CENTRIFUGAL CONCENTRATOR (MODIFICATIONS) Russian patent published in 2000 - IPC

FIELD: separation of mineral particles according to the density of a wide range of grain size and fractional composition of concentrated ores, placers, and cleaning of liquid materials, petroleum products of impurities from 5 μm and higher at high indices of their concentration in disintegration products /10⁴-10⁵/. SUBSTANCE: the concentrator rotor consists of several equilibrated sectors, each provided with interchangeable concentration chambers of various constructions conformably to separation of highly thin materials (0 to 2 mm), consisting of a body of two or more cascade-arranged shelves with taper surfaces with perpendicular bars, shutoff devices and guides for disintegration of material into disintegration products and their recleaning, and vibrators. The chambers for disintegration of granular materials (0-5 mm) in pulsating liquid represent movable cylinders provided with taper perforated diaphragms with tabs-valves, drain chutes and drives for production of pulsating liquid consisting of rockers, levers, section for engagement with a roller. The chambers for cleaning of liquid materials of impurities are provided with cylinders, having drain chutes and taper bottoms with pipe connections for discharge of sediment, and valves. The rotor has the shape of a horizontal wheel with hollow spokes, the feed proportioner is secured in the centre of the rotor. EFFECT: enhanced efficiency of material disintegration according to the density without limitation of the fractional and granulometric composition. 4 cl, 12 dwg
