Screw Conveyor Spiral Conveyor

The working principle of the Spiral Conveyor is to use the gravity of the material and the friction force generated by the tank wall.
The movement of the material in the intermediate bearing depends on the thrust of the material advancing behind it. Therefore, the transportation of materials in the conveyor is completely a sliding movement.
In order to make the screw shaft in a more favorable tension state, the drive device and the discharge port are generally placed at the same end of the conveyor, and the feed port is placed as close as possible to the tail of the other end.
The rotating screw blade pushes the material for conveying, and the force that prevents the material from rotating with the screw conveyor blade is the weight of the material itself and the frictional resistance of the screw conveyor casing to the material.
According to the different conveying materials, there are solid surface, belt surface, blade surface and other types of blade surface type. The screw shaft of the screw conveyor has a thrust bearing at the end of the material moving direction to give the screw axial reaction force with the material. When the length of the machine is long, an intermediate hanging bearing should be added.
