The Annular Gap Expander consists of a thick-walled mixing tube with replaceable liners and a cantilevered shaft which is fitted with proportioning, mixing and kneading elements.

The hydraulically adjustable cone at the outlet together with the outlet ring form the patented annular gap. By means of adjusting the cone, the pressure, the intensity of kneading, the product heating, and the energy consumption can be controlled and programmed continuously and instantaneously.
