FIELD: equipment for classification of loose materials; applicable in mineral concentration, for instance, sands in their size classification. SUBSTANCE: hydraulic vibroshaker has a body accommodating sieves installed for changing their angle of inclination together with the body from 10 to 15 deg. Installed above each sieve are tubes on which water sprayers are located. Liquid jets from sprayers are directed toward flow of sand. Distance between sprayers is reduced towards sieve sides. EFFECT: higher efficiency of sand separation by fractions. 2 dwg, 1 tbl
