Choosing the Right "Tooth Profile" for Chevron Conveyor Belts Is Critical! A Summary of Adaptation Solutions for Different Inclinations

Selecting the correct tooth profile is the key to ensuring chevron conveyor belts operate stably—especially when dealing with different conveying inclinations. The wrong tooth profile can lead to problems like material slipping, scattering, or even belt damage, while the right match keeps the conveying process smooth and efficient.

When the conveying inclination is relatively small, usually between 10° and 15°, a low-tooth chevron profile is the most suitable choice. This type of tooth has a shorter height and a gentler slope, which is ideal for transporting materials with good fluidity, such as grain, fertilizer, or small granular coal. The low teeth prevent unnecessary material accumulation while reducing friction between the material and the belt surface, making it easier to clean the belt after use. It also avoids excessive resistance during operation, which helps save energy consumption of the conveying system.

For medium inclinations, generally ranging from 15° to 25°, a medium-tooth chevron profile works best. This tooth profile has a moderate height and a steeper angle than low teeth, providing stronger grip on materials. It is perfect for conveying materials with moderate viscosity or irregular particles, like crushed ore, limestone, or mixed aggregates. The medium teeth can effectively prevent materials from sliding backward along the inclined surface, even when the conveying speed slightly fluctuates. At the same time, it balances the capacity of material holding and the smoothness of operation, avoiding both material scattering and excessive wear on the tooth edges.

When facing large inclinations—often over 25° and even up to 35° in some cases—a high-tooth chevron profile or a double-chevron (herringbone) profile is necessary. High-tooth profiles have tall, sharp teeth that create strong "barriers" to hold materials firmly, which is essential for conveying bulk, heavy, or highly viscous materials such as wet coal, iron ore, or slag. Double-chevron profiles, with teeth arranged in a crisscross pattern, not only enhance anti-slip performance but also reduce the belt’s lateral tension, preventing belt deviation during high-inclination operation. However, it’s important to note that high-tooth or double-chevron belts require more careful maintenance—regularly checking for tooth wear or material blockage between teeth to avoid tooth breakage.

In addition to matching the tooth profile to the inclination, you also need to consider the material’s properties (such as moisture content and particle size) and the conveying speed. For example, if the material is particularly wet and sticky, even at a medium inclination, a high-tooth profile may be needed to prevent material adhesion and slipping. By comprehensively combining these factors, you can maximize the performance of chevron conveyor belts and avoid common operational issues.
