How Does a Drag Conveyor Work?

How Does a Drag Conveyor Work?A drag conveyor is a versatile option used by many industrial plants to transfer bulk material from one point to another. Also commonly referred to as a drag chain or drag flight conveyor, this popular type of conveyor is characterized by a single- or double-stranded chain of paddles or “flights” that are driven by a motor and pull bulk materials through a channel. Drag conveyors are extremely popular due to their reliability and adaptability.

Bulk Material Handling with Drag Conveyors

Drag conveyors can be inclined or horizontal, depending on the type of paddles being used, and can be partially or fully enclosed. They are exceptionally efficient, as the large paddles allow them to move sizable quantities of material quickly while utilizing minimal power. The spaces between the paddles make top loading of material easy. Additionally, drag conveyors are relatively compact compared to other types of industrial conveyors and don’t take up much floor space, making them a popular and convenient option.

Though most common drag conveyors feature two chains and evenly spaced paddles, en-masse drag conveyors have a single chain with paddles on both sides, allowing them to utilize maximum space in the conveyor and handle larger volumes of material.

How Are Drag Conveyors Utilized?

As mentioned previously, drag conveyors are exceptionally versatile and can be used for a wide array of industries, including chemicals, power and utilities, and construction. They can move all types of bulk material, including:

  • Ash
  • Cement
  • Clinker
  • Coal
  • Food Waste
  • Grains
  • Lime
  • Phosphate
  • Wood Chips
