Karlsruhe Institute of Technology (KIT) Institute of Mechanical Process Engineering and Mechanics Group: Process Machines

The research group Process Machines at the Institute of Mechanical Process Engineering and Mechanics (MVM) deals with processes of particle generation and particle processing in liquid phase. The focus of the work is on filtration and centrifugation as well as mixing technology or agglomeration. Extensive experience is available in all areas due to the fact that MVM has already been in existence for more than 50 years. In addition to the characterization of dispersity properties, modeling and simulation of multiphase flows on the micro and macro scale, the development of digital twins and battery simulation a further research focus. Additionally, the direct recycling of battery materials has also been a new focus of research at MVM for several years.

Within the competence cluster greenBatt, KIT-MVM is involved in the subproject HydroLIBRec. The main task of KIT-MVM within the project is the experimental investigation and implementation of direct recycling by means of continuous fractionation of black mass in decanter centrifuges.  Furthermore, based on the gained knowledge during experimental investigation, the development of a digital twin for the description of the continuous fractionation in decanter centrifuges is another focus of this subproject. At the end, a continuous process will be available that allows the fractionation of active materials while maintaining a high degree of purity.
