What Does Air Jet Sieving Mean?

Air jet sieving, as its name suggests, is a particle size gradation method that uses streams of air to move particles through a sieve mesh. Unlike conventional sieving techniques (vibrational, horizontal or tap sieving), air jet sieving does not rely on a mechanical motion. Instead, air is blown through the sieve, throwing the sample into the air while a vacuum sucks the particles through the mesh. Like other sieving methods, air jet sieving is used to separate or measure particles by their size.


Corrosionpedia Explains Air Jet Sieving

The stream of air blown upwards into the sieve serves to distribute the particles across the sieve and change the orientation of the particles. Additionally, agglomerates are also broken up as the particles impact the sieve cover after being tossed in the air.

Unlike other sieving methods that may utilize several sieves (stacks), air jet sieving uses a single sieve. Another unique characteristic of this sieving method is that the sieve itself is not subject to motion. Rather, low pressure in the sieve’s lower chamber forms a vacuum that pulls the particles through the mesh.
