In many facilities, tight spaces and fixed obstacles are the reality on the production floor. In such environments, routing conveyors around existing equipment and obstacles can be a real challenge. The solution – angled conveying with flexible screw conveyors.
Flexible screw conveyors are just what their name suggests – flexible! With a bendable plastic tube, these conveyors can be routed around equipment and other obstacles in process areas. Their flexibility and versatility, as well as relative low cost, makes flexible screw conveyors an ideal choice for conveying many bulk solid materials, including free- and non-free-flowing materials and blends.
Flexible screw conveyors derive their flexibility from two sources: the UHMWPE semi-rigid plastic tube, and the steel auger (or spiral) that make up the heart of the conveyor. The food-grade plastic tube can be curved, or angled, to circumvent equipment and obstacles, while the steel auger which rotates within the tube, is sufficiently flexible to accommodate to most changes in the tube curvature.
The degree of angled conveying that can be achieved with a flexible screw conveyor is largely a function of conveying distance – as the conveying distance increases, the conveyor tube lengthens and is capable of supporting a greater radius of curvature or bend. For UniFlex flexible screw conveyors from UniTrak, we recommend a minimum radius of 10 degrees. In addition, the tube can only have a single radius, and it is not possible to create multiple bends with the same tube.
Flexible screw conveyors are a versatile equipment type that can move a variety of bulk solid materials. Key advantages of these conveyors are the following:
Some limitations of flexible screw conveyors are the following:
UniTrak manufactures the UniFlex line of flexible screw conveyors. Available in two sizes (H75 and H125), these conveyors will move materials over various distances and angles.
