About properties in fluid/particle separation
-Different materials behave differently in fluid/particle separation processes.
-Most relevant properties need to be measured, few are available in literature.
-Take care when communicating material properties with equipment suppliers or customers. There are often no unified definitions of measure between industries.
Particle Size
- In many cases, this is the most important property
- Many instruments for measuring particle size
- Many definitions for relating non-spherical particles to an equivalent sphere size
Methods for Particle Size Measurement
- Microscopic Measurement
- Light Scattering Particle Size analyzer
- Particle Counters
- Sedimentation Particle Size Analyzer
- Sieves
- Cascade Impactor
- Mobility Particle Sizer
