Abstract: A compounding system for feed material containing plastic waste comprises a chamber assembly, a shaft, a sleeve, and a plurality of arms. The chamber assembly defines a working chamber. The sleeve is supported on the shaft for movement between an operating position and a maintenance position. The sleeve is located within the chamber assembly when the shaft supports the sleeve in the operating position and is located outside of the chamber assembly when the shaft supports the sleeve in the maintenance position. The plurality of arms is supported by the sleeve such that the arms radially extend from the sleeve. Feed material is processed with the sleeve in the operating position. The sleeve and arms may be accessed with the sleeve in the maintenance position.

Abstract: The present invention may be embodied as a compounding system having a chamber assembly defining a working chamber; a shaft, a sleeve assembly, and a plurality of arms. The sleeve assembly has first and second sleeve members each defining at least one arm opening and adapted to be arranged in a first configuration in which the first and second sleeve members are detached from each other and a second configuration in which the first and second sleeve members are secured together around the shaft to support the sleeve assembly on the shaft. Each of the arms is configured to be inserted partly through one of the arm openings when the sleeve assembly is in the first configuration and held in a desired configuration relative to one of the first and second sleeve members when the sleeve assembly is in the second configuration.
