the overall design concept of flexible screw conveyors is relatively straightforward. however, the simplicity of their design can be somewhat deceiving. much like a pneumatic conveying system, the efficiency of flexible screw conveyors is highly dependent on initial design, specialized knowledge of material characteristics, and proper calculation of conveyor flow to preserve the life of the auger.
a screw conveyor can be used for heating and cooling products by utilizing jacketed housings and/or hollow flight screws. screw conveyors can be made out of a variety of materials to make them corrosion resistant, abrasion resistant or heat resistant depending upon the product being conveyed. they can be outfitted with multiple discharge points offering greater system design flexibility.
