    Abstract: A method for mixing flowable polymer material with particulate additive utilizes a continuous process. A pre-blend of the polymeric material and additive is made in a hopper. The pre-blend is compacted and fed into a first mixing arrangement to form an intermediate blend. The first mixing arrangement has a rotor with a helical flight located within a chamber. The intermediate blend is fed into a second mixing arrangement to form a final blend. The second mixing arrangement has a conical rotor with blades. The rotors of the first and second mixing arrangements are coaxial but operate at different speeds.
