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.
