SCREENING ON A SCREEN WITH A VIBRATING SIEVE

Screening on screens with vibrating sieves is carried out with thin material layers. The thickness of material layer on the sieve is as small as possible. It would be ideal if the layer thickness could be equal to the dimension of the particle classified. However, in practice it is assumed that this thickness can reach several diameters of the classified particles.
