When the screw shaft rotates, the material can only move forward along the groove bottom of the conveyor under the push of the blade due to the gravity of the material and the frictional force between it and the wall of the groove body. It is the same as the translational motion of the rotating screw. The main forward power of the material comes from the force that the helical blade rotates in the axial direction to move the material upward and forward along the tangential direction of the blade.

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,The force that keeps the material from rotating with the blades of the Spiral cooling conveyor from China manufacturer is the weight of the material itself and the frictional resistance of the casing of the Spiral cooling conveyor from China manufacturer to the material. According to the different conveying materials, there are solid surface, belt surface, blade surface and other types of blade surface type. Spiral cooling conveyor from China manufacturer's screw shaft 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.
