How to Avoid Conveyor Belt Top Cover Cracking

Understanding and Mitigating Conveyor Belt Damage

Screen Shot 2024-04-03 at 12.29.06 PMMany types of damage to conveyor belts can be attributed to either the materials being transported or misalignments within the structure's components. However, some issues are inherent to the design of the conveyor system itself.

One such critical issue is top cover cracking. This problem can lead to significant damage to other components of the belt and is typically caused by errors made during the selection of the belt itself. The top cover of any conveyor belt is constructed from specific materials, each with its own unique strengths and limitations. Some belts are engineered to excel in abrasion resistance, while others prioritize flexibility, depending on the operational requirements.

Regardless of the chosen material, every belt has strict limits on its bending capabilities, which determine the minimum radius it can comfortably wrap around pulleys of various sizes. This bending capability is influenced by factors such as the number of layers or the thickness of the material used in the belt's construction.

When belts are wound too tightly around pulleys, the stress eventually causes cracks to form in the top cover. These cracks expose the underlying layers to potential damage, compromising the belt's integrity and longevity. Therefore, it is crucial for companies to meticulously assess dimensional requirements and operational needs when considering a belt change. Failing to do so can nullify many of the anticipated benefits associated with switching belts, potentially leading to increased downtime and maintenance costs.
