The screw conveyor is divided into two types: axial screw conveyor and shaftless
screw conveyor, in terms of conveying forms. In terms of appearance, is divided
into U-shaped screw conveyor and tubular screw conveyor. The axial screw
conveyor is suitable for conveying dry powder materials and small particle
materials without adhesion while the shaftless screw conveyor is suitable for
conveying materials with adhesion and easy to entangle.





When the screw shaft rotates, due to the gravity of the material and the friction
,between the material and the wall of the trough, the material only move forward
along the bottom of the conveyor under the push of the blades. This is like a
non-rotating nut moving in translation along a rotating screw The movement of the
material at the intermediate bearing is dependent on the push of the material
moving forward behind it. Therefore, the transportation of the material in the
conveyor completely a sliding motion.



The screw conveyor has the characteristics of simple structure, low cost, reliable
operation, convenient maintenance and management, compact size, small
cross-sectional size small space occupation, ability to achieve sealed conveying,
which is beneficial to conveying materials that are prone to flying, hot, and strongly
odorous, reducing environmental pollution improving the working conditions of port
workers, convenient loading and unloading, ability to convey in reverse, and also
allowing a single conveyor to convey materials in two directions the same time.
