Shaftless Screw Conveyor

  1. Strong anti-winding property, because there is no central axis interference, it has special superiority to convey ribbon material, viscous material and easy winding material.
  2. The screw surface of fully enclosed transmission and easy cleaning, can ensure the sanitation and the material is not contaminated, no leakage.
  3. High torque, low energy consumption. Due to the fact that the screw is not provided with a shaft, the material is not easy to be blocked, so it can run at a lower speed, smooth transmission, reduce energy consumption.
  4. The capacity of transportation is large, it is 1.5 times that of the traditional shaft screw conveyor of the same diameter.
  5. The transmission distance is long, the single machine transmission length can reach 30m, and according to the needs of users, multi-stage series installation can be used to transport materials over long distances.


Shaftless screw conveyor is mainly used for waste water treatment, paper making industry, chemical industry garbage and other industries, strong attached materials, paste-like viscous materials (such as chemical raw materials, waste paper pulp, malt, sludge, etc.) , winding materials (such as household waste).
