In a mixing kneader for the mechanical and/or thermal treatment of products, there is a shaft (16) arranged in a housing (1), on which shaft disk segments (21) are provided distributed in the axial direction. In the kneading spaces (24) between the disk segments (21) there are fixed kneading counter- elements (27), which clean the disk segments (21) and shaft (16) and comprise a section (30), running close to the disk segments (21), and an arm (31), running close to the circumferential surface (37) of the shaft (16) . In order that the section and the arm can give way to excessive production encrustations on the shaft, a center line (N) of the section (30) close to the disk segments (21)is to run at an inclination, in the direction of rotation (Z) of the shaft (16),corresponding to a secant through to a tangent with respect to the shaft (16). Something similar also applies to the center line (O) of the arm (31) and to a leg (28) adjoining the section (30) at the other end from the arm (31). This has theeffect that the formation of product bridges is also avoided and the product conveyance and mixing action are improved. In addition, the mechanical stressing of the kneading element and the taking up of torque by the shaft are reduced.
