Drag conveyors are mechanical devices used for the efficient and reliable movement of bulk materials within industrial and agricultural settings. They are a type of conveyor system designed to handle and transport materials in a horizontal, inclined, or vertical manner using a chain or other linkage mechanisms. Unlike belt conveyors, which use belts to move materials, drag conveyors employ a series of paddles or flights connected to a chain, creating a continuous loop for material transport.

Functions of Drag Conveyors

The fundamental functionality of industrial drag conveyors involves the movement of bulk materials through the use of mechanical paddles or flights. The conveyor chain, driven by a motorized drive unit, propels these paddles, dragging the material along the conveyor path. The flights are positioned in the trough, providing a containment structure that prevents spillage and ensures controlled material flow. Industrial drag conveyors are versatile and can handle a wide range of materials, from fine powders to larger, granular substances.

Types of Used Drag Conveyors

  • En-Masse Drag Conveyors: En-Masse drag conveyors operate on the principle of moving material in a continuous, compact mass. The entire bulk material is conveyed within the housing or casing, with the paddles or flights closely spaced and moving at the same speed. This design ensures that the material remains undisturbed during the conveying process, creating a rolling action that minimizes particle segregation and degradation.
  • Tube-Type Drag Conveyors: Tube-type drag conveyors feature a closed tube as the conveying medium, providing a protective casing around the materials being transported. The chain and flights are contained within the tube, preventing dust or spillage and offering environmental containment. The tube can be round or rectangular, depending on specific application requirements.
  • Round Link Chain Drag Conveyors: Round link chain drag conveyors utilize a continuous chain formed by interlocking round links. This design provides a durable and robust structure for conveying heavy or abrasive materials. The round link chain is driven by sprockets, creating a reliable and efficient material transport system.

Components of Drag Conveyors

  1. Chain: - Drag conveyors employ different types of chains based on the specific application and material handling requirements. Common chain types include:
    • Forged Link Chains: Robust and durable, suitable for heavy-duty applications.
    • Drop Forged Chains: Known for their strength and resistance to wear.
    • Welded Steel Chains: Welded construction for increased strength and reliability.
  1. Flights: - Flights are the protruding attachments or paddles mounted on the conveying chain, responsible for moving and transporting materials. Their primary purposes include:
    • Material Movement: Flights engage with the material and move it along the conveyor path.
    • Preventing Material Spillage: Flights help contain the material within the conveyor, reducing spillage.
  1. Housings: - Housings serve as the protective structure that contains the conveyed material and supports the conveyor components. Key aspects of their importance include:
    • Material Containment: Housings prevent spillage and ensure that the material remains within the conveyor system .
    • Environmental Control: Enclosed housings contribute to dust control, making them suitable for environmentally sensitive areas.
    • Structural Support: Housings provide support for the chain and flights, ensuring proper alignment and operation.
  1. Drive Systems: - The drive system is responsible for powering the drag conveyor. Common drive mechanisms include:
    • Direct Drive: The motor is directly connected to the drive shaft, providing a straightforward and efficient power transfer.
    • Chain and Sprocket Drive: Sprockets are used to transmit power from the motor to the conveyor chain.

Comparing Chain Drag Conveyors to Other Material Handling Solutions

Chain drag conveyors are a type of material handling equipment that plays a crucial role in various industries. Lets explore how used chain drag conveyors measure up against other common material handling solutions.

Efficiency:

  • Chain Drag Conveyors: Chain drag conveyors are known for their high efficiency in transporting bulk materials horizontally or slightly inclined. They provide a continuous flow, ensuring a steady and controlled movement of materials.
  • Belt Conveyors: Belt conveyors are also efficient for bulk material handling, but they may not be as suitable for certain types of materials or applications due to their design.
  • Screw Conveyors: Screw conveyors are effective for moving materials, especially those with a uniform particle size. However, they may have limitations in handling larger, irregularly shaped materials.

Durability:

  • Chain Drag Conveyors: Chain conveyors are robust and durable, making them suitable for heavy-duty applications. They can withstand the rigors of handling abrasive or corrosive materials.
  • Belt Conveyors: Belt conveyors are durable, but they may experience wear and tear, especially in applications involving sharp or abrasive materials.
  • Screw Conveyors: While generally durable, screw conveyors may have limitations when dealing with materials that can cause excessive wear on the screw flights.

Flexibility:

  • Chain Drag Conveyors: Chain conveyors offer flexibility in terms of layout and design. They can navigate around obstacles and handle multiple discharge points.
  • Belt Conveyors: Belt conveyors are flexible and can be adapted to various configurations, making them suitable for different layouts.
  • Screw Conveyors: Screw conveyors may have limitations in terms of flexibility, especially in complex layouts or when dealing with changes in elevation.

Suitability for Specific Applications:

  • Chain Drag Conveyors: Ideal for handling bulk materials like grain, cement, and other granular or powdery substances. They are commonly used in industries such as agriculture, mining, and manufacturing.
  • Belt Conveyors: Suitable for a wide range of industries, including mining, manufacturing, and packaging. They excel in moving larger quantities of materials over longer distances.
  • Screw Conveyors: Commonly used for transporting bulk materials with a consistent particle size, such as grains, powders, and granular materials.

Applications of Surplus and Used Drag Conveyors

Industries that Commonly Use Drag Conveyors:

  • Cement Industry: Drag conveyors are vital in cement manufacturing, transporting raw materials like limestone and gypsum to the production process, as well as conveying the finished product for packaging or distribution.
  • Mining Operations: Widely used in mining to transport ores, minerals, and other extracted materials efficiently.
  • Chemical Processing: Applied in the chemical industry for handling various chemicals and raw materials.
  • Recycling Facilities: Used to transport recycled materials, such as glass, plastic, or metal, in recycling processes.
