FIELD: mining.
SUBSTANCE: process plant for the extraction of fine size (0-1 mm) from an initial material using dry method contains short, wide belt conveyor installed at the angle to the horizon of 30-50° in the transversal cross direction fitted with longitudinal separating strips and having a drive, driving and driven reels. Above the belt conveyor at the angle to the horizon of 10-15° a vibration loading chute is installed for the segregational separation of the material layer by fineness is installed. The longitudinal separating strips are fixed on the surface of the belt conveyor at the mutually equal distance of 150 mm and made from rubber with the height of 2 mm and the width of 20 mm.
EFFECT: improvement of the efficiency of fine size extraction, increase in productivity.
