1. Friction between the idler and the conveyor belt is a common issue. The lower cover rubber of the rubber conveyor belt experiences friction from both the centering roller and the forward-inclined roller. This leads to wear, especially at the transition points between the grooved rollers and the drum, as well as on the convex sections of the conveyor belt. Over time, this can cause structural damage and reduce the lifespan of the belt.
2. The cleaner, or scraper, also contributes to belt wear. Normally, the wear caused by the cleaner is even across the belt’s surface. However, if a hard steel plate is used as the cleaning blade and not handled properly, it can cut through the rubber layer, removing material beyond just the dirt. Additionally, if foreign objects get caught between the cleaner’s tip and the belt, they can create deep scratches that run the entire length of the conveyor belt, leading to more serious damage.
3. The frame of the conveyor system can also come into contact with the belt, causing friction and misalignment. This often happens due to manufacturing or installation defects, or improper use over time. When the belt deviates from its intended path, it can rub against the frame, leading to uneven wear and potential tearing of the belt’s edges.
4. The guide groove baffle can cause specific types of wear on the conveyor belt. This kind of damage usually occurs when the baffle is not properly designed or maintained. However, with improved design techniques and regular maintenance, this type of wear can be significantly reduced or even prevented entirely. Ensuring proper alignment and using high-quality materials for the baffles can help extend the life of the conveyor belt and improve overall system efficiency.
