working principle
The shaftless screw conveyor is used for conveying medium and fine grids in sewage treatment plant. The net distance between the grids is 50 mm, and the screen slag of the filter press and other materials are transported. Good environmental performance. The use of fully enclosed conveying and easy to clean spiral surface can ensure the environmental hygiene and the delivered materials are free from pollution and leakage. Large torque and low energy consumption. Because the screw has no shaft, the material is not easy to be blocked and the discharge port is not blocked, so it can run at a lower speed, drive stably and reduce energy consumption.
