FIELD: mining and metallurgy; dressing of source ore and tailings, operational development of concentrates.
SUBSTANCE: the invention is dealt with the field of dressing of source ore and tailings and operational development of concentrates and man be used in mining and an iron and steel industry. The method provides for ` of granular material on a belt of a conveyer-separator at an angle of no more than 45 ° to horizon with simultaneous reciprocating motion in a vertical plane with a frequency from 0.1 to 25.0 Hz, up to its sheeting into layers equal by density and-or by sizes of granules, separation of the layers from each other and throwing them off from the belt by the separator made in the form of the fixed boards, the height of which is stepwise diminished by a thickness of a thrown off layer, catching them and their removal by the catcher. Water is fed into the divided granular weight. The Installation contains a loading device, a conveyor-separator made in the form of a silently moving belt and a granules layer separator made in the form of vertical plates fixed on the spring-loaded cradle of the conveyor-separator as a prolongation of the launder-shaped boards of the belt, that are stepwise diminishing inn height by thickness of the layer thrown off from the belt, and also a catcher of granules of layers thrown off from the belt. The technical result is improvement of quality of dressing, simplification and price reduction of the production process.
EFFECT: the invention allows to improve quality of the granular rock particles dressing, to simplify production process and to decrease its cost.
