The spiral surface of LS400 U-shaped screw conveyor has two forms: solid spiral (S method) and belt spiral (D method). Flanged connections are used between each spiral shaft, ensuring interchangeability of the connecting shafts and facilitating maintenance.

The LS400 U-shaped screw conveyor has four types of feeding and discharging devices: feeding port, square discharging port, manual pushing discharging port, and rack and pinion discharging port, which are opened and welded on the machine body by the user at the site of use.

The LS400 U-shaped screw conveyor uses a rotating screw to move the conveyed material along a fixed casing for conveying work. The head and tail bearings are moved outside the casing, and the suspension bearings are equipped with dust-proof sealing devices using sliding bearings. The bearing shells are generally made of powder metallurgy, and the conveying slurry uses felt bearing shells. The suspension shaft and screw shaft are connected by sliding blocks.

The LS400 U-shaped screw conveyor is widely used as a conveying equipment in industries such as chemical, building materials, grain and oil, feed, food, metallurgy, mining, plastics, and medicine. It is suitable for horizontal conveying, inclined conveying, vertical conveying, and other forms of granular or powdery materials. The screw conveyor has a simple structure, low manufacturing cost, and strong sealing performance.
