How Does a GLS Tubular Screw Conveyor Work?
The GLS Tubular Screw Conveyor functions on a simple yet highly efficient principle:
a rotating screw shaft within a tubular casing propels materials along the screw’s axis. The head and tail bearings are placed externally, minimizing internal contamination. The dustproof sealing devices in the hanging bearings prevent material leakage and extend bearing life.
Working Mechanism:
The material enters through an inlet.
The rotating screw, driven by a motorized gearbox, pushes the material along the tube.
The material advances through continuous rotation and gravity distribution.
Output is discharged uniformly from the outlet.
This design minimizes friction, prevents clogging, and ensures smooth, consistent material movement even at steep inclines.
