What is a Sieve Analysis? - Definition from

2017-5-17  A sieve analysis is an analytical technique used to determine the particle size distribution of a granular material with macroscopic granular sizes. The sieve analysis technique involves several layers of sieves with different grades of sieve opening sizes.. The finest sized sieve lies on the bottom of the stack with each layered sieve stacked above in order of increasing sieve size.

Sieve analysis presents particle size information in the form of an S – curve of cumulative mass retained on each sieve versus the sieve mesh size. The most commonly used metrics when describing particle size distributions are D-Values (D10, D50 D90) which are the intercepts for 10%, 50% and 90% of the cumulative mass.
