Conveyor belt systems play a crucial role in the mining industry, making operations more efficient and less costly. A mining conveyor belt transports mined materials from the site to loading areas or processing facilities. Choosing the right mining conveyor belt depends on the needs of your business.

Understanding Mining Conveyor Belts

At the heart of a conveyor system lies the mining conveyor belt, essential for moving ore and various materials from the mining site to processing units or loading zones. These belts, powered by motors running on electricity or alternative sources, come in various compositions, including plastic or rubber compounds, fabric materials, and steel cables. Supported by rollers, these belts move materials efficiently and safely at a set speed.

Composition of Conveyor Belts

Typically, a conventional conveyor belt comprises three layers:

  • The top layer or cover supports the product during transit.
  • The middle layer, also known as the carcass, provides additional support, often made of metal or woven fabric.
  • The bottom cover completes the belt’s structure.

Types of Conveyor Belts

Selecting the correct conveyor belt system type is vital for ensuring safe and efficient operations, as using the wrong type can lead to detrimental consequences and unplanned downtime. The various conveyor belt types include:

  • Straight-warp: Ideal for tunnelling, used in rock quarries and crushers. They feature impact and tear resistance, with yarns and polyamide on both sides.
  • Multi-ply: Characterized by multiple fabric layers separated by rubber, these belts are durable and suitable for underground applications.
  • Steel-cord: Employing steel cables along the belt’s length, these are designed for underground applications.
  • Solid woven belts: More common in Europe and Asia, less so in the U.S.
    Heat-resistant: Built to withstand high temperatures.

Choosing the Right Mining Conveyor Belt

Application and environment are top considerations when selecting a mining conveyor belt. Consider tensile strength requirements, cover thickness, and type based on the material transported and loading method. For example, conveyors in temperature-controlled warehouses transporting light materials have different demands than those moving heavy products in underground mines.

Differentiate between above-ground and underground belts. Above-ground belts, typically made of highly flammable petrochemicals, pose a safety hazard if used underground. In contrast, underground mining belts incorporate flame-resistant materials and special agents to reduce friction and increase fire resistance.

For surface or above-ground belts, consider the properties of transported materials, including humidity levels, granularity, and abrasion characteristics. The nature of transported materials significantly affects belt lifespan; abrasive materials can damage the belt more quickly.

Additional Considerations

  • Service Life: Consider durability based on your environment; belts in mines and quarries have different demands than factory lines.
  • Temperature: High-temperature materials can damage belts; select a belt with appropriate thermal properties.
  • Fireproofing: For underground conveyors, ensure compliance with fire resistance requirements like MSHA Part 14.
  • Pulley Diameter: The recommended diameter varies depending on the belt fabric thickness.
  • Corrosion-Resistance: Important in fluctuating environments, mainly underground.
  • Belt Width & Length: Know your sizing requirements, as belts vary significantly in width and size based on application.
