Particle size determination by Sedimentation Method

If any particle falls in liquid, it gradually settles down, the Bigger particle is settled faster than the smaller particles, this principle is to work in particle size determination. The particles of the same density, they are settled only on the basis of size so large particles settled quickly at the bottom of the sediment than the smaller size particles.

Here is mention some advantages and disadvantages of the sedimentation method in particle size analysis let’s check it.
Advantages of the sedimentation method in Particle Sizing

• It has a low cost for analysis.
• Consistent as entire of a sample is screened.
• Continuous operation without disturbance.
• Results are accurate and reproducible.
•  Relatively broad test range.

Disadvantages of the sedimentation method in Particle Sizing

• Test cycle of sedimentation method is long.
