Drag Chain Conveyors

Drag Chain Conveyors

Drag Chain Conveyors are heavy-duty, mechanically driven systems engineered to transport bulk materials with exceptional reliability across horizontal, inclined, or vertical paths. Featuring a continuous loop of robust chain—equipped with flights, paddles, or scrapers—these conveyors drag materials through an enclosed trough, ensuring minimal spillage and dust emission. Built to handle abrasive, high-temperature, or sticky substances, they excel in demanding environments like boiler fuel feeding systems, where precise and consistent delivery of fuels such as coal, biomass, or ash is critical. Available in single- or double-strand configurations with customizable chain types (e.g., chain bush or Redler chains), these conveyors offer unparalleled durability and adaptability, making them a cornerstone of material handling in industries ranging from power generation to food processing.

  • Boiler Systems: Widely used in power plants and industrial facilities to feed various fuels into boilers, handle ash (fly ash and bottom ash), and manage high-temperature materials.
  • General Industrial Use: Transporting grains, cement, coal, ores, and other bulk solids in mining, agriculture, and manufacturing.
  • Food-Grade Applications: Suitable for conveying food-grade materials like cereals, sugar, and flour when constructed with appropriate materials and finishes.
  • Coal: A primary fuel for boilers, requiring durable chains to handle abrasive properties.

  • Carbon Steel: Standard for general-purpose, cost-effective applications.
  • Stainless Steel: Ideal for food-grade or corrosive environments (e.g., ash handling or MSW).
  • Abrasion-Resistant Alloys: For high-wear fuels like coal or petcoke.
  • Customizable flight/paddle designs for specific material handling needs.
  • Enclosed design minimizes dust and material loss, critical for boiler fuel delivery.
  • Energy-efficient operation with low horsepower requirements.

Various Chains Available:

  • Chain Bush: Rollerless bush chains for high-load, abrasive materials, offering durability and low friction.
  • Redler Chain: A specialized drag chain known for handling granular and powdery materials efficiently, commonly used in boiler feed systems.
  • Single or Double Strand Configurations: For varying load capacities and stability.
