Samsara's Tubular Chain Conveyors, also known as Disc or Drag Conveyors, gently transport bulk materials through smooth stainless steel tubing using low-friction polymer discs attached to stainless steel chains. Driven by a wheel at one end and tensioned by a wheel at the other, this design allows for single or multiple inlets and outlets. Conveyor tubing can be routed horizontally, vertically, or at any angle, passing through small holes in walls or ceilings. The modular components enable easy addition, removal, or relocation of inlets and outlets, and the circuit can be lengthened, shortened, or re-routed as needed.
