Apparatus for the agglomeration of feed material with thermoplastic properties

An apparatus for the agglomeration of feed material with thermoplastic properties, the apparatus comprising:

• a radially symmetrical hollow chamber comprising a perforated die defining a periphery of the hollow chamber and a front wall element and a rear wall element closing off ends of the hollow chamber;
• a material feeding system connected to the hollow chamber;
• an agglomerating vane arranged in the hollow chamber and configured to rotate in a direction of rotation about a longitudinal axis of the hollow chamber;
• the agglomerating vane having a front side in the direction of rotation, wherein the front side, the front and rear wall elements, and the perforated die define at least one revolving plasticizing chamber in the hollow chamber;
• wherein the front wall element has an inner surface facing the hollow chamber and the rear wall element has an inner surface facing the hollow chamber, wherein at least one of the inner surfaces of the front and rear wall elements has profiles running from an inner area of the inner surface to an outer area of the inner surface, wherein the profiles are configured to transport the feed material.
