A device for separation of granular mixtures in a fluid comprising a hopper with a vibrating tray, a generator mounted underneath, with vertical rigid walls located under each other and at an acute angle to the vertical, which pitch and width of location increases from the top to bottom, connected to a source of pressurized air and covered by side walls, and collectors of fractions, and the end of each rigid wall along its entire length is equipped with an additional wall, which width is less than the distance between the adjacent upper rigid wall, which is located with an offset horizontally to form a gap relative to the lower rigid wall, and chambers for turning the air flow at inlet to the gap, while the chambers for turning and gaps are increasing from the top to bottom. |
