APPARATUS FOR AVERAGING OF ORES QUALITY IN PROCESS OF LUMP BY LUMP RADIOMETRIC SEPARATION Russian patent published in 1997 - IPC

FIELD: mining, processes of ores quality averaging in conditions of acting radiometric dressing of ores. SUBSTANCE: apparatus for averaging of quality of mixed standard and sub-standard ores has system of two engaged with each other separators. First separator is processing sub-standard ores, second separator is processing standard ores. There are two in series connected bunkers for mixing of waste tailings and for dressed products, six blocks of measurements accuracy increasing linked to nuclear-physical detectors. To adjust weight shares of mass of mixed dresses products and waste tailings they use in series connected two bunkers, two ores conveyors, two detectors, two block of measurements accuracy increasing, two microcomputers of separators. To control value of limiting concentration they use two blocks of separation process in series connected with two detectors, two blocks of measurements accuracy increasing and two microcomputers of substandard and standard ores separators. There is additional canal for recirculation of waste tailings portions to input of sub-standard ores separator. EFFECT: improved design. 1 dwg
