Double shaft screw conveyor
Key words:
LLS double shaft screw conveyor
The double shaft screw conveyor is a highly efficient conveying device designed specifically for sticky, lumpy, or fibrous bulk materials. Its core feature is the two parallel, counter-rotating screw shafts, which are widely used in industries such as chemical, environmental protection, and food processing. It is suitable for special materials like sludge, distiller's grains, compound fertilizers, and biomass.The structure of the double shaft screw conveyor consists of a drive unit, double screw shafts (equipped with intermeshing blades), a fully enclosed casing, and inlets and outlets. When the double shafts rotate in opposite directions, the blades intermesh and shear, not only pushing the material along the axial direction but also breaking up lumps and mixing the components. This design solves the common problem of blockages in single-shaft conveyors.Compared to single-shaft models, the double shaft screw conveyor offers stronger resistance to blockages, more uniform conveying, and integrated mixing capabilities. The fully enclosed design prevents the leakage of odors and dust, making it suitable for horizontal or slightly inclined conveying applications. The robust shaft system and wear-resistant blade design ensure stable operation under harsh working conditions, making it an ideal choice for 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.
