Particle size determination by sieving method

In this method Particles ranging from 50 to 1500μm are measured. It is a rough and fast way and can obtain weight distribution of particle size. Sieves of various pore sizes are used for sieve the powder.
The sample of the supposed quantity is kept on the sieve top and tapped. In doing so, large sized particles are retained by a particular sieve number. Thus the particles pass through the holes of sieves on the basis of size and move to different levels. Small size particles are settled on the finest sieve.
