When the screw shaft rotates, due to the gravity of the material and its friction with the wall of the trough body, so that the material can only be pushed in the blade along the conveyor bottom of the trough to move forward, as if the situation can not rotate the nut along the rotating screw for the same translational movement. Material in the middle of the bearing movement, is to rely on the back of the advancing material thrust. Therefore, the transport of materials in the conveyor, is entirely a kind of sliding movement. In order to make the screw shaft in a more favourable state of tension, generally will drive the device and discharge port placed in the same end of the conveyor, and the inlet as far as possible on the other end of the tail near. Rotating screw blades will push the material and transport, so that the material does not rotate with the
Screw Conveyor blade force is the weight of the material itself and the screw conveyor casing friction resistance of the material. According to the different materials conveyed, there are solid surface type, belt surface type, blade surface type and other types. Screw conveyor screw shaft in the direction of material movement at the end of the thrust bearing in order to follow the material to the screw axial reaction force, in the longer length, should be added in the middle of the hanging bearing.
