Abstract: The invention relates to a heatable mixer (1) for composite products based on thermoplastic material(s), having an elongated structure defining a longitudinal processing path between an inlet and an outlet and comprising a heated trough (3) wherein two mutually interpenetrating parallel twin screws (4 and 4) are mounted, forming member(s) for dimensionally reducing, heating and moving the products to be treated which are inserted at the inlet, each screw (4, 4?) comprising a heated and driven support shaft (5) arranged in the travelling direction (DT). Mixer (1) characterised in that the thread (4?) of each screw (4, 4) is an interrupted or discontinuous thread and comprises, over at least a major portion of the length of the relevant screw (4, 4?), a plurality of first blades (6) in the form of flat and smooth plates which are separated from each other axially and radially and all arranged according to a constant.

Abstract: The invention relates to a refiner (1) for treating composite products made from thermoplastic material(s), comprising an enclosure (3) with a cylindrical wall, defining a treatment chamber provided with at least one feed opening (5) for products to be treated and at least one outlet opening (5?) for treated products, and a cylindrical drum (6), mounted so as to be able to move in the cylindrical enclosure (3) and having a diameter smaller than that of the latter, the longitudinal axes of symmetry of the outer enclosure (3) and the inner drum (6) respectively being parallel to each other, the refiner (1) being characterized in that it comprises a means for heating the treatment chamber (4) and in that the drum (6) is mounted in the outer enclosure (3) so that it is able to move in rotation about its longitudinal axis (A2) and so that its longitudinal axis (A2) is able to move along a circular path around the longitudinal axis of said enclosure (3), the two types of possible movements mentioned above being con

Abstract: An installation (1) and method for treating composite products (2) based on thermoplastic material(s) for recycling purposes, the installation at least comprising means (3, 4, 4?, 5, 6) for heating, for reducing size, for crushing and for separating, said means being arranged to form at least one line (1?) for treating and extracting material(s) to be reused, operating as a continuous or intermittent flow, and regulated if necessary.
