Flexible Conveyors
Flexible conveyors contain a large screw located inside of tubular housing. When the screw is turned by a motor, the material rotates along the thread and is transported down the length of the screw. Flexible conveyors differ from rigid screw conveyors in that both the screw and the tubing are capable of bending to some degree. This added flexibility means that the conveyor system takes up less space.
Flexible conveyors are especially useful in transporting powders and materials composed of small granules. These conveyors are also used to feed plastic pellets to a hopper during the injection molding process. Depending on the application, flexible conveyors may be fitted with a variable rate feeder to control the amount of product distributed at a particular time.
