摘要: There is provided a multi-screw extruder for reclaiming foam made of cross-linked polymer material into reusable material by causing the foam to pass through a kneading zone, wherein the kneading zone is divided into at least preceding and subsequent two kneading zones and a temperature equalizing transfer zone for equalizing temperature of the material passing through the zone is provided between the preceding kneading zone and the subsequent kneading zone.
