Tubular Drag Conveyors

Tubular drag conveyors are mechanically driven conveyors that ‘drag’ material along inside of a tube. They are designed to transfer flowable bulk materials from in-feed points to discharge points through a totally sealed tubular system, ensuring the dust free, hygienic transfer of material. At the heart of every tubular drag conveyor is the conveyor chain and disc or cable and disc assembly. The discs are spaced along the cable or chain and its ends connect to each other to form an endless loop pulled by a motor driven sprocket within an enclosed tube. Changes in direction are facilitated by bends in the tubing or by corner housings for tighter radii.

Spiroflow offers a wide range of tubular drag conveyor construction materials and assemblies to meet the demands of various dry bulk products. Our tried, tested and proven cable and chain drag conveyor designs effectively satisfy all applications.


Why choose tubular drag conveyors to move your material?

  • Totally enclosed, dust-free, contamination-free handling
  • Discs molded onto hygienic chain
  • Handles hot, cold, dry hygroscopic or temperature sensitive materials
  • Minimizes material residence and build-up
