The working principle of the screw conveyor is achieved by the rotating spiral blades pushing the material forward.  The force that prevents the material from rotating with the screw conveyor blades is the weight of the material itself and the frictional resistance between the material and the casing of the screw conveyor.

YHDE screw conveyors can transport materials horizontally, inclined, or vertically, and can also be customized in different sizes and shapes according to requirements.  They have the advantages of simple design, compact structure, small cross-sectional area, good sealing performance, easy operation, easy maintenance, and convenient closed transportation, occupying less space and with low maintenance costs, which can save costs for enterprises.
