Trough/Drag Chain Conveyor

Trough/Drag Chain Conveyor

A Trough/Drag Chain Conveyor is a type of material handling system that uses a continuous chain to drag bulk materials through a trough or channel. These conveyors are designed to transport heavy, abrasive, and coarse materials in a variety of industrial applications such as power plants, mining, cement manufacturing, and waste-to-energy facilities. Their robust design and ability to handle a wide range of materials make them a popular choice in environments where efficiency and reliability are critical.

Key Features of Trough/Drag Chain Conveyors

1. Drag Chain Mechanism:
   • The conveyor operates using a continuous drag chain with attachments (also called flights or scrapers) that move material along a trough.
   • High-Tensile Strength Chains: Made of steel or alloy materials that are designed to resist wear and tear from abrasive materials.
   • The chain continuously drags the material through the trough in a controlled, efficient manner.
2. Material Handling Capacity:
   • High-Capacity Design: Trough chain conveyors are capable of handling large volumes of material, from fine powders to larger, more substantial particles like bottom ash, fly ash, or slag.
   • Can be adapted to handle wet or dry materials, depending on the application.
   • Capable of moving materials across horizontal or inclined paths, making them versatile for various plant layouts and space constraints.
3. Durability and Robustness:
   • Heavy-Duty Construction: Designed to withstand harsh conditions, such as high temperatures, abrasive materials, and heavy loads.
   • The trough and chain system are constructed from materials that resist corrosion, wear, and temperature extremes, which is especially important in industries like power plants and metal processing.
4. Flexibility in Design:
   • Modular Construction: The conveyor system can be designed with sections that are flexible in length and can handle various inclinations or turns in the material path.
   • Customizable to Material: Trough/drag chain conveyors can be adapted to suit different material types, sizes, and environmental conditions.
   • Multiple Configurations: Can be designed for both horizontal and inclined installations, or a combination of both, allowing material to be transported efficiently across long distances or up inclines.
5. Low Maintenance:
   • These conveyors have relatively low maintenance requirements compared to other types of conveyors due to the simplicity of their design.
   • Continuous Chain Movement: Since the system uses a continuous chain, the wear and tear are distributed evenly, reducing the need for frequent maintenance or part replacement.
6. Energy Efficiency:
   • Efficient Power Usage: The system is designed for minimal energy consumption, which reduces operational costs in the long term.
   • Variable Speed Control: In some configurations, the system can be equipped with a variable speed drive that adjusts the speed based on material flow, further enhancing energy efficiency.
7. Environmental Control:
   • Enclosed Design: The trough is often fully enclosed to prevent dust generation, which is particularly important when transporting fine materials like fly ash.
   • Can include seals and covers to prevent material spillage and reduce environmental impact.

Applications of Trough/Drag Chain Conveyors

1. Power Plants:
   • Ash Handling: Trough drag chain conveyors are commonly used to handle bottom ash and fly ash in power plants. They efficiently transport these materials from the combustion chamber to ash storage or disposal areas.
   • Fuel Handling: In some power plants, these conveyors can be used for handling coal or biomass fuel for the boiler.
2. Waste-to-Energy (EfW) Plants:
   • Ash and Slag Transport: These conveyors are used to move bottom ash, slag, and other combustion byproducts in waste-to-energy plants.
   • Ensures the continuous removal of waste while maintaining a dust-free and efficient operation.
3. Cement Industry:
   • Raw Material Transport: Trough chain conveyors are used to move raw materials like limestone, coal, and clinker in cement manufacturing plants.
   • Also used for transporting finished cement products from mills to storage or packaging areas.
4. Mining and Metal Processing:
   • Ore and Slag Handling: In mining and metallurgy, drag chain conveyors are used to handle slag, ore, and metal byproducts.
   • These conveyors are ideal for conveying heavy and abrasive materials in metallurgical processes.
5. Sugar Industry:
   • Bagasse Transport: Trough/drag chain conveyors can transport bagasse, a byproduct of sugar cane processing, to storage or disposal areas.
   • Used for moving both wet and dry materials.
6. Agriculture:
   • Grain and Feed Handling: Used for transporting grain, fertilizers, and animal feed in agricultural operations.
   • Can be used to move material in and out of storage silos, feeding systems, or milling operations.
7. Pulp and Paper:
   • Wood Chips and Waste: Trough conveyors handle wood chips, pulp, and other byproducts in the pulp and paper industry, ensuring smooth material handling during production.

Advantages of Trough/Drag Chain Conveyors

• High Capacity: Efficiently transports large volumes of materials, improving throughput in operations.
• Durability: Able to withstand abrasive and high-temperature materials over long periods of operation, ensuring long service life.
• Low Maintenance: The continuous chain design reduces wear and tear, requiring minimal maintenance.
• Space Efficiency: Compact design allows for integration into tight spaces and accommodates horizontal and inclined configurations.
• Energy Efficient: Reduced power consumption with energy-saving features like variable speed drives.
• Dust-Free Operation: Enclosed design and seals minimize dust and spillage, making it suitable for fine materials like fly ash.

Conclusion

A Trough/Drag Chain Conveyor is an ideal solution for handling heavy, abrasive, and high-capacity materials in challenging environments. Its robust construction, low maintenance, and flexible design make it a popular choice in industries such as power generation, waste-to-energy, cement, and mining. Whether you’re handling bottom ash, slag, coal, or scrap materials, a Trough/Drag Chain Conveyor offers a reliable, efficient, and cost-effective method for bulk material transport.
