FIELD: concentration industry. SUBSTANCE: invention is designed for use on objects with difficult-to-concentrate raw materials and at reprocessing of waste to separate free particles of precious metals and other heavy useful components from placer sands, crushed ores, tailings, rough concentrates. Proposed centrifugal vibratory concentrator contains working chamber with entrapping coating on its inner surface set into rotation around vertical axle by drive mechanism, inertia unbalance vibrator and housing installed on support through elastic shock absorbers. It has also charging and discharging device. Vibrator is arranged in plane of gravity center of concentrator and is made in form of rotating carrying member with set of fitted-on weights for adjusting its position relative to axis of vibrator and/or gravity center of concentrator. EFFECT: improved efficiency of concentration at higher reliability in operation. 2 dwg |
