Filling device for supplying processing material to an extruder screw and method for supplying processing material to an extruder screw

摘要

The proposed solution relates in particular to a filling device (B) for feeding processing material, in particular granular processing material, to at least one extruder screw (2), with a funnel (5) which is set up to feed the processing material along a feed direction (Z) to the extruder screw (2) to guide, and- a material reservoir (3) for the gravity-driven feed of the processing material to the funnel (5). The filling device has a feed device (8) via which under the action of the extruder screw (2) against the feed direction (Z ) processing material returned to the funnel (5) can be conveyed again together with processing material supplied from the material reservoir (3) in the direction of the extruder screw (2).
