Hey there! As a supplier of mining conveyors, I've seen firsthand the importance of choosing the right belt type for the job. Different mining operations have different requirements, and the type of belt you use can make a big difference in terms of efficiency, durability, and safety. In this blog post, I'm going to break down the different belt types used in mining conveyors and their features.
1. Fabric Belts
Fabric belts are one of the most common types of belts used in mining conveyors. They're made from layers of fabric, usually cotton, polyester, or nylon, which are then coated with rubber to provide strength and flexibility.
Features:
- Flexibility: Fabric belts are highly flexible, which allows them to bend around pulleys and idlers easily. This makes them suitable for conveyors with complex layouts.
- Cost - effective: They are generally more affordable compared to some other belt types, making them a popular choice for many mining operations, especially those on a budget.
- Good Tensile Strength: The fabric layers give these belts good tensile strength, which means they can handle a reasonable amount of load without breaking. However, their strength is limited compared to some steel - cord belts.
Fabric belts are great for transporting light to medium - sized materials such as coal, sand, and gravel. If you're looking for a reliable and cost - effective solution for your mining conveyor, fabric belts might be the way to go.

2. Steel - Cord Belts
Steel - cord belts are designed for heavy - duty applications. They consist of high - strength steel cords embedded in a rubber compound.
Features:
- High Tensile Strength: The steel cords give these belts extremely high tensile strength, allowing them to carry very heavy loads over long distances. This makes them ideal for transporting large amounts of ore or coal in mines.
- Low Stretch: Steel - cord belts have very low stretch characteristics. This means that they maintain their length and tension more effectively, reducing the need for frequent adjustments.
- Resistance to Impact: They are more resistant to impact damage compared to fabric belts. When large rocks or heavy materials are loaded onto the conveyor, steel - cord belts can withstand the impact without getting damaged easily.
However, steel - cord belts are more expensive than fabric belts. But if your mining operation involves moving large volumes of heavy materials over long distances, the investment in steel - cord belts is often worth it.
3. Chevron Belts
Chevron belts have a unique pattern on the surface, which looks like chevrons or V - shapes. This pattern is designed to prevent materials from sliding off the belt, especially when the conveyor is inclined.
Features:
- Anti - Slip: The chevron pattern provides excellent grip on the materials being transported. This is crucial for inclined conveyors, as it ensures that the materials stay on the belt and are transported safely to their destination.
- Versatility: Chevron belts can be used for a variety of materials, including wet or sticky substances. The pattern helps to keep these materials from sticking to the belt and also prevents them from sliding down.
- Increased Capacity: By preventing material spillage, chevron belts can increase the overall capacity of the conveyor. You can move more materials in a single pass, which improves the efficiency of your mining operation.
If you have an inclined conveyor in your mine, chevron belts are a must - have. They can significantly improve the performance of your conveyor system. Check out our Tripper Conveyor page to see how chevron belts can be integrated into different conveyor setups.
4. Sidewall Belts
Sidewall belts are another type of belt designed for inclined or vertical conveying. They have vertical sidewalls along the edges of the belt, which prevent materials from falling off.
Features:
- Vertical Conveying: Sidewall belts are capable of vertical or near - vertical conveying, which is not possible with regular flat belts. This makes them ideal for transporting materials between different levels in a mine.
- High Capacity: The sidewalls increase the cross - sectional area of the belt, allowing it to carry more materials. This results in higher throughput and improved efficiency.
- Customizable: The height and shape of the sidewalls can be customized according to your specific requirements. You can choose the right sidewall design to suit the type of material you're transporting and the angle of the conveyor.
Sidewall belts are a great solution for mines with complex vertical or inclined conveying needs. They offer a reliable way to move materials between different levels without the risk of spillage.
5. Tubular Belts
Tubular belts are a relatively new innovation in the mining conveyor industry. They form a tube around the material being transported, enclosing it completely.
Features:
- Containment: Tubular belts provide excellent containment of the materials. This is especially important when transporting hazardous or dusty materials, as it prevents them from spilling or being released into the environment.
- Reduced Friction: The tubular shape reduces friction between the belt and the idlers, which can result in lower energy consumption. This makes tubular belts more energy - efficient compared to some other belt types.
- Flexibility in Layout: Tubular belts can be routed in a more flexible way compared to flat belts. They can be curved horizontally and vertically, allowing for more complex conveyor layouts.
If you're concerned about environmental impact and energy efficiency, tubular belts are a great option. You can find more information about conveyor components on our Roller Idler Conveyor page.
Conclusion
Choosing the right belt type for your mining conveyor is crucial for the success of your operation. Each belt type has its own unique features and advantages, and the choice depends on factors such as the type of material you're transporting, the distance of the conveyor, the angle of inclination, and your budget.
