The most likely thing to happen during the use of the spiral blade conveyor is the sweeping phenomenon. Once the sweeping occurs, it indicates that the screw conveyor is about to end its life. Sweeping is generally related to the materials being conveyed. When the material is too viscous and locked in the wall of the screw auger, it will cause uneven squeezing force and deviation, resulting in sweeping. There is also a scan that the gap between the spiral blade and the inner tube wall of the conveyor is too small, which leads to deviation.

It is also common for conveyor blades to be produced irregularly and there will be sweeping. If the shaft hole in the spiral blade is too small, the conveyor will be sweeping if the length of the conveyor is too long. In addition, the speed will affect the pitch and so on.

How to avoid the phenomenon of church sweeping. First of all, we must determine the outer diameter, inner diameter and pitch of the spiral blade according to the nature of the material. Generally speaking, the inner diameter should be as large as possible to effectively prevent the deviation of the centrifugal force caused by the blade operation. Second, the speed should be moderate, not too fast or too slow. After finishing work, clean the contaminated objects in the auger blades.

To improve the production quality of blades, thick tube walls are used to prevent operation deformation. When the blade is welded to the shaft, both ends should be leveled, and then welded on both sides and welded at the same time to minimize the impact of welding deformation on the blade. If this will cause the deformation to exceed the standard, you can take the blade and the shouted shaft to a lathe to turn the outer diameter and it will be concentric.
