I-Gravity separation iseyelokhu ihlala ingenye yezindlela ezingabizi kakhulu futhi ezinobungane emvelweni ekucutshungulweni kwamaminerali isikhathi esingaphezu kwekhulu leminyaka, incike emehlukweni okuminyana ukuze ihlukanise amaminerali abalulekile kuma-gangue. Phakathi kwama-gravity concentrators ahlukahlukene atholakalayo, i-spiral chute igqama njengeyona esebenza kanzima ekucubunguleni izinto zokudla ezincane neziphakathi kuma-gold, tin, iron, kanye nasezindaweni zokusebenza zesihlabathi solwandle. Leli thuluzi lisebenzisa inhlanganisela yamandla e-centrifugal, ukudonsa koketshezi, kanye nokumelana nokungqubuzana ukudala ukugeleza kwezinhlayiya okuhlukanisiwe okugcina kukhiqize ama-concentrates ahlanzekile, ama-middlings, kanye nama-tailings. Nokho, ukusebenza kwanoma iyiphi i-spiral chute akusona nje udaba lokuthenga ama-hardware asetshenzisiwe, ngoba ngisho izinguquko ezincane ku-geometry zingashintsha kakhulu amazinga okubuyiswa kanye namabanga omkhiqizo. Ngenxa yalokho, ukuthuthukiswa kwedizayini sekuphenduke umkhakha obalulekile ohlukanisa izitshalo eziphumelelayo kulezo ezingasebenzi kahle, futhi kufanele zinakekelwe ngokucophelela yibo bonke onjiniyela bamaphrojekthi kanye nabaphathi bezitshalo. Kulesi sihloko, sizohlaziya amapharamitha ayisisekelo esakhiwo alawula ukuziphatha kwe-spiral chute, sichaze ukuthi athonya kanjani ukusebenza kahle kokuhlukanisa, futhi sinikeze isiqondiso esisebenzayo sokukhetha ithuluzi elifanele iphrojekthi yakho.

I-spiral chute iyisitsha esingumhelix, ngokuvamile esakhiwe nge-fiberglass reinforced plastic, irabha, noma insimbi, esihambisa i-slurry yamanzi nezinhlayiyana eziqinile phansi ngendlela eyi-spiral ngaphansi komthelela wamandla adonsela phansi. Njengoba i-pulp igeleza emseleni ogobile, amandla e-centrifugal aphushela izinhlayiyana ezisindayo ngasemaphethelweni angaphakathi kuyilapho izinhlayiyana ze-gangue ezilula zihamba ngasemaphethelweni angaphandle, zakhe iphethini ehlukile yemigqa ehlukene. Amanzi okugeza angeniswa eceleni kwangaphakathi ukuze asize ekuthutheni izinto ezinokuminyana okuphansi, kuyilapho i-concentrate yamaminerali asindayo iqoqwa ngezinhlobonhlobo zama-splitter noma ama-cutter abekwe phansi kwijika ngalinye. Umgomo oyisisekelo wale divayisi ukuhlukaniswa ngamandla adonsela phansi, lapho umehluko ku-specific gravity, usayizi wezinhlayiyana, kanye nokuma kunquma ukuthi isinhlayiyana ngasinye siphendula ngokushesha kangakanani emandleni ancintisanayo e-drag, i-inertia, nokugeleza koketshezi. Ngenxa yokuthi awekho amakhemikhali adingekayo futhi amanzi avele asetshenziswe kabusha, ama-spiral concentrator aziwa kabanzi njengesixazululo esingayonakalisi imvelo futhi esinezindleko eziphansi zokusebenza ezitshalweni zanamuhla zokucubungula amaminerali. Yingakho i-spiral chute isiphenduke ingxenye ejwayelekile kuma-flowsheet e-chromite, i-ilmenite, i-rutile, i-zircon, kanye nenqwaba yezinye izinhlelo zokusetshenziswa zamaminerali asindayo emhlabeni wonke.

Ekuhambeni kwansuku zonke, i-spiral chute isebenza ngezinto eziqinile zokudla ezisukela ku-0.03 mm kuya ku-6 mm, okubeka ngqo phakathi kwamandla okucubungula okukhulu kwama-jigs kanye nokubuyiselwa okuncane kakhulu okwenziwa ama-shaking tables noma ama-flotation cells. Ngaphandle kokuhlukanisa amaminerali ngamanye, lawa mayunithi asetshenziselwa futhi ukususa udaka, ukugxilisa kuqala, kanye nemisebenzi yokuhlanza, okuwenza abe nokusebenza okuguquguqukayo okukhulu kumjikelezo wokugqoka. Izinkampani eziningi zezimayini zifaka ama-spiral chute amaningi ngokuhambisana ukuze zithole umthamo ophezulu odingwa izitshalo zokucubungula ezinkulu, futhi zivame ukuxhumanisa izigaba eziningi ndawonye ukuze zicwengise ukugxila kancane kancane. Ukusebenza kahle kokuhlukaniswa ngamandla adonsela phansi ku-spiral kuncike kakhulu ekugcineni kwesilinganiso sokudla esizinzile, izinga lokugeleza kwe-pulp elingaguquki, kanye nokulungiselelwa okufanele kwe-splitter, konke okufanele kuhambisane nezici zesakhiwo semishini. Lapho lezi zimo zihlanganiswa kahle, i-spiral chute eklanywe kahle ingafinyelela amazinga okubuyisela angaphezu kuka-90% kumaminerali asindayo agayeka kalula, okuchaza ukuthandwa kwayo okuhlala njalo embonini yonke. Ngakho-ke, ukuqonda kokubili ukwakhiwa komshini kanye nezinto eziguquguqukayo zokusebenza kubalulekile kunoma ubani ohlose ukwandisa inzuzo yokukhiqiza.

I-diameter ye-spiral ingenye yezinto ezibonakalayo kakhulu ezihlukanisayo, futhi osayizi abajwayelekile bezimboni basukela ku-600 mm kuya ku-1500 mm, futhi inquma ngqo umthamo kanye namandla e-centrifugal asetshenziswa ku-slurry. I-diameter enkulu idala ijika elithambile, elinciphisa i-radial velocity gradient futhi livumele izinhlayiya ezincane ukuthi zihlale ngendlela eqagelayo, okwenza ama-spiral ane-diameter enkulu abe ngcono ekudleni okucolekile nasekusetshenzisweni kokuhlanzeka okuphezulu. Ngakolunye uhlangothi, i-diameter encane idala amandla e-centrifugal anamandla akhuphula umthamo kodwa ingase ilahlekelwe ukubuyiselwa kwamaminerali abucayi noma aseduze nokuminyana, ngakho-ke onjiniyela kufanele balinganisele lezi zinto ngokucophelela. I-pitch, okusho ukwehla okuqondile kwe-helix ngomjikelezo ogcwele, ilawula isivinini se-pulp njengoba ihamba phansi futhi ngaleyo ndlela ithinta isikhathi sokuhlala esitholakalayo sokuhlukanisa. I-pitch enyukayo isheshisa ukugeleza, ikhulise ukusebenza kodwa ngesikhathi esifanayo inciphise isikhathi sokuthintana futhi yenze inqubo yokugeleza ibe nesiphithiphithi futhi ingakhethi kahle. Ngakolunye uhlangothi, i-pitch engajulile yehlisa isivinini se-pulp, ithuthukise ukuhlungwa kwezinhlayiya kodwa yehlise umthamo wokucubungula, okukhulisa inani lamayunithi adingekayo ukuze kufinyelelwe umgomo wokukhiqiza othile. Ukukhetha inhlanganisela efanele ye-diameter ne-pitch ngakho-ke kudinga ukuqonda okucacile kwezici zokudla kwakho, umthamo wokukhiqiza ohlosiwe, kanye nezinga elifunwayo le-concentrate yokugcina.

Isimo esiphambanayo somsele, esivame ukubizwa nge-profile, singesinye isici esibalulekile sokuklama esinquma ukuthi i-slurry isabalalisa kanjani ngokwayo phezu kwendawo yomsele. Ama-spiral amaningi esimanje asebenzisa i-ellipse elungisiwe noma inhlanganisela yendawo yangaphandle eyi-elliptical nendawo yangaphakathi eyisicaba, okukhuthaza ukugeleza okucacile futhi kukhiqize ukubanda okuzinzile kwezingxenye ezisindayo nezilula. Umthambeka wangaphansi komsele, ikakhulukazi i-engeli yemiphetho yangaphakathi nangaphandle, ithonya ukulingana phakathi kwamandla e-centrifugal nokushibilika okubangelwa amandla adonsela phansi, futhi ingalungiselelwa ukuhambisana nesisindo esithile samaminerali okuhlosiwe. Ngaphezu kwalokho, inani nendawo yejometri yezihlukanisi zomkhiqizo kunomthelela omkhulu ekubukhali kokusikwa, njengoba zihlukanisa ngokomzimba i-concentrate kusuka kuma-tailings ekhoneni ngalinye. Ngokulungisa izindawo ze-radial zalezi zihlukanisi, abasebenzi bangashintsha izinga le-concentrate ngesikhathi sokusebenza ngaphandle kokumisa isitshalo, okubenza babe yithuluzi elinamandla lokuthuthukisa inqubo. Zonke lezi zinto eziguquguqukayo zejometri zisebenzisana nezici zoketshezi, ngakho ukuma komsele okusebenza kahle kakhulu ku-cassiterite kungase kungafaneleki neze ku-magnetite, okugcizelela isidingo sobunjiniyela obenzelwe umuntu ngamunye.

Inombolo yamajika ku-spiral chute ilawula ngqo ukuthi ingakanani amathuba anikezwa umgqugquzelo wokuzihlukanisa kabusha nokuzihlanza, futhi ukuhlelwa okujwayelekile kusukela kumajika amathathu kuya kwayisikhombisa kuye ngokusetshenziswa. Inombolo enkulu yamajika inikeza ibanga lokuhamba elandisiwe, okuthuthukisa ukusebenza kahle kokuhlukanisa ekuphakelweni okunzima futhi kuveze i-concentrate ehlanzekile, kodwa futhi kwandisa ubude besikhathi seyunithi futhi kudinga isikhala esengeziwe esakhiweni sokusetha isitshalo. Amanye ama-spiral asebenza kahle kakhulu asebenzisa amajika ezigaba lapho ingxenye yokuqala isebenza njenge-concentrator kanti izingxenye zakamuva zenza ukuhlanza, okuhlanganisa ngempumelelo izinyathelo eziningi zenqubo ngaphakathi kwesikhathi esisodwa semishini. Ubude besikhathi sokuhlanganisa, kufaka phakathi ibhokisi lokudla kanye ne-collecting launder, kunquma indawo yesitshalo kanye nezidingo zokusekelwa kwesakhiwo, ngakho abaklami kufanele bavumelanise ukusebenza kwe-metallurgical nezithiyo zobunjiniyela bomphakathi. Okubalulekile, amakholomu e-riser phakathi kwamajika kufanele abekwe ngokucophelela ukuze kugwenywe isiyaluyalu futhi kugcinwe ukuhamba okushelelayo kwe-slurry ukusuka kwelinye izinga kuya kwelinye. Ukuthola inombolo efanele yamajika kuhlale kuncike endaweni, futhi abakhiqizi abadumile batusa ukusebenzisa izivivinyo ze-pilot ukuqinisekisa ukuhlelwa ngaphambi kokuzibophezela ekuthengeni okugcwele.

Indlela yokwakha ye-spiral ayithinti nje kuphela ukuqina kwayo kodwa futhi nezici zokungqubuzana ezitholwa yi-pulp egelezayo, okubuye kube nomthelela ekubunjweni kwe-velocity profile kanye nekhwalithi yokuhlukanisa. I-Fiberglass reinforced plastic iyisinqumo esivame kakhulu ngoba ilula, iyamelana nokugqwala, futhi ingabunjwa ibe yindawo yomsele ebushelelezi kakhulu enciphisa isiyaluyalu esingadingekile. Ama-Polyurethane kanye nama-rubber linings avame ukufakwa ezinhlelweni ezigqagqayo ukuze kwandiswe isikhathi sokusebenza futhi kuvikelwe isakhiwo esiyisisekelo ekugugeni okubangelwa ama-slurry amaminerali anokuminyana okuphezulu. Ukuqedwa kwendawo nakho kubalulekile: umsele obushelelezi, ocwebezelisiwe uvumela izinhlayiya ukuthi zishelele ngokuphazamiseka okuncane, kuyilapho izindawo ezimahhadlahhadla zingabamba izinhlamvu eziyigugu futhi zibangele ukuziphatha kokugeleza okungazinzi. Abanye abakhiqizi manje banikeza ama-surface textures enziwe ngokwezifiso akhuthaza ukuziphatha okuthile kwezinhlayiya, njengokuthuthukiswa kokugeleza kwefilimu ukuze kutholakale okuncane kakhulu, okubonisa indlela isayensi yezinto ezisetshenziswayo esezingeni eliphezulu ethuthukisa ngayo izindlela zendabuko zokuhlukanisa nge-gravity. Ukuze kube nokuthembeka kwesikhathi eside, ukumelana nokuguga kwe-chute liner kufanele kufaniswe nokugqagqa kwe-ore, futhi ukuhlolwa njalo kwesimo sendawo kuyindlela yokunakekela enconywayo. Ekugcineni, ukukhethwa kwezinto akufanele kube into ecatshangelwa kamuva, ngoba kuthinta ngqo kokubili ukusebenza kahle kokusebenza kanye nezindleko eziphelele zomjikelezo wokuphila kwemishini yokucubungula amaminerali.

Ukusebenzisana phakathi kwejiyometri yesakhiwo kanye ne-fluid dynamics ngaphakathi komsele yisizathu esiyinhloko esenza ukusebenza kwe-spiral chute kuhluke kakhulu ezifakweni ezahlukene. Lapho ububanzi, i-pitch, kanye nokuma komsele kuhambisana kahle, i-pulp yakha iphethini ezinzile, ephindaphindekayo lapho izinhlamvu zamaminerali asindayo zihlala phansi ngokushesha futhi zithuthwe zingene ngaphakathi yi-secondary flow, kuyilapho i-gangue elula ihlala ilenga futhi ihamba ngaphandle. Nokho, uma i-pitch imile kakhulu noma ukuma komsele kungaklanywa kabi, kuvela ama-turbulent eddies axuba kabusha izingqimba ezihlukene futhi ehlisa kakhulu ukucaca kokuhlukaniswa, okuholela ekulahlekelweni okukhulu kwamaminerali abalulekile kuma-tailings. Ngokufanayo, ububanzi obukhulu kakhulu ku-feed enezinhlayiya eziqinile bungase buhluleke ukukhiqiza amandla e-centrifugal anele, okubangela ukuthi izinto ezisindayo zihlale zisakazekile kulo lonke i-cross-section kunokuba ziqoqeke eduze komkhawulo wangaphakathi. Lezi zinkinga zemishini zithonya ngqo umthamo wokucubungula, ngoba i-chute esebenza esimweni esingazinzile kufanele ifakwe ngezinga eliphansi ukuze kugcinwe izinga elamukelekayo, okunciphisa ngempumelelo ukukhiqizwa kwesitshalo. Ucwaningo lwezimboni lubonisa ngokungaguquki ukuthi ijiyometri elungiselelwe kahle ingathuthukisa ukusebenza kahle kokuhlukaniswa ngamaphuzu ambalwa ekhulwini uma kuqhathaniswa nemiklamo ejwayelekile, okuhumusha ekuzuzeni okukhulu kwemali kulo lonke impilo yemayini. Izifundo zezimo zensimu ezivela ezitshalweni ze-polymetallic zibonisa ukuthi ukulungisa izindawo zama-splitter kanye nokuqinisekisa kabusha i-engeli yomsele ngemva kokusebenza ngokuvamile kuveza ukuthuthuka okusheshayo kwezinga le-concentrate ngaphandle kokutshala imali eyengeziwe.

Imininingwane yangempela yokucubungula amaminerali iqinisekisa ukuthi umphumela ohlangene wale mikhawulo ungalinganiswa ngomsebenzi wokuhlola olawulwayo.

I-spiral enamajika amathathu ivamise ukusetshenziselwa ukwehlukanisa okulula noma imisebenzi yokuhlanza lapho umthamo ubaluleke kakhulu kunokugxilisa okuhlanzekile kakhulu. Imodeli enamajika amahlanu inikeza ukulingana okuhle phakathi kokutholakala kanye nezinga, okuyenza ibe yisinqumo esithandwa kakhulu ezinhlelweni ezijwayelekile zamaminerali asindayo. Ama-spiral anamajika ayisikhombisa agcinelwe izidingo zokuhlanzeka okuphezulu noma ukwelapha amaminerali aseduze nokuminyana adinga ibanga lokuhamba elandisiwe ukuze kuzuzwe ukusika okubukhali. Njengoba inombolo yamajika iphinde ithinte ubude besikhathi sayo yonke, kufanele uqinisekise ukuthi ukuhlelwa kwemboni yakho kungakwazi ukwamukela ukuhlelwa okukhethiwe. Ukubonisana nomkhiqizi ofana no-Alicoco kuzokusiza ukuthi unqume inombolo efanele yamajika ngokusekelwe emsebenzini wokuhlola kanye nomgomo wakho othile we-metallurgical.

I-spiral chute idinga ukunakekelwa okuphansi uma kuqhathaniswa nezinye izinhlobo eziningi zemishini yokucubungula amaminerali, kodwa ukuhlolwa okujwayelekile kusadingeka ukuze kube nokusebenza okungaguquguquki. Umsebenzi obaluleke kakhulu ukuhlola ngezikhathi ezithile indawo engaphezulu yomsele ukuze kutholakale izimpawu zokuguga, ukuqhekeka, noma ukuhlukana kwezingqimba, ikakhulukazi emaphethelweni angaphakathi lapho izinhlayiya ezisindayo zigxila khona. Ama-splitter nama-cutter blades kufanele ahlolwe ukuthi akagugi yini futhi alungiswe noma ashintshwe uma kudingeka, ngoba imiphetho egugile ingaphazamisa ukuhlukaniswa okuhle kwe-concentrate kusuka ku-tailings. Kuwukuhlakanipha futhi ukuhlola uhlelo lokusabalalisa ukudla nokuqinisekisa ukuthi i-pulp ilethwa ngokulinganayo kumjikelezo ngamunye, ngoba ukuvaleka noma ukungahambisani kahle kungabangela ukusebenza okungalingani kuyo yonke iyunithi. Ekugcineni, ukugeza i-spiral ngamanzi ahlanzekile ekupheleni kweshifu ngayinye kuzosusa noma yiziphi izinto eziqinile ezihlalile futhi kuvimbele ukunqwabelana okungashintsha izici zokugeleza ngokuhamba kwesikhathi.
