Laboratory for MPE

 

 

The Mechanical process engineering laboratories are used to train students in the Faculties of Process Engineering and Applied Chemistry in the teaching and research fields of mechanical process engineering, product design of disperse systems, and particle technology and raw material processing. In these laboratories, experiments are carried out in the following subject areas:

  1. Product properties (particle characterization)
    • Single particle characterization
    • Sieve analysis, determination of sieving time, air jet sieving
    • Density: Solid density, bulk density, tamped density
    • Specific surface: gas adsorption, flow-through method (Blaine)
    • Sample preparation: sampling, dispersion
    • Sedimentation analysis
    • Optical particle size analysis
    • Rheological properties of complex fluids
    • Interfacial properties/tensiometry
  2. Process properties
    • Comminution and dispersion
    • Coarse grinding (jaw crusher)
    • Wet grinding/ball mill
    • Sieve classification
    • Flow classification
    • Pneumatic conveying
    • Stirring technology
    • Solid/liquid separation technology: filtration and hydrocyclone
    • Air pollution control: filter testing according to VDI guideline 3926
    • Agglomeration (granulating plate and Eirich mixer)
    • Crystallization from solutions
