between feed trough and conveyor belt
The feeding trough is in close contact with the conveyor belt, and its design and installation have great influence on the wear of the conveyor belt, which is the main manifestation of the wear of the conveyor belt.
Formation reasons: when the material is fed, it has an impact on the conveyor belt, especially when the Angle between the material and the conveyor belt is greater than or equal to 90, it will cause strong wear to the conveyor belt;
Maintenance measures: In order to minimize the wear of the conveyor belt of the feed port, the structure design of the feed port should meet the following conditions: the feed direction should be the same as that of the conveyor belt, and the movement speed of materials in the feeding process should be almost the same as that of the conveyor belt; In addition, the chute and guide chute should be securely secured so that they are properly positioned on the conveyor belt and the guide bottom should not be too close to the conveyor belt.
Two, the wear between the drum and the conveyor belt
The reversing drum is located at the end of the conveyor, and the conveyor belt rotates with the reversing drum, making the lower conveyor belt become the upper conveyor belt to transport materials.
Formation reasons: Wear is mainly due to the sundries between the conveyor belt entering, adhering to the roller, causing local radius deformation and wear.
Maintenance measures: Install a scraper on the surface near the reversing drum. The scraper and the receiving plate are welded together in one piece. The receiving plate is bolted to the conveyor frame, and the scraper and roller have a certain dip Angle to increase the scraping capacity.
In addition, in order to solve the problem of material leakage in the unsupported section before reversing the drum, baffle can be installed in the unsupported section to reduce material leakage.
