FREMGANGSMAATE OG INNRETNING FOR OMDANNING AV ET UTGANGSMATERIALE INNEHOLDENDE MINST TO FORSKJELLIGE TERMOPLASTISKE MATERIALER TIL ET NYTT, HOMOGENT TERMOPLASTISK MATERIALE

摘要

The device comprises a cylindrical chamber (2) fitted with a loading hopper (4) and with a discharging well (5). A rotor (6) fitted with blades (31, 32) is driven in rotation by an electric motor (7) via a clutch (18). The chamber (2) and the bearings (22) of the rotor (6) are surrounded by a protective shroud (26). In the chamber (2), a mixture containing at least two different thermoplastic polymers is subjected to stirring (agitation) by the blades (31, 32) of the rotor (6), and this treatment is stopped after the appearance of a rapid increase in the energy consumed. A homogeneous thermoplastic is thus obtained.
