A screw conveyor is a mechanical device used to move bulk materials from one place to another. It consists of a rotating helical screw, or auger, that pushes materials along a trough or tube. This type of conveyor is commonly used in industries such as agriculture, food processing, and construction for transporting grains, powders, and other loose materials. Screw conveyors are efficient and can handle a variety of materials, including those that are wet, dry, or granular. They can be designed for horizontal, inclined, or vertical movement, making them versatile for different applications. Their simple design allows for easy maintenance and operation.
