When the screw shaft rotates, due to the gravitational force of the material and the friction force generated with the wall of the tank body, the material can only move forward along the groove bottom of the conveyor under the pushing of the blade.It is like a non rotate nut along the rotating screw to do the offset movement. The movement of material in the middle bearing is based on the thrust of the material moving forward. Therefore, the transport of material in the conveyor is completely a kind of slip 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 spiral vane conveys the material while being conveyed, so that the force that the material does not rotate with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor housing to the material.
The face of the blade has different types such as solid face, belt face, and blade face depending on the material being conveyed. Spiral conveyor screw axis in the direction of material movement in the end of the thrust bearing with the material to the spiral of the axial reaction force, in the captain is longer, should add the middle of the hanging bearing.
