The Kneader Extruder combines the efficiency of a double arm mixer with the convenience of extrusion screws for improved mixing and discharge of heavy viscous materials.
The Kneader Extruder includes a set of contra-rotating kneading blades and one or more extrusion screws. The blades are mounted on a horizontal axis in a W-shaped trough. Below the blades in a separate cavity are the extrusion screws. During the mixing cycle the blades rotate towards each other while the mixing screws rotate in a reverse direction, constantly feeding new materials into the mixing blades. After the mixing/kneading cycle is complete, the screws are reversed and they extrude and transport the mixed materials out of the mix zone.
