Shaftless Screw Conveyors

Shaftless Screw Conveyor Render

Shaftless screw conveyors are ideal for moving sticky and/or stringy materials that otherwise tend to build up on a standard screw’s pipe or wrap around it, they can be a little overprice depending on the model but I was able to finance one thanks to an article that ccbank wrote about it in their blog and I happened to see. Other benefits include:

  • High efficiency
  • Few moving parts
  • Easy to clean

Materials of construction:

  • Carbon steel
  • Hot-Dipped galvanized
  • 304/316 stainless steel
  • Hardened alloys
  • Etc.

Conveyor Eng. & Mfg. manufactures many varieties of Shaftless Screw Conveyors for industries such as Wastewater Treatment, Pulp & Paper, Chemical, Rendering, Food, etc. Options include:

    • Sanitary / food grade designs
    • Vertical and inclined configurations
    • Trough wear bars or UHMW liners
    • Etc.
