How Does an LS Screw Conveyor Work?
The working mechanism of the LS Screw Conveyor follows a simple yet highly effective principle:
Material Feeding: Bulk materials are introduced through a controlled inlet via gravity or a hopper.
Conveying Action: The rotating screw blades (20–120 RPM) move materials along the enclosed U-trough or tubular casing.
Friction and Weight: The weight and casing friction prevent bulk materials from rotating with the auger blades, ensuring continuous forward movement.
Discharge: Material exits through a designated outlet for further processing or packaging.
Dust Control: The enclosed design ensures zero spillage and dust emission, maintaining workplace cleanliness.

Low noise operation (≤78 dB).
Modular structure for easy maintenance and installation.
Excellent sealing—ideal for cement conveyor applications.
High-efficiency drive system (up to 98%).
