The principle of screw conveyor is that the rotating spiral vane will carry the material through the screw conveyor, so that the material does not rotate with the screw conveyor blade force is the weight of the material and the screw conveyor chassis friction resistance of the material.
Spiral Conveyor shaft welding spiral blade, the surface of the blade according to the different materials have solid face, belt type, leaf surface type. Screw conveyor screw shaft in the direction of the material movement of the end of the thrust bearing with the material to give the axial force of the helix, in the captain longer, should be added intermediate hanging bearing.
