How to prevent screw conveyor stuck / jam ?

Screw conveyor is also called auger conveyor. It is a commonly used conveying equipment. It is widely used in chemical, building materials, metallurgy and grain industries to transport powdery, granular and small materials with low viscosity and difficult to change. In actual use, there are still some serious problems, such as accidents, vibration, jamming, transmission parts damage and so on. 

To solve the problem of the screw conveyor jam, it is necessary to solve the problem before the material enters the spiral. It is essential to prevent the debris from entering the spiral. For example, the granular or powdery material should be added with a mechanical screen in front of the conveyor, or you can try to change the spiral and The inner shell is matched, for example, the inner shell is changed so that the spiral edge is embedded in the spiral spiral track of the inner shell to form a seamless spiral conveying, and the material and the foreign matter are in a completely closed spiral space, so as to achieve the effect of no jamming.
