CENTRIFUGAL-VIBRATING SEPARATOR Russian patent published in 1996 - IPC

FIELD: mineral resources benefication, production of apparatuses for separation of noble metals and other weighty useful component out of sands and concentrates. SUBSTANCE: separator has conical bowl 1, on inner surface of which there is system of ring-type riffles 2 used for trapping and holding heavy useful components, with two enlarged in height rifles 3 and 4. Bowl 1 using conical transmission with vibration exciter 6 is brought into rotation by electric motor 5. Riffle 3, that is protruding behind cone generatrix by value, that by 1.1 - 1.25 times exceeds height of the rest riffles 2 and is located first from bowl bottom, significantly increases loosening of compacted grain mass and facilitates extraction of middle and big classes of рnoble metals. Riffle 4, that is protruding behind cone generatrix by value, that exceeds by 1.35 - 1.45 times height of the rest rifles and that is located at space of 0.52 - 0.62 from bowl bottom. is locally loosening grain mass and facilitates extraction of small and fine classes. EFFECT: increased extraction of noble metals and other heavy useful components from sands and concentrates. 1 dwg
