FIELD: ore and minerals dressing. SUBSTANCE: separator has a sloping gutter with an auger. In the bottom part of the gutter there is a vat with a drain threshold. The outlet hole of the feeder is beneath the level of the threshold, and in the upper part there is an unloading device. A branch pipe for supply of water is located between the feeder and the unloading device. The auger part beneath the branch pipe is perforated, and the diameter of the perforation holes decreases as the holes are closer to the auger axle. The perforation is arch-shaped, and the last row of perforation holes is open to the external edge of the auger. EFFECT: higher efficiency. 3 cl, 2 dwg
