Spiral conveyor with shaft

Spiral conveyor is a kind of machinery that uses motor to drive screw rotation and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and closed transportation. Spiral conveyor can be divided into shaft screw conveyor and shaftless screw conveyor in conveying form, and U-type screw conveyor and tubular screw conveyor in appearance. The shaft screw conveyor is suitable for cohesionless dry powder materials and small particle materials (such as cement, fly ash, lime, grain, etc.), while the shaftless screw conveyor is suitable for viscous and easy winding materials.
