What are mining conveyor belts and how to choose the best one for your operations?
Is there any specific rubber conveyor belt for the mining operations?
While everything is working in unison, efficient conveying is what matters the most.
Smart buyers must know well about specific conveyor belt types before buying. With advancements in technology, a rubber conveyor belt is getting upgraded every day. But, if you are looking for compact information on a belt and conveyor, here you go:
What Is A Mining Conveyor Belt?
A mining rubber conveyor belt is a moving strip of rubber that is run by pulleys. The key components of a conveyor belt for mining include:
- A Rubber Cover
- Pulleys
- Motors That Power The Belt And Conveyor
- Rollers With Bearings
- Tensioning Systems
Mining rubber conveyor belt has a similar structure to the conveyor belts used in other core industries like construction or manufacturing. However, since mining includes rigorous application and exposure to extreme temperatures, a mining conveyor belt must have a durable cover- heat and fire-resistant.
5 Uses of Rubber Conveyor Belt In The Mining Industry
Ore and Waste Rock Transportation
A Fundamental application of a rubber conveyor belt in mining is the transportation of materials extracted. They move ore, coal, and other valuable minerals from the mines to processing plants or stockpiles. This minimizes the need for manual labor or numerous mining trucks, significantly reducing costs as well.
A mining belt and conveyor can operate in both horizontal and inclined positions, making them adaptable to different mining environments, like underground mines and open-pit operations.
Since the materials mined have sharp edges, here you should choose a conveyor belt that has strong anti-abrasive properties. Otherwise, you may have to frequently replace conveyor belt types made of low-grade rubber.

Sorting and Processing of Mined Materials
A rubber conveyor belt helps with the sorting and processing of mined materials. They transport crushed rock, coal, and other minerals through various processing stages. Some of the processing stages include: crushing, screening, washing, and sizing. This allows for the quick separation of valuable minerals from waste rock.
Moreover, a belt and conveyor here ensure that the final product meets the required specifications.
Modern conveyor belts can be equipped with sensors and automated systems to identify and remove unwanted materials. But, during the sorting of mined materials, the rubber cover of the conveyor belts can get affected by continuous running.
The friction generated from the pulleys slowly degrades the bottom cover, as well. A Pulley Lagging Sheet can safeguard your rubber conveyor belt here.
Stockpiling and Loading of Mined Materials
The belt and conveyor play a significant role in stockpiling and loading mined materials. They convey processed materials to designated stockpiles for temporary storage. They also move mined materials directly onto trucks, trains, or ships for transportation to processing facilities or consumers.
This seamless movement of mined materials reduces manual handling, reducing dependency on heavy machinery. Additionally, conveyor belts can be designed with specific features, such as a stacker and reclaimer, to manage stockpiles with fine precision.
However, even with the best-quality rubber conveyor belt, you may face long production downtime. Do you know you can easily manage some of the issues? 7 problems in rubber conveyor belts and their solutions!
Conveying Over Long Distances
Did you know the longest single conveyor belt in the world goes to the 51-kilometer (31.6-mile) system located in Western Australia (Guinness Book of World Records)? This belt transports bauxite ore from the Mount Saddleback mine to the Worsley refinery near Collie.
In some mining operations, conveying materials over long distances is essential. This is where overland conveyor systems come into the picture. These massive conveyor belts stretch for kilometers, efficiently moving large quantities of materials across vast distances.
Overland conveyors offer a cost-effective and environment-friendly alternative to traditional mining trucks.
As per our research as a trusted supplier conveyor belt, the right conveyor belt types reduce reliance on road infrastructure, minimize fuel consumption and emissions, and contribute to a more sustainable mining operation.
Elevating Materials to Different Levels
A rubber conveyor belt can be used for more than horizontal transportation. They can also be inclined or even vertical, allowing them to elevate materials to different levels within a mine or processing center. This is important for moving materials between different processing stages or conveying them to stockpiles located at higher elevations.
Inclined conveyor belts are designed to handle the additional challenge of gravitational pull, ensuring safe upward material movement.
How to Choose a Mining Rubber Conveyor Belt?
Keep in mind these 3 major factors while buying a mining conveyor belt: Abrasion Level, Heat Resistance, and Fire Resistance.
Abrasion Level: Abrasion affects the rubber cover, slowly weakening it. Iron ore, copper, lignite, limestone, and blast furnace slag are highly abrasive. In quarry and mining, a rubber conveyor belt also conveys fine materials like slacked lime. The Duratuf General Purpose Rubber Conveyor Belts have tested anti-abrasive strength and are available in three types.
