What causes the mining belt conveyor to scatter materials?

There are many reasons why mining belt conveyors scatter materials, mainly including the following aspects:

1.Spreading material at the transfer point: This usually occurs at the drop hopper and guide trough. When the belt conveyor is severely overloaded, the material may rush out at the guide trough, causing material to spread. In addition, if the material blocking rubber skirt of the guide trough is damaged or unreasonably designed, such as being far away from the belt or the rubber skirt is too long, it may also cause material to spill out.

2.Belt deviation: If the belt deviation occurs during operation, material may be spilled from one side of the belt. Reasons for misalignment may include uneven belt tension, improper installation of drums or rollers, incorrect belt joints, or aging and deformation of the belt.

3.The belt in the concave section is suspended: When the belt conveyor operates when the curvature radius of the concave section is small, the belt may be suspended. At this time, the groove formation of the belt changes and materials may be spilled.

4.Problems with the cleaning device: The cleaning effect of the cleaning device is not good, which may cause materials to stick to the belt and scatter as the belt runs.

5.Damaged rollers: Damage or falling off of the rollers may also cause materials to be spilled during transportation.

6.Problems with the material itself: When the material has too high humidity or contains sticky components, it is easy to stick to the belt during transportation, causing material to scatter.

7.Equipment design or installation problems: Unreasonable design or improper installation of the conveyor, such as insufficient Conveyor Belt tension, incorrect roller position, etc., may also lead to material spillage.

To sum up, there are many reasons why mining belt conveyors spread materials, involving many aspects such as equipment design, installation, maintenance and material characteristics. In order to solve the problem of spreading materials, comprehensive analysis and treatment from these aspects are needed.
