Abstract
A mixing and reducing machine with an upward-conveying mixing spiral that rotates around a vertical rotational axle. In order to achieve a more intensive mixing of the mixed product a second mixing spiral is connected in the axial direction after a first mixing spiral, with a transition zone arranged in between. In this way, zones of different axial conveying capacity are connected after each other in the axial direction. The mixing spirals are formed of several mixing blades arranged after each other in the circumferential direction.
