Abstract: The invention relates to a kneader mixer comprising at least two shafts (2, 3) that are embodied as hollow shafts, on the surfaces of which kneading bars (4) are disposed on webs (5). The design of the shafts is selected such that the eigenfrequencies of the shafts are provided with a distance of at least 5 percent from the excitation frequencies. At least one of the shafts is preferably penetrated by a tempering medium, the inlet being located at one end and the outlet at the other end of the shaft. Preferably, the inventive kneader mixer further comprises at least one opening above the shafts, said opening being configured as a dome that is closed by means of a displacer (22). At least one opening for removing product is also provided. The cross section of said opening can be adjusted during operation.
