Shaftless Helical Screw Assembly

Product Overview

Jiahe Conveying's Shaftless Helical Screw Assembly is an innovative bulk material handling solution designed for challenging conveying applications. This advanced design eliminates the central shaft to provide superior flow characteristics and reduced maintenance when handling sticky, viscous or fibrous materials that tend to wrap around traditional screw conveyors.
