  • Device and process for the separation and classification of particles forming granular product
    Patent number: 5871103
    Abstract: The device (10) includes 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. The device is further provided with a motion generator (24) arranged to generate a substantially laminar fluid flow in the guiding channel for conveying particles to the guiding channel. The particles introduced in the guiding channel (16) receive the kinetic energy of the fluid flow, fall in the lower container (17) and are recovered at positions which depend of the mass and the kinetic energy received.
