Abstract (en)
[origin: EP0865889A1] The industrial-scale machine is used for manufacturing ceramics. It has at least one screw mixer (1,5,6) connected to a unit for degassing the mixed material. The degassing unit (2) has at least one chamber (21) connected to a vacuum pump and cutters (9,10) for fragmenting the material. The degassing unit is connected to a screwed (4,13) extruder (3) conveying the material to a stock and die. The chamber of the degassing unit includes a screw (4,7) organised around an axis common with the axis of the screws (4-6) of the mixer and the screws of the extruder. This axis is made up of a single fully rotating shaft mounted out-of-true from a motor reducer driving the shaft up to the die-carrying limb. The shaft carries an assembly of wear pieces of the installation, mounted so that they can be detached from the shaft.
