An auger conveyor is a device whose role is to transport sticky and difficult-to-flow materials.
By construction, they can be with an open trough, closed trough or tubular. The working body is a spiral that can be classic or hollow – which is used for extremely sticky substances. With its rotational movement, the spiral forces the transported material to move in the direction of the spiral axis, in the direction of advancing the coil. As a rule, the drive motor and bearings are located on the outside and have no contact with the transported material. If necessary, openings for aeration and inspection / maintenance are made on the riverbed, if it is a closed riverbed.
