Mobile screw conveyor is a type of conveyor. It is widely used in the transportation of bulk materials in feed, chemical, food processing, and grain processing, grain storage, various additives, construction engineering and other industries.

Working principle

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 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. 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.

The mobile screw conveyor provides the screw conveyor with the ability to move at will by installing the universal wheel, which is especially suitable for the operation of unfixed position such as bulk material loading.
