Ho na le mekhoa e mengata eo liminerale li ka sebetsoang ka eona. E 'ngoe ea litsela tsena ke ka mokhoa oa ho arohana ha electrostatic. Mokhoa ona o lumella li-mineral processors ho arola liminerale tsa boleng bo holimo le ho li arola ho liminerale tse ling tsa gangue. Joale karohano ea electrostatic ke eng le hore na e sebetsa joang? Sehloohong sena, ST Helmets & Technology LLC (STET), explains the key features of electrostatic separation and how we incorporate it into our karohano thepa thekenoloji.
Karohano ea electrostatic e arola liminerale ho ipapisitsoe le likarolo tsa tsona tse mpe kapa tse ntle. Karohano ea electrostatic e sebelisoa ka mekhoa e mengata, empa hangata e sebelisoa indastering ea ho lokisa liminerale. Mohato oa bohlokoa oa ho lokisa liminerale ke ho arola liminerale tsa bohlokoa ho tsoa ho likarolo tseo e seng tsa bohlokoa (gangue). Mohato ona o lumella tlhahiso ea liminerale tsa boleng bo holimo tse hlokahalang ho theheng lihlahisoa tse fapaneng.
Ho na le mekhoa e 'maloa e fapaneng thepa ea karohano ea liminerale e sebelisa karohano ea electrostatic. Boemong bo bong le bo bong, sepheo sa mochine ke ho arola likaroloana tse fapaneng tse qosoang ho tse ling. Sena se phethoa ka poleiti e bapileng, letlapa la angular, kapa se arolang meropa. Ho e 'ngoe le e 'ngoe, ho na le likarolo tse tharo tse kholo - ho tjhaja ha likaroloana, phetiso ea likaroloana tsena, le ho arohana ha likaroloana. E 'ngoe le e' ngoe ea mehato ena e hlokahala ho hlahisa sehlahisoa sa boleng bo holimo.
Nakong ea mokhahlelo oa tefiso ea likaroloana, liminerale li fumana litefiso tse fapaneng tsa motlakase. Mokhahlelong oa phetiso, likaroloana tsena tse qosoang li khahloa ke poleiti e nang le tefiso e hanyetsanang (lipoleiti tse ntle li hohela likaroloana tse mpe le ka tsela e fapaneng) le ho fetisetsoa libakeng tse fapaneng. Mme qetellong, mokgahlelong wa karohano, li arotsoe ka likarolo tse peli tse fapaneng ho latela litefello tsa motlakase.
Hobane ho na le mefuta e fapaneng ea lisebelisoa tsa karohano ea liminerale tsa electrostatic, e mong le e mong o sebelisa mekhoa e ikhethang bakeng sa ho arola boitsebiso. Bakeng sa sehlooho sena, re tla feta ho e 'ngoe le e' ngoe ea mekhahlelo ena re sebelisa mohlala oa triboelectric Sekhetho sa STET.
E 'ngoe ea likarolo tsa bohlokoa tsa karohano ea electrostatic ke ho tjhaja likaroloana. E le ho arola likaroloana, di tlameha ho tjhajwa motlakase pele. Ho tjhaja likaroloana ho ka etsahala ka mekhoa e mengata, empa karohano STET sebelisa ho tjhaja triboelectric. Ho etsa sena, liminerale li feptjoa ka karohano 'me li oela ka lekhalo la li-electrode (sebaka se pakeng tsa poleiti e tjhajoang hantle le poleiti e tjhaetsoeng hampe). Lekhalo lena ke moo likaroloana li thulang tse ling ebe lia tjhaja. Likaroloana tse ling li tla ba negative 'me tse ling li tla ba positive charges.
Ka mor'a hore likaroloana li qosoe, ebe baa arohana. Hobane likaroloana tsena li na le qoso e mpe kapa e ntle, li huleloa lipoleiting tse nang le litekanyo tse fapaneng. Likaroloana tse ntle li khahloa ke poleiti e mpe. Ka mokhoa o ts'oanang, likaroloana tse qosoang hampe li hoheloa ke poleiti e ntle. Between the plates and the particles is an open-mesh belt that conveys the particles in opposite directions. Likarolo tse nang le litekanyo tse ntle li hoheloa holimo 'me li tsamaisoa ke lebanta ho ea ka ho le letona. Ka papiso, likaroloana tse qosoang hampe li hoheloa ka tlase 'me li tsamaisoa ke lebanta ka ho le letšehali.
Ka mekhoa e meraro ea bohlokoa ea karohano ea triboelectric, li-mineral processors li ka hlahisa liminerale tsa boleng bo holimo tse ka sebelisoang ho theheng lihlahisoa tse fapaneng. ST Helmets & Technology LLC (STET) ho na le melemo feela ea ho sebelisa karohano ea electrostatic holim'a carbon-dense fofa molora, MA.
