FIELD: process engineering. ^ SUBSTANCE: invention relates to mining, particularly, to assembly units of equipment for separation of solids in concentration of minerals. Proposed deck comprises plate with compressed air feed bores and guide grooves. Deck is equipped with rods arranged on said plate in the zone of said grooves perpendicular to plate working surface. Distance between rods is selected to make, at least, the size of larger lump of rock being separated. Rods are arranged in, at least, one line. Every line is directed along deck reciprocation. Said rods are arranged along straight line, or at peaks of zigzag line. ^ EFFECT: higher accuracy of sizing loose material to density. ^ 5 cl, 1 dwg |
