[0002] Screw conveyor, also known as spiral conveyor, is a machine that uses a motor to drive the spiral rotation and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Screw conveyors are divided into two types in terms of conveying form: shaft screw conveyors and shaftless screw conveyors. In terms of appearance, they are divided into U-type screw conveyors and tubular screw conveyors. Shaft screw conveyors are suitable for non-sticky dry powder materials and small particle materials, while shaftless screw conveyors are suitable for conveyors with sticky and easily entangled materials.
