| 简介 |
Device for isolating of finely dispersed conductive particles from the mixture with the nonmagnetic materials, containing charging hopper, receiving tank for conductive particles, receiving tank for non-conducting particles, agent for forming the magnetic field, agent feed mixture in zone of magnetic field formation, differs, agent feed mixture in zone of magnetic field formation is made in the form of belt conveyor, drum of which is provided with inserts of permanent magnets and is located in the cavity of the housing, made of material impermeable for sverkhvysoko frequency electromagnetic radiation, besides, at the sections of inlet conveyor belt in the casing and exit from it ones are left as inlet and exhaust slots, the conveyor belt is arranged impermeable for sverkhvysoko frequency electromagnetic radiation, for this purpose it is reinforced with metal grid or perforated metal foil, space of casing communicates with source sverkhvysoko frequency electromagnetic radiation, Besides, in wall of housing has slit, through which comes out tray discharge of tailings, while receiving vessel for conductive particles is located at outlet slot. Besides, device is provided with additional permanent magnets, arranged between working and ordinary section of the conveyor belt, for forming on its surface magnetic field. Use of the claimed device provides possibility of almost complete isolation of (catching more than 90% of particles of free gold dimensionality 0.1 mm and practically complete trapping fractions of up to 0.5 mm) of finely dispersed non-ferrous rare and precious metals and thereby possibility for creating effective dressing equipment for primary enrichment of placer deposits of different nature (natural and technogenic) bezreagentnym method (T. e. ecologically safe on reagents in the surrounding medium). 1 3. u. 2 cl. 1 ill. |
