Selective Particle Fractionation in Multi-Parameter Potential Fields / Multi-Field Fractionation (M-FF)

Development of separation methods and processes for the fractionation of highly specific fine particle systems (< 10 μm) with multidimensional property distributions in industrially relevant mass flows.

In the Priority Programme 2045 funded by the German Research Foundation (DFG), 24 sub-projects are being carried out with the aim of further developing existing particle technology processes and identifying and implementing new approaches in order to solve the separation tasks of the present and, above all, of the future.

In line with the development of demand in the processing industry, the requirements for primary and secondary raw materials are becoming continuously higher. Increasingly purer, finer and more specific particle systems must be provided in order to guarantee the required quality of the end product. Since many of the established separation processes in the field of finest particles (< 10 μm) are losing much of their specificity, alternative approaches must be developed. This is done in the subprojects located throughout Germany under the coordination of the Institute of Mechanical Process Engineering of the Technische Universität Bergakademie Freiberg.

Due to excellent approaches to solve the presented problem, the Universität Bremen could contribute 3 subprojects.

The Particle and Process Engineering group of the Universität Bremen and the Leibniz-Institute for Materials Engineering IWT are conveying the project B4: "Selective Particle Fractionation in Multi-Parameter Potential Fields / Multi-Field Fractionation (M-FF)". In this project, particles from an aerosol are separated into fractions by means of superposition of acoustically resonant and electric fields, depending on the material parameters of the specific particles.
