Kneader Mixer Extruder Operation

How does a kneader mixer extruder work ?

The kneader mixer extruder consists set of contra-rotating kneading blades, such as the sigma blade or the masticator blade, in combination with either one or two extrusion screws.

The kneader mixer extruder operation is in two modes – mixing mode, discharge mode. In the mixing mode, the blades rotate towards each other; the rotation of the screw ensures a constant feed of material into the mixing zone. During the discharge mode (after completion of mixing), the direction of rotation of the screw is reversed, so that the material is extruded, discharged from the mixing vessel.
