Screw conveyors are mostly used to move liquid or particulate materials usually within a tube, Especially, A screw conveyor is a mechanism which uses a rolled out helical screw blade also called as flights. Infrequently, a screw conveyor is also called as helical conveyor or auger conveyor. They are made in this way so that they help in the easy flow of the material, generally semi-solid material like animal feed, wood chips, boiler ash, municipal solid waste, food waste and many others through it in horizontal as well as vertical direction. But the inclined conveyors are more useful and transports the material more effectively. The first screw conveyor was used to pump irrigation water.
Materials which have flow ability are transported through the screw conveyors and normally sticky and stingy material are avoided to be conveyed through screw conveyors. Also, due to high friction of the materials against the screw and trough leads to higher power consumption, there are some chances of material degradation. Therefore screw conveyors have some limitations in the capacity and distance of conveying of the material. Despite this disability of the screw conveyor, they are rather widely used in large as well as small engineering works .
