With the increase of usage time, the conveyor belt will wear, which will not only reduce its strength, but also shorten its service life, and may cause problems such as conveyor belt deviation. This article will analyze the forms of conveyor belt wear and its causes in detail, and propose corresponding solutions.
1. Wear between the feed chute and the conveyor belt
Causes:
1. Material impact: When the material falls from a high place, it will have a large impact force on the conveyor belt below. If the angle between the feed chute and the conveyor belt is large, this impact force will be more obvious, and in the long run, it will cause different degrees of wear on the upper surface of the conveyor belt.
2. Friction caused by close contact: In order to reduce the scattering of materials, a guide plate is usually set to guide the material to fall smoothly onto the conveyor belt. However, if the guide plate is designed to be too close to or directly in contact with the conveyor belt, additional friction will be generated during the passage of the material, thereby accelerating the loss of the conveyor belt surface.
3. Hard foreign matter damage: Sometimes the raw materials may be mixed with stones or other hard objects. Once these hard objects are stuck at the feeding port, they will not only cause physical scratches on the conveyor belt, but may also cause more serious local damage.
Solution:
Adjust the feeding direction: Ensure that the direction of the feeding trough is consistent with the movement trajectory of the conveyor belt, and control the feeding speed to make it as close as possible to the actual running speed of the conveyor belt, which can effectively reduce the additional pressure caused by the speed difference.
Add a bar screen device: Install a bar screen of appropriate specifications inside the feeding trough to allow smaller and softer materials to pass through first and fall on the conveyor belt, thereby providing a natural "cushion" for the subsequent large-particle items to play a buffering role.
Optimize the structural layout: Appropriately reduce the height of the feeding trough relative to the horizontal plane to reduce the speed of the material falling; in addition, install special buffer equipment (such as buffer beds or rollers) at the receiving end of the conveyor belt to further absorb the impact force and protect the belt from damage.
The above measures can significantly improve various forms of wear problems caused by improper feeding of the conveyor belt, extend its service life, and improve the working efficiency and safety of the entire system.
