Planung, Konstruktion und Betrieb einer Zentrifugalkraftscheideranlage für die Dichtesortierung von Feinkunststoffen

It is the scope of this thesis to create a fully functional centrifugal force field separator plant, similar to the pilot plant of the Circulyzer GmbH but at a practical lab scale. Its ground plan should not exceed the area of two euro-pallets. The reason for downscaling lies not only within the saving of space but should also enable the separation of very fine particles. Furthermore, it should be noted that the small size of the plant should reduce the amount of material lost during the separation process. The planning and realization of this project is conducted within the realm of the concept known as Rapid Prototyping, as it heavily relies on additive manufacturing techniques. As far as it was feasible in regard to finances and safety, the parts and machines required for the plant were manufactured independently. Concluding trials proof not only, that the constructed plant fulfils the requirements but also that the separation of polymer wastes in a force field separator is a readily scalable process which is also capable of separating very fine polymer waste fractions. Furthermore, new insights into some of the fluid mechanical processes withing the force field separator are gained.
