The device (10) comprises a separation vat (11) for separating the particles and comprising a cylindrical guiding channel (16) communicating with a lower container (17) formed with two parallel planar walls (21) separated by a distance smaller than the maximum width of the guiding channel. Said device is further provided with a motion generator (24) arranged to generate a substantially laminar fluid flow in the guiding channel, means (18) for conveying said particles to the guiding channel and means (13) for recovering the sorted particles. The particles introduced in the guiding channel (16) receive the kinetic energy of the fluid flow, fall in the lower container (17) and arrive to the recovery means ( 13) at positions which depend of the mass and the kinetic energy amount received.
