Michaela Lindemann, M. Sc.Modelling of industrial separation processes
• models of mechanical treatment processes• mass flow model enables economic
evaluation• conclusions drawn from single-particle
information• use of non-spherical particles
→ facilitate a shift from experience toscientifically based process design

The End
d
Michaela Lindemann, M. Sc.Modelling of industrial separation processes
scenario: unit settings set for lowest effortaim: ensure minimum quality of products
incident: change of input composition
result: decrease in process efficiency no access to markets!
