| Abstract | The EU's circular economy concept necessitates the recycling of material streams used once or multiple times into the production-consumption cycle again and again. The commonly known problem - that the number of recycling cycles of plastics is limited - drives the economy towards metal usage again, because metal recycling cycles are limitless. Therefore, the efficient and economic separation of mixed aluminium and copper scraps in the 30-100 mm particle size range is an important issue for our society. In this study fundamental and applied research was carried out for the application of a gas-solid fluidised bed separator for aluminium-copper scrap recycling. A laboratory scale aero-suspension dense media separator was developed. Fundamental fluidisation experiments were carried out with this device and a powder rheometer. Afterwards pilot-scale and later industrial-scale separators were designed and built. The results indicate that the well-known Ergun fluidisation model can be the basis of a new process engineering design method for sizing dry fluidised bed separators. |
