Description
В описываемом изобретении предлагаетс производить обогащение полезных ископаемых в среде мелкоразмолотого минерала или другого материала с размером частиц от 0,15 до 0,3 мм при продувке ее струей воздуха, в так называемом «кип щем слое.The described invention proposes to enrich minerals in a medium of finely ground mineral or other material with a particle size of from 0.15 to 0.3 mm when purging it with a stream of air in the so-called "fluidized bed."
Регулировка удельного веса среды производитс с помощью добавлени к ней зерен обогащаемой руды или угл и породы.The specific gravity of the medium is adjusted by adding grains of enriched ore or coal and rock to it.
Регенераци суспензии, засоренной в процессе обогащени , осуществл етс путем частичного ее отвода дл предварительного отсеивани на грохоте и окончательной очистки на воздушном классификаторе , также использующем принцип предлагаемого способа обогащени .Regeneration of the suspension that is clogged during the enrichment process is carried out by partially withdrawing it for preliminary screening at the screen and final cleaning at an air classifier, also using the principle of the proposed enrichment method.
Дл проведени технологического процесса обогащени рекомендуетс обычный сепаратор, представл ющий из себ ванну с пр моугольным пористым дном, через которое нагнетаетс воздух.For the enrichment process, a conventional separator, consisting of a rectangular porous bottom bath through which air is injected, is recommended.
Дл транспортировки осевщей во врем процесса обогащени т желой фракции угл или руды предназначен конвейер, звень которого имеют сетчатое дно.To transport the heavy fraction of coal or ore that has settled during the enrichment process, a conveyor is designed, the links of which have a mesh bottom.
Удаление всплывщей на поверхность кип щего сло легкой фракции производитс вторым конвейером скребкового типа.The light fraction removed on the surface of the fluidized bed is removed by a second scraper conveyor.
Передвижение сетчатого конвейера осуществл етс синхронно от двух приводных звездочек.The movement of the mesh conveyor is carried out synchronously from two drive sprockets.
Посто нный удельный вес раздел ющей среды поддерживаетс автоматически- При этом используетс пр ма пропорциональна зависимость между удельным весом среды и давлением нагнетаемого воздуха. В качестве исполнительного органа схемы автоматики предлагаетс кольцевой дифманометр.The constant specific gravity of the separating medium is maintained automatically. In this case, a direct proportional relationship between the specific gravity of the medium and the pressure of the forced air is used. An annular differential pressure meter is proposed as the executive body of the automation circuit.
Таким образом, в изобретении предлагаетс осуществл ть процесс обогащени полезных ископаемых в воздушных суспензи х с помощью сепараторов такого типа, которые обычно примен ютс при обогащении в водных суспензи х. Благодар такому сочетанию ранее известных способа и аппаратуры, впервые достигаетс практическа возможность эффективно осуществл тьThus, the invention proposes a process of mineral processing in air suspensions using separators of this type, which are usually used for enrichment in aqueous suspensions. Thanks to this combination of the previously known method and apparatus, for the first time it is practically possible to effectively
