Apparatus for the agglomeration of feed material with thermoplastic properties

摘要

An apparatus for the agglomeration of feed material with thermoplastic properties has a radially symmetrical hollow chamber with a perforated die defining its periphery and a front wall element and a rear wall element closing off ends of the hollow chamber. A material feeding system is connected to the hollow chamber. An agglomerating vane arranged in the hollow chamber rotates in a direction of rotation about a longitudinal axis of the hollow chamber. The agglomerating vane has a front side in the direction of rotation. The front side, the front and rear wall elements, and the perforated die define a revolving plasticizing chamber. The front and rear wall elements have inner surfaces facing the hollow chamber and at least one of the inner surfaces has profiles running from an inner area of the inner surface to an outer area of the inner surface for transporting the feed material.
