Screw Conveyors

A Screw Conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a flighting, usually within a tube, to move liquid or granular materials. They 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, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others. 

Most screw conveyors contain the following components:

•A conveyor screw, also known as a spiral blade or helicoid flighting

•A screw conveyor trough or tubular casing

•A drive unit (a shaft coupling and shaft seal or a chain drive)

•The drive mechanism

The conveyor screw (a spiral blade coiled around a shaft) is housed inside the tubular casing, where it is driven at one end and held at the other. The trough may or may not feature a trough cover. Sometimes, screw conveyors feature a spiral blade, but no shaft. In this case, they are called shaft less screw conveyors, and the blade is driven at one end and free at the other.
