What are the hazards of the surface damage of heat-resistant conveyor belts?

Jul 09, 2019

The various surface damages generated by the heat-resistant conveyor belt during operation have many adverse effects on the safe operation of the heat-resistant conveyor belt. What are his main hazards?


 1. The conveyor belt is thinned: the heat-resistant conveyor belt is not easy to be lapped after being thinned, and the surface of the heat-resistant conveyor belt is damaged, so that the thickness is thinned. When the head ends are overlapped, the thickness of the joint is different, and the joint is in operation. The position and the roller produce a strong scratch, which not only wears the roller, but also shortens the joint life, especially when the new belt is overlapped with the old belt. For heat-resistant conveyor belts that are joined by vulcanization, lap joints are more difficult due to different thicknesses.

     2. The strength of the conveyor belt is reduced: the damage of the heat-resistant conveyor belt reaches a certain level, especially the depth and core layer after the damage of the cover layer, which directly affects the tensile strength of the heat-resistant conveyor belt and reduces its strength. When the steel cord core heat-resistant conveyor belt is damaged to the core layer, it may cause the steel cord core to rust and lose its proper strength. In the course of operation, the heat-resistant conveyor belt with poor strength encounters a sudden increase in load. For example, when the load is started and the cassette is loaded, the heat-resistant conveyor belt breakage is likely to occur.

     3, the conveyor belt life is shortened: the damage of the heat-resistant conveyor belt, firstly make the cover layer thin or even expose the core layer, so that the heat-resistant conveyor belt is prematurely damaged, reducing the service life of the heat-resistant conveyor belt, increasing the mine Transportation costs. For the heat-resistant conveying belt with different degrees of wear on both sides of the center line of the heat-resistant conveyor belt, the service life of the heat-resistant conveyor belt is further reduced due to the change of the local tensile strength.

    4. Conveyor belt deviation: When the damage degree on both sides of the center line of the heat-resistant conveyor belt is different, the stretching rate on both sides often changes, which directly causes the heat-resistant conveyor belt to run off during operation.
