We are working in the entire field of particle technology and solids process engineering and will help you with our experimental and numerical methods to find solutions for your solid challenges. Besides our below mentioned research areas in the R&D field, we also offer consultancy for any kind of problems and challenges in particle technology.
Overview of research areas
Plants Fluidized and spouted beds in lab- and pilot plant-scale, rotor granulator, spray dryer, agglomerator, mill
Processing methods Granulation, agglomeration, coating, drying, milling
Measurement of Particle size and size distribution, flow properties, moisture content, angle of repose, dynamic vapor sorption isotherms, surface morphology, particle and bulk density, coefficient of restitution, particle strength and deformation, contact angle, surface tension, process gas analysis
General Multiscale simulation of solids processes
Sub-micro scale Investigated materials can be described by applying force balances in Discrete Element Method (DEM); non-spherical particles can be investigated by using the Bonded Particle Model (BPM)
Micro-scale Coupling of DEM with Computational Fluid Dynamics (CFD): investigation of particle dynamics in a fluid field considering collision dynamics of single particles
Meso-scale Extension of the CFD-DEM simulations by integration of heat and mass transfer correlations
Macro-scale Prediction of distributed particle properties (e.g. size distribution or moisture content) by multidimensional Population Balance Models (BPM); integration into flowsheet simulations is possible
Scale-up By performing experiments in lab- and pilot plant-scale, the scale-up potential of fluidized and spouted beds is evaluated; in addition, the energy consumption is calculated
Optimization of plant configuration By changing the geometry of the apparatus or by the installation of draft plates or tubes, the flow pattern in gas-solid processes can be changed and the stability increased
Residence time adjustment The product quality in continuously operated gas-solid processes is defined by the residence time distribution of the particles in the apparatus. We offer different measurement methods (e.g. magnetizable tracer particles); the residence time distribution can be changed by internals installed in the process chamber
