A multi-stage vacuum kneading-extruder includes a degassing chamber (3) for storing material to be processed and reducing pressure of space for storing the material, a kneading-conveyer device (4) for kneading while conveying the material sent from the degassing chamber (3), and an extruding mechanism (5) for extruding the kneaded material, at a conveyer terminal end of the kneading-conveyer device (4), into a predetermined shape. The kneading-conveyer includes a pair of conveyer screws (17,18) disposed one after another in a conveying direction of the material and a grinding-kneading mechanism (16) interposed between the front (17) and rear (18) screws. The grinding-kneading mechanism (16) includes a plurality of unit kneading mechanisms disposed in opposition to each other relative to the material conveying direction. Each of the unit kneading mechanisms (16) includes an un-rotatable stationary disc, a rotary disc rotatable relative to the stationary disc and a stationary filter interposed between the stationary and rotary discs. <IMAGE> |
