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.
