Screw Conveyor Working Principle. When the screw shaft rotates, the material moves forward along the trough bottom of the conveyor under the push of the screw blade. The reason why the material does not rotate with the blade is that it is subject to its weight and the friction resistance generated by the trough wall. Therefore, the transport of materials in the conveyor is completely a slip ...

 · Advantages of Screw conveyor: Screw conveyors are capable of handling a great variety of bulk materials from sluggish to conveyors can have multiple inlet and discharge points.

How Do Screw Conveyors Work? Screw conveyors use flighting, or helical screw blades that rotate, to transport granular or liquid materials through a trough or tube. This technology is based on the principle of the Archimedes screw, which have been used to transport water and other materials for more than 2,500 years. Today, many industries, from agriculture to food processing, use screw ...
