Objectives
The student should be able to determine the basic design parameters for equipment used in milling/grinding/emulsification and particle/fluid droplet separations and to interpret the fluid flow hydrodynamics through particle beds.
Program
Grinding / Crushing and Emulsification:
- Types of Mills
- Grinding energy
- Area/volume relation and shape factor
Study of particle motion inside fluids - drag coefficient and Stokes law. Description and dimensioning of equipment of:
-Gravitational classification;
-Sedimentation;
-Centrifugation;
-Fixed and fluidized particle beds;
-Filtration.
Evaluation Methodology
Continuous assessment: two written tests covering theoretical qand practical questions on the design of the studied equipment. The students that obtain an average mark of the 2 tests equal to or higher than 9.5/20 and at least 5/20 in each test will be exempted from taking the exam and pass the course.
Students eligible for the exam will pass if they reach a mimimum mark of 9.5/20.
