All About Screw Conveyors (Auger Conveyors)
· The shaftless screw conveyor (also known as a ribbon screw conveyor) is an improvement to the typical screw design, as it allows material to flow "through" the auger as well as around it. This may seem like a small change, but it makes a huge difference in practice as it increases the efficiency, flexibility, complexity, and range of conveyable products.
