ST Izinsiza kusebenza & Ubuchwepheshe LLC sika (STET) Triboelectrostatic ibhande isihlukanisi (Figure 1) inamandla wabonisa ukucubungula izinhlayiya emihle kusukela 1995 uhlukanisa carbon Unburned kusukela impukane umlotha namaminerali izitshalo zikagesi ezisebenza ngamalahle wadubula e eNyakatho neMelika, I-Europe kanye ne-Asia ukukhiqiza i-Pozzolan yebanga likakhonkolo ezosetshenziswa esikhundleni sikasimende. 1 Ngokusebenzisa wendiza ukuhlolwa isitshalo, e-isitshalo ukuboniswa amaphrojekthi kanye / noma imisebenzi kwezohwebo, isihlukanisi STET sika uye wabonisa Ukuzuzisa amaminerali amaningi kuhlanganise potash, barite, calcite, futhi talc.2

Njengoba isithakazelo eyinhloko kule ubuchwepheshe kuye kwaba yikhono layo ukucubungula izinhlayiya esingaphansi 0.1 mm, umkhawulo ezivamile ukuwa futhi sigubhu roll separators, umkhawulo kasayizi wezinhlayiyana ophezulu womklamo wamanje we-STET awuzange ube umgomo wokuthuthukiswa kobuchwepheshe esikhathini esidlule.. Nokho, iyaqhubeka imizamo yokuyikhulisa ngezinguquko zedizayini. STET okwamanje silwenza osayizi ezimbili namandla ngokulinganisa of 40 futhi 23 tonne imethrikhi ngehora.

Izimiso okusebenzela kuyo isihlukanisi STET zikhonjiswe e Izinombolo 2 & 3. I izinhlayiya icala by umphumela triboelectric ngokusebenzisa kuyizinhlayiyana-to-kuyizinhlayiyana ukushayisana emoyeni slide okuphakelayo distributor futhi ngaphakathi igebe phakathi electrode. Voltage isicelo kwi electrode esiphakathi ± 4 futhi ± 10kV isihlobo emhlabathini, enikeza Imininingwane voltage umehluko 8 ukuze 20 kV. ibhande, eyenziwe ngepulasitiki-non-kokuqhuba, kuyinto anezikhala enkulu nge mayelana 60% endaweni evulekile. I izinhlayiya izophela kalula ngokusebenzisa ukuvuleka e ibhande.

Amaphethini okugeleza kanye nokuxhumana kwezinhlayiyana kuya kwezinhlayiyana ngaphakathi kwegebe le-electrode elisungulwe ibhande elihambayo liyisihluthulelo ekusebenzeni kwesihlukanisi.. Lapho engena igebe phakathi electrode izinhlayiya omubi icala bakhangwa yi kagesi amabutho field kuya electrode omuhle phansi. I izinhlayiya kahle icala badonseleka omubi icala electrode phezulu. Ijubane lale okuqhubekayo iluphu ibhande kuyinto variable kusuka 4 ukuze 20 m / s. Ijiyomethri yezintambo zebhande eziwela ukuqondisa zisebenza ukushanela izinhlayiya zama-electrode eziwahambisa ngasekugcineni okufanele kwesihlukanisi futhi abuyele endaweni ephakeme yokugunda phakathi kwezingxenye ezihamba ngokuphambene zebhande.. Ngoba kwabantu inombolo kuyizinhlayiyana kuphezulu ngakho ngaphakathi igebe phakathi electrode (cishe ingxenye eyodwa kwezintathu umthamo ugcwele izinhlayiya) futhi ukugeleza is ngamandla ukuyaluza, kukhona ukushayisana abaningi phakathi izinhlayiya kanye ukushaja elilungile kwenzeka njalo kulo lonke indawo ngokuhlukana. Ukugeleza kwamanje okuphikisayo okubangelwa izigaba zamabhande anyakazayo kanye nokushajwa kabusha nokuhlukaniswa kabusha okuqhubekayo kudala ukuhlukana okuphikisayo kwezigaba eziningi ngaphakathi kwe-apathasi eyodwa.. Lokhu kushaja okuqhubekayo nokushajwa kabusha kwezinhlayiya ngaphakathi kwesihlukanisi kuqeda isidingo sanoma iyiphi isistimu “yeshaja” ngaphambi kokwethula okubalulekile kusihlukanisi., ngaleyo ndlela kususa umkhawulo ongathi sína kumthamo wokuhlukaniswa kwe-electrostatic. Okuphuma lokhu isihlukanisi kuyinto ukusakaza ezimbili, ukugxilisa ingqondo, kanye ezisalayo, ngaphandle ekusakazeni middlings. Ukusebenza kahle lokhu isihlukanisi esiye lufana cishe ezintathu izigaba ukuwa ngokwahlukana nge middlings kabusha.

Isihlukanisi se-STET sinezinqubo eziningi eziguquguqukayo ezivumela ukuthuthukiswa kokuhwebelana phakathi kokuhlanzeka komkhiqizo nokutholakala okutholakala kunoma iyiphi inqubo Yokuzuza.. Ukulungiswa kwamaholoholo imbobo yokuphakelayo lapho okuphakelayo kwethulwa khona egumbini lokuhlukanisa. Ichweba elikude kakhulu ne-hopper yokukhipha yomkhiqizo owufunayo inikeza izinga elingcono kakhulu kodwa ngezindleko zokuthola kabusha okuphansi.. A zikanokusho ukulungiswa kuyinto ijubane ibhande. Igebe le-electrode, okuyinto adjustable phakathi 9 futhi 18 mm, futhi voltage isicelo (± 4 kuya ± 10 kV) nazo eziguquguqukayo ezibalulekile. I polarity of the electrode singashintshwa okuyinto izinsiza in ukwehlukana ezinye izinto. Ukulungiswa kusengaphambili kwezinto eziphakelayo ngokulawula okunembile kokuqukethwe komswakamo (njengoba kulinganiswe okuphakelayo umswakama nesihlobo) kubalulekile ukuzuza imiphumela yokuhlukana esezingeni eliphezulu. Ukwengezwa kwamanani omkhondo wama-ejenti amakhemikhali ashintsha inkokhiso nakho kungasiza ekwandiseni inqubo.

Njengoba kushiwo ngenhla, ukusetshenziswa kokuqala kwezentengiselwano kwesihlukanisi sebhande kube ukuhlukaniswa kwelahle lamalahle kumaminerali ayingilazi ye-Aluminosilicate kusuka kumlotha wezimpukane ezitshalweni zamandla aphehlwa ngamalahle.. Lobu buchwepheshe buhlukile phakathi kwezihlukanisi ze-electrostatic ekhonweni layo lokuhlukanisa umlotha wempukane, okuyinto ngokuvamile has a usayizi kusho kuyizinhlayiyana esingaphansi 0.02 mm. Isihlukanisi se-STET siphinde safakazelwa ukuthi sihlukanisa ngempumelelo i-magnesite ne-talc, i-halite evela ku-kieserite ne-sylvite, silicates kusukela Bart, kanye nama-silicates avela ku-calcite.3 Usayizi wezinhlayiyana omaphakathi wazo zonke lezi zinto zokuphakelayo ubusebangeni lokuthi 0.02 futhi 0.1mm. Izibonelo abahlukanisayo wempahla eziningana afakiwe Ithebula 1.

Ithebula 1 - Isibonelo Separations

Ukwahlukana	Okuphakelayo	umkhiqizo	lokutakula
I-calcium carbonate - Ama-silicates	9.5% I-Acid Insols	<1% A.I.	89% I-CaCO3
talc - Magnesite	58% talc	95% talc	77% talc
		88% talc	82% talc
I-Kierserite + I-KCl - NaCl	11.5% K2O	27.1% K2O	90% K2O
	12.2% kieserite	31.8% kieserite	94% kieserite
	64.3% NaCl	14.3% NaCl	92% I-NaCl yenqaba
I-Fly Ash Mineral - carbon	6.3% carbon	1.8% carbon	88% amaminerali
	11.2% carbon	2.1% carbon	84% amaminerali
	19.3% carbon	2.9% carbon	78% amaminerali

Okwazekayo, kusukela kuyizinhlayiyana ukushaja kuxhomeke umphumela triboelectric, iyiphi amaminerali ezimbili bayakhululwa nomunye (umqhubi- umqhubi noma nonconductor-umqhubi) kungenziwa ahlukaniswe le ndlela. Ezinye izinhlelo zokusebenza ezingaba zihlanganisa Magnesite-asebenza ngebhethri, feldspar-asebenza ngebhethri, Sands amaminerali, nezinye abahlukanisayo umanyolo amaminerali, futhi
Phosphate-calcite-Silica abahlukanisayo.
