A screw conveyor is a mechanical device used for moving bulk materials from one point to another in a controlled and efficient manner. It consists of a helical screw blade, also known as a flighting, that rotates inside a trough or tube. As the screw turns, it pushes materials such as grains, cement, powders, and other bulk solids forward. Screw conveyors are widely used in industries like agriculture, construction, mining, food processing, and chemical plants. They are compact, simple in design, and can be installed horizontally, vertically, or at an inclined angle. These conveyors are especially suitable for handling semi-solid materials and fine powders. Their enclosed design reduces dust and spillage, making them a clean and safe option for material handling. Additionally, screw conveyors are cost-effective and require relatively low maintenance.
