FLEXIBLE SCREW CONVEYORS Move virtually any bulk material Free-flowing and non-free-flowing materials and blends Flexicon flexible screw conveyors (also known as helix conveyors, screw conveyors, spiral conveyors and auger conveyors) offer efficiency and versatility, conveying bulk materials ranging from large pellets to sub-micron powders—both free-flowing and non-free .Assumption: When designing a shaftless screw for use in various types of equipment i.e. (shaftless screw conveyor, shaftless screw feeder, grit classifier.) the most common assumption is the thickest part of the screw profile, should be the out-side peripheral edge of the screw, (in contact with the liner), because this is where the maximum stress is (commonly used flight profiles 1" 3/4 x .

Industrial Screw Conveyors - Anderson Dahlen

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade (flighting), usually within a gutter or tube, to move liquid or granular materials. Screw converyors are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste .Shaftless Screw Conveyors. Shaftless spiral conveyors eliminate the central shaft and allow a much higher fill rate resulting in lower rpm's, more efficient conveying and consequently less wear. Without a shaft, no intermediate or end bearings are required. The trough liner is the spiral.
