Abstract

The mixing bar (23.3,23.5) on one of the shafts (5/6) engages with one end in the plane (E) of the support elements (24,25,35) in the other shaft (6/5) where at least one supporting element (24/25,35) forms a recess (26,26.1) in the region of the path of the mixing bar (23.3,23.5). The mixer for mechanical, chemical and/or thermal process has two axially parallel, rotating shaft (5,6) in a housing with inner wall (31). The mixing bars (23-23.6) that are formed in the rotation direction and in the axial direction of the shaft run along the inner wall (31) of the housing and in the direction of the shaft or diagonal to the direction of the shaft (5,6) are located on a support element (22,24,25,34,36). The paths of the bars and the support element partially overlap on both shafts, and on turning the bars engages one of the shafts (5 or 6) between the support elements (22,24,25,34,36) on the other shaft (6 or 5).
