Shaftless screw conveyor
Key words:
The shaftless screw conveyor is a special bulk material conveying device that eliminates the traditional central shaft.Its core components include the shaftless screw blade,wear-resistant liner,drive unit,and fully enclosed casing.It is widely used in environmental protection,municipal,and food industries,and is suitable for materials that are prone to entanglement and blockage,such as sludge,food waste,fruit and vegetable residues,and sticky powders. The shaftless design fundamentally solves the common problems of material jamming in the gap between the shaft and blade,and fiber entanglement in traditional shafted conveyors.The screw blade is directly driven by the drive unit to rotate,and the material is pushed forward along the inner wall of the liner,significantly improving the smoothness of conveying. The fully enclosed casing prevents the leakage of odors and dust.The liner is made of wear-resistant materials to extend the service life of the equipment.The compact structure and flexible turning capability of the device make it adaptable to narrow spaces and multi-angle layout requirements.Although the conveying distance is relatively short,its strong resistance to blockage and ease of cleaning make it an ideal alternative to traditional shafted conveyors when handling materials with complex characteristics.
Precautions for Installation of Screw Conveyors
When installing a screw conveyor, pay close attention to the following core aspects to ensure stable operation and long service life:
Overflow Screw Conveyor: Characteristics, Core Advantages and Applications
The core characteristic of the overflow screw conveyor is its open-top trough design. Unlike closed screw conveyors, when the feed rate exceeds the rated capacity, excess materials can naturally “overflow” and be discharged without shutting down the machine. Meanwhile, it is suitable for handling complex materials such as high-humidity and viscous substances. It features a compact structure and easy observability.
