Flexible screw conveyors
A flexible screw conveyor moves and elevates bulk material by rotating a helical-shaped auger inside a casing. It is typically used to elevate powders and granular bulk materials into mixers, packaging machines or storage bins. They are called flexible screws because the
auger portion of the conveyor is a shaftless design and the casing is typically Ultra High Molecular Weight Poly Ethylene (UHMW-PE). The spring-like auger and the UHMW-PE casing allows smaller diameter conveyors to be flexed or bent around fixed objects or to change the position of the discharge head.
