ABSTRACT:
The screw or worm mixer comprises a downwardly tapering container and a conveying and mixing screw or worm arranged therein which does not move along the container wall. The container does not have a round cross-section but a substantially cornered cross-section and the screw is arranged in one corner thereof. This corner is rounded to form a curvature which is essentially concentrically arranged relative to the lengthwise axis of the screw. The entire container is pivotably supported so that, depending upon the requirements of the processed material, the container wall which is adjacent to the screw or worm and forms a segment of a cylinder is located somewhat below, adjacent or above the screw. Due to such arrangement no relative movement between the screw and the container is necessary, which not only simplifies the construction but also enables further stirring or agitator units to be mounted at the container wall, thereby permitting a number of mixing operations to be performed in succession in the same mixer.
