  • Particle size analysis by sieving

    Sieving consists of placing a powder sample onto a sieve containing openings of a fixed size, and agitating the sieve in such a way that particles that can pass through the openings do so. To speed up the analysis, several sieves are stacked on top of each other, with the sieve containing the coarsest openings on top and a 'catch' pan on the bottom.
