Iziteshi ezijikelezayo zibe yingxenye ebalulekile kubuchwepheshe bokucubungula imayini besimanje, ikakhulukazi ekubuyiseni kahle imayini ye-ultra-fine. Embonini yokumba, ukuhlela izinga lokubuyisa ngenkathi kugcinwa ukusebenza kahle kwamandla nokunciphisa izindleko zokusebenza kuyizinjongo ezibalulekile. Le ndatshana ihlinzeka ngombono ophelele weziteshi ezijikelezayo, ibonisa incazelo yazo, izinzuzo, izicelo, izindlela zokusebenza, kanye nezinzuzo ezihambisana nezinye izinhlelo zokucubungula imayini. Sizophinde sikhombise izindlela ezinhle zokusebenza futhi sithinte imibuzo evamile ukusiza amabhizinisi kanye nochwepheshe ukwenza izinqumo ezicacile mayelana nokwamukelwa kweziteshi ezijikelezayo.

I-chute ye-spiral iyithuluzi lokubuyisela imayini elisebenzisa isisindo, elakhiwe ukuze ihlukanise futhi igxile ezindaweni ezincane nezincane kakhulu ezivela kumaminerali nasemathinini. Iqukethe ithafa elijikelezayo lapho i-slurry ifakwa phezulu, ihamba phansi ngaphansi kwesikhala. Njengoba i-slurry ihamba endleleni ye-spiral, amandla e-centrifugal enza ukuthi ama-particulate amaminerali anzima ahambe ngaphakathi kwe-chute, kanti ama-gangue alula ahamba ngaphandle. Le msebenzi ehlukile ivumela ukuhlukaniswa kahle kwamaminerali abalulekile emathinini. Ama-chute e-spiral alula ekwakhiweni kodwa asebenza kahle kakhulu, okwenza asetshenziswe kabanzi ezitshalweni zokucubungula imayini emhlabeni jikelele.

Imishini eyisisekelo ibandakanya ukuhamba okulawulwayo kwe-slurry kanye nezici zokuhlala kwezinto ezincane ngokusekelwe ekuhlukanisweni kwazo. Ngokulungisa izinga lokudla kanye nokudilizwa kwamanzi, abaphathi bangathuthukisa ukusebenza kahle kokuhlukaniswa, okuvumela ukuvuselelwa kwezinsimbi ezivame ukuphuthelwa ngezindlela zendabuko ezifana nezitayela zokushaya noma izinhlelo ze-chute eziphakanyisiwe. Inqubo yomzimba yokuhlukaniswa esetshenziswa ama-chute aphindwe kabili inciphisa isidingo sezithako zamakhemikhali, ngaleyo ndlela isekela imisebenzi yokuvuselela izinsimbi ezihambisana nemvelo.

Omunye wemivuzo ebaluleke kakhulu ye-spiral chutes ukukwazi kwawo ukuvuselela kahle amaminerali amancane kakhulu angavuthiwe, avame ukuba nzima ukuwahlukanisa ngama ndlela ajwayelekile. I-spiral chutes iklameka kahle ekuvuseleleni amaminerali alahlekile njenge-tailings, okwenza kube kubalulekile kakhulu ekuthuthukiseni izinga lokuvuselela jikelele nasekunciphiseni ukulahleka kwezinsiza. Umklamo wabo uvikela ukuhlukaniswa komzimba kwamaminerali kusetshenziswa isisindo namandla e-centrifugal ngaphandle kokudinga imishini eyinkimbinkimbi noma edla amandla amaningi.

Ukusebenza kahle kwamandla kuyinzuzo ebalulekile. Ama-spiral chutes asebenza ngokusebenzisa isisindo, akhipha isidingo sokusebenzisa amandla kagesi noma imishini ethatha amandla amaningi. Lokhu akunciphisi kuphela izindleko zokusebenza kodwa futhi kusiza ezindleleni zokumbiwa ezisimeme ngokwehlisa umthelela wemvelo emisebenzini yokucubungula imayini. Ngaphezu kwalokho, izidingo zazo eziphansi zok maintenance kanye nokwakhiwa kwazo okuqinile kuqinisekisa ukwethembeka kwesikhathi eside nokwehliswa kwesikhathi sokungasebenzi, okwenza ama-spiral chutes abe yisixazululo esisebenzayo kwezokubuyiselwa kwemayini.

Iziteshi ezijikelezayo zisetshenziswa kabanzi ekubuyiseleni izinhlobonhlobo zezimbiwa, kuhlanganise negolide, i-hematite, itini, nezinye izinsimbi ezincane nezincane kakhulu. Zisebenza kahle ikakhulukazi ekucubunguleni ama-tailings kanye nezinsimbi ezisezingeni eliphansi lapho izindlela zokuhlukanisa ezijwayelekile zingase zihluleka ukubuyisela izimbiwa ezibalulekile. Ukuguquguquka kweziteshi ezijikelezayo kuvumela ukusetshenziswa kwazo ezindaweni ezahlukene zokumbiwa, kuhlanganise nezinsimbi eziyigugu, izinsimbi zezimboni, futhi ngisho nokulungiselela ikholi.

Imboni izuza kumachute aphindwe kabili ngokuthuthukisa izinga lokubuyiselwa kwemaminerali ngenkathi kuncishiswa umthelela kwemvelo. Isibonelo, emkhakheni wezokumbiwa kwensimbi, amachute aphindwe kabili abuyisela kahle amafutha egolide aphansi ezinsizakusebenza, kuthuthukisa inzuzo. Ngaphezu kwalokho, ikhono lawo lokuphatha ama-ore amanzi, anamathelayo lenza afaneleka ezisebenzelaneni nezinhlobo ze-ore eziyinkimbinkimbi. Ukusebenza kwawo okubanzi kanye nokulula kokusebenza kwamachute aphindwe kabili kwenza kube ithuluzi elisebenzayo lokubuyiselwa kwemaminerali ezimbonini ezahlukene.

Ukusebenza kwe-spiral chute kuqala ngokudla okulawulwayo kwe-slurry phezulu kwe-spiral trough. I-slurry ivamise ukuba yihlanganiso ye-ore egayiwe kahle kanye namanzi, edlula phansi ngenxa yokudlula komhlaba endleleni ye-helical ye-spiral. Njengoba impahla ihamba, amandla e-centrifugal asebenza kumaphakethe ngokusekelwe kumasondo awo athile, okwenza amaminerali anzima ahambe ngaphakathi emgqeni wangaphakathi we-chute, kanti amaphakethe alula ahamba ngaphandle.

Inqubo yokuhlukanisa ithonywa ngesivinini sokudla, ubunzima besilayidi, i-engeli yokuphakamisa, kanye nokugeleza kwamanzi. Ukulungiswa kahle kwalezi zinkomba kuthuthukisa ijubane lokuhlala kwezinto, kukhuthaza ukuhlukaniswa okusebenzayo. I-spiral chute ivamise ukuba nezigaba eziningi noma ama-spirals ukuze ikhulise isikhathi sokuxhumana futhi ithuthukise ukunemba kokuhlukanisa. Emaphahleni, ama-concentrates e-mineral ahlukanisiwe kanye ne-tailings aqoqwa ezindaweni ezibekelwe ukuze aqhutshekwe noma aphume.

I-spiral chutes ihlanganyela nezici ezifanayo ne-spiral concentrators, kodwa kunezinguquko ezihlukile ezithinta ukusetyenziswa kwazo. Ngenkathi kokubili kusebenzisa isisindo namandla e-centrifugal ukuze kuhlukaniswe, i-spiral concentrators ivame ukufaka ama-riffles noma ezinye izici zomshini ukuze kuthuthukiswe ukuvuselelwa kwezinhlayiya ezincane. I-spiral chutes, ngakolunye uhlangothi, ithembele emgqeni opholile, okunciphisa ukugcinwa nokusebenza okunzima.

Uma kuqhathaniswa nezitolo ezishukumisayo nezinhlelo zokuhambisa ezine-felt, ama-chute aphindwe kabili anikeza ukukhiqiza okuphezulu nokusebenza okulula. Inqubo yabo yokwehlukanisa ngokomzimba ivumela ukuvuselelwa kwezimayini ezincane kakhulu ngaphandle kwezithasiselo zamakhemikhali, okuthuthukisa ukusebenza okuthintekayo kwemvelo. Ngaphezu kwalokho, ama-chute aphindwe kabili kulula ukuwakhulisa nokuwahlanganisa ezinhlelweni zokucubungula izimayini ezikhona, kunikeza ukuhamba nokonga izindleko uma kuqhathaniswa nezinhlelo eziyinkimbinkimbi noma ezidinga amandla amaningi.

I-chute ye-spiral imele isixazululo esisebenza kahle kakhulu, esisebenzisa amandla kancane, futhi esidinga ukugcinwa okuncane ekubuyiseni imayini, ikakhulukazi efanelekile kumaminerali amancane kakhulu. Ikhono lawo lokubuyisa imayini ewusizo ezivunguzelweni nasemayini anokwehla kwenani lenzuzo lenza kube kubalulekile emisebenzini yokumba yanamuhla efuna imiphumela esimeme futhi enenzuzo. Ukuze kuthuthukiswe izinzuzo, abaphathi kufanele bagxile ekuthuthukiseni izinga lokudla, ukugxila kwe-slurry, kanye nezincline ze-chute ngenkathi beqinisekisa ukugcinwa okuvamile ukuze kugcinwe ukusebenza.

Ukukhetha ama-spiral chutes aphezulu avela kubakhiqizi abahloniphekile njengeAlicoco Mineral Technology Co., Limitedkuqinisekisa ukusebenza okuthembekile nokwesekwa. I-Alicoco igxile kumklamo we-spiral chute onamalungelo obunikazi okugcizelela ukuphuma kahle, ukuqina, nezixazululo zokumba ezihlonipha imvelo. Ukuze uthole imininingwane ethile mayelana nemikhiqizo kanye nezixazululo zokucubungula ezenziwe ngezifiso, uvakashele i-Imikhiqizoikhasi linconywa.

I-spiral chutes iyasebenza ekubuyiseni imayini ezincane nezincane kakhulu ezifana negolide, i-hematite, itini, i-ilmenite, nezinye izimayini ezinzima ezivame ukutholakala kumathala nezinsalela eziphansi.

Ngenkathi kokubili kusebenzisa isisindo sokuhlukanisa, ama-spiral chutes anenhlangano ethambile ye-helical ngaphandle kwe-riffles, okuholela ekugcinweni okulula, kuyilapho ama-spiral concentrators angase abe nezici zokwandisa ukuvuselelwa kwezinhlayiya ezincane.

Yebo, ama-spiral chutes ayakwazi ukusetshenziswa ezindaweni ezahlukene kufaka phakathi ukutholwa kwezinsimbi ezibalulekile, imayini yezimayini zezimboni, ukulungiswa kwekhabhoni, nokusebenza kokuphinda kusetshenziswe.

I-spiral chutes idinga ukugcinwa okuncane, ikakhulukazi okuhlanganisa ukuhlanza njalo ukuze kuvinjelwe ukuvuvukala, ukuhlola ukugqokwa nokulimala, nokwenza uqinisekise ukuhamba kwamanzi kahle kanye nezinga lokudla.

Izinkampani ezifana neAlicoco Mineral Technology Co., Limitednikela ngezixazululo ezine-patent nezithembekile ze-spiral chute ezihlelwe ngezidingo ezihlukahlukene zokucubungula imayini.

Ngemininingwane eyengeziwe ethile mayelana neziteshi ezijikelezayo, ubuchwepheshe bokubuyiselwa kwemaminerali, kanye nemikhiqizo ehlobene, cabanga ngokuhlola lezi zinsiza ezihlinzekwe yi-Alicoco:
