Particle Analysis Techniques Compared :: Microtrac.com

The resolution of sieve analysis is limited by the number of obtainable size fractions. A standard sieve stack consists of a maximum of 8 sieves which means that the particle size distribution is based on only 8 data points. Automation of the procedure is hardly possible which makes it rather time-consuming.

How to Perform a Sieve Analysis

For particle size analysis, the test sieve remains a cost effective and precise measuring instrument for dry non-agglomerated particles. Test sieve analysis is widely used for quality control in many industries worldwide, the test sieve process is a simple and common practice to measure particles size and dry relatively free flowing materials.This here assumes the much important & necessary ...

Standard Operating Procedure

For a particle size distribution, the mass retained in a sieve will have a particle size between that sieve and the next larger one. a. For example, if 100 g was sieved using the char method and the 150 µm sieve contained 5 grams of char after shaking, then 5% of the sample has a particle size between 150 and 180 µm. Clean up . 1.
