1> The blade is too thin. Because the shaftless screw conveyor lacks an intermediate shaft, all the stress points are on the blade, so the thickness of the blade has a very important impact on the actual use of the device. Choosing an appropriate thickness of the spiral blade directly affects the use of the shaftless screw conveyor.

        2> The blade wheelbase is too small, and the diameter of the spiral tube is not selected properly. When conveying powder or flakes, the blade wheelbase is often too small, which causes excessive squeezing force and directly damages the blade. As the shaft rotates, the thicker blade will also cause quantitative damage. Another reason is that the small diameter of the pipe will also cause excessive pressure. Causes severe blade damage. After taking the above two measures, the blade speed can be reduced at the same time. To achieve this effect.

        Shaftless screw conveyor can convey materials that traditional shafted screw conveyors and belt conveyors cannot or are not easy to convey, such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, easy to entangle and block. Materials, materials with special hygiene requirements. The performance characteristics of the shaftless screw conveyor are: Compared with the traditional shafted screw conveyor, the shaftless screw conveyor has the above outstanding advantages due to the use of a centerless design and the use of a solid steel screw to push the material. , Good environmental performance. Compared with the shaft screw conveyor, the weight and cost will be greatly reduced.
