FIELD: mineral benefication equipment, which may be used for benefication of ores, technogenic crude and other solid materials. ^ SUBSTANCE: hydraulic classifier for separation of ground material in descending flow of carrier liquid includes separation pipe consisting of vertical part and lower part having pulser with controllable pulse parameters, said pulser being provided with back valve for reversing flow of carrier liquid. In lower part of pipe, in front of pulser there is baffle for reflecting carrier liquid back flow. Baffle is made in the form of continuous cylinder. Stop is positioned in front of baffle. Ratio of diameter of baffle to diameter of separation pipe complies with condition: 0.5<d/D<1, where d is diameter of baffle for reflecting back flow of bearing liquid, D is diameter of separation pipe. ^ EFFECT: increased efficiency in separating of heavy fraction from light fraction of materials. ^ 4 cl, 3 dwg, 1 ex |
