[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of transportation. It can transport horizontally, inclined or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation. It can also stir the materials during the transportation process. At present, screw conveyors are widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal mining, grain and other industries. They are used for horizontal or inclined transportation of powdered, granular and small block materials, such as coal, ash, slag, cement, grain, etc.
