The invention concerns a device for transporting sticky and/or wet material in horizontal direction comprising a shaftless spiral or screw having an outside diameter and an inside diameter, a stationary trough having a prismatic shape with at least at its underside a cylindrical part with a liner for supporting the outside diameter of the shaftless spiral or screw, and drive means for rotating the shaftless spiral or screw around a stationary straight centerline, the stationary trough having an inlet opening for receiving transportable material and at its underside an outlet opening for discharging transported material. According to the invention the shaftless spiral or screw is provided over its active length between the inlet opening and the outlet opening along the centreline with a pipe which is rotatable in the inside diameter of the shaftless spiral or screw.
Device for transporting at least one of sticky and wet material in horizontal direction comprising a shaftless spiral or screw having an outside diameter and an inside diameter, a stationary trough having an inlet opening for receiving transportable material and at its underside an outlet opening for discharging transported material and drive means for rotating the shaftless spiral or screw around a stationary straight centreline, wherein the shaftless spiral or screw is provided over its active length between the inlet opening and the outlet opening along the centreline with a pipe in the inside diameter of the shaftless spiral or screw, wherein the stationary trough has a prismatic shape with along its length at least at its underside a cylindrical part with a liner that supports the outside diameter of the shaftless spiral or screw, characterized in that the pipe thereby prevents the transported material moving through an opening in the inside diameter of the shaftless spiral or screw.
