Izi-concentrator ze-spiral zidlala indima ebalulekile embonini yokucubungula amaminerali, ikakhulukazi ekutholeni amaminerali acashile anezinhlamvu ezincane kakhulu. Amaminerali la, avame ukulahleka njengezinsalela ezindleleni ezijwayelekile njengamathebula okudlidliza noma izinhlelo zezimbotshana ezifakwe umuzwa, adinga izindlela zokuhlukanisa ezintsha ukuze kuthuthukiswe amazinga okuthola. Kwa-Alicoco Mineral Technology Co., Limited, izi-concentrator ezikhethekile ze-spiral zenzelwe ukuthuthukisa izinqubo zokuhlukanisa ngokomzimba, ziqinisekise ukuthola ngempumelelo la maminerali anenani futhi zibe nomthelela ekwenzeni imikhuba yokumba esimisweni esisimeme.

Ukugeleza kwezinto ezingamanzi ngaphakathi kwama-concentrator esikhwelo-moya kubaluleke kakhulu kwinkqubo yabo yokuhlela. Ukuzinza kokuhamba kwamanzi kulawula ukwahlulwa kwezimbiwa ngokobunzima nobukhulu njengoko i-slurry ihla esikhwelweni. Indawo yokuhamba kwamanzi ezinzileyo iqinisekisa ukuba iingcali zilandelana neendlela ezingalindelekanga, ziqinisekisa ukwahlulwa ngokuchanekileyo phakathi kwezimbiwa ezixabisekileyo kunye nenkunkuma. Ukungazinzi okanye ukudideka kunokukhokelela ekudibaneni, kunciphise ukusebenza kwe-concentrator. Ukuqonda le miqobo yokuhamba kwamanzi kuvumela abaqhubi ukuba balungise izinto zokusebenza, ngaloo ndlela kuphuculwe ukusebenza kwezimbiwa.

Emigxeni yokuhlanganisa, indlela yokuhlunga ithembele kakhulu ekulinganiseni phakathi kwamandla omfutho womhlaba, amandla okujikajika, namandla okudonsa asebenza ezingxenyeni ezisemanzini. Ukugcina ukuzinza koketshezi kuthinta ngqo ukunemba kokuhlunga, okubaluleke kakhulu lapho kutholwa izingxenye ezincane kakhulu ezithinteka kalula ezishintshweni zokugeleza. Ukuthola ukuzinza okufanele koketshezi kungakhuphula kakhulu inani lemithombo yamaminerali eyigugu, okwenza kube yindawo eyinhloko yokuthuthukisa inqubo.

Izindlela zokuklama kanye nezimo zokusebenza zezikhalipha ezijikajikayo zithinta kakhulu ukusebenza kwazo. Ipharamitha eziningana zidinga ukucatshangelwa ngokucophelela ukuze kuthuthukiswe ukusebenza kahle kokuthola. Okokuqala, ububanzi besikhalipha buqondisa ukuhamba kwezinto kanye nesikhathi sokuhlala samagundane ngaphakathi kwesikhalipha. Ububanzi obukhulu bungakwazi ukubhekana nezinga eliphezulu lokudla kodwa bunganciphisa ukucaca kokuhlukanisa, kanti ububanzi obuncane buthuthukisa ukuhlukanisa kodwa bukhawulela ukukhiqiza.

Isivinini sokudla siyinto ebalulekile futhi. Kumele silinganiselwe ukuze kugcinwe isivinini esanele sokuhlunga izinhlayiya ngaphandle kokudala ukudideka okuyonakalisa ukuzinza koketshezi. Ukulungisa kahle isivinini sokudla kuqinisekisa ukuthi izinhlayiya zamaminerali zithola isikhathi esanele nezimo ezifanele zokuhlukaniswa ngokusekelwe umehluko wamandla nobukhulu.

Ubunzima boketshezelwa (viscosity) boketshezelwa obusetshenziselwa ukuhlunga nabo budlala indima ebalulekile ekuhambeni kwezinhlayiya kanye nesivinini sokuhlala kwazo. Ubunzima obufanele boketshezelwa bukhulisa ukusebenza kahle kokuhlukanisa ngokunciphisa ukuxhuma kwezinhlayiya nokukhuthaza ukwahlukaniswa kwemibuthano. Ekugcineni, isilinganiso sobude obuyindilinga kuya kububanzi (pitch-to-diameter ratio) sesikopolo sithinta ingxenye yamandla omfutho womhlaba (gravitational force) futhi sithonya ukusebenza kahle kokuhlunga kwesikopolo. Ukulungisa lesi silinganiso kuvumela ukwenziwa komshini wokuhlanganisa (concentrator) ukuthi uvumelane nezinhlobo ezithile zamaminerali kanye nemigomo yokusebenza.

Ukwenziwa kahle kokusebenza kahle kwe-spiral concentrator kufaka phakathi inhlanganisela yokuhlolwa kwezivivinyo kanye nezindlela ezithuthukisiwe zokulinganisa. Izindlela zokuhlola zifaka phakathi izivivinyo ezilawulwayo eziguquguqukayo eziguquguqukayo ezifana nobubanzi be-spiral, isivinini sokudla, ukuqina koketshezi, kanye nezilinganiso ze-pitch-to-diameter. Lezi zivivinyo zisiza ukuqoqa idatha yokuhlolwa ngesikhathi sokubuyiselwa kanye nekhwalithi yokuhlukanisa ngaphansi kwezimo ezahlukene.

Ukuqhathanisa, kusetshenziswa i-computational fluid dynamics (CFD), kuqedela izindlela zokuhlola ngokumodela ukuhamba koketshezi kanye nezindlela zamaphilisi ngaphakathi kwe-spiral chute. Le ndlela ephindwe kabili ivumela ukuhlaziywa okunemininingwane kwezindlela zangaphakathi ezithinta ukusebenza, okuvumela ukulungiswa okunembayo kanye nokuthuthukiswa komklamo. Ukuqoqwa kwedatha kuhilela ukuqapha ukwakheka kwezinto ezilahliwe, ukusatshalaliswa kosayizi wamaphilisi, namaphesenti okubuyiselwa, okuhlaziywa ukuze kutholwe amawindi okusebenza afanele.

Ucwaningo lubonisa ukuthi ububanzi be-spiral bunomthelela omkhulu ekusebenzeni kahle kokutholwa kwemaminerali. Ububanzi obukhulu bubasiza ukuthi bacubungule ivolumu enkulu kodwa bunganciphisa ukunemba kokuhlunga ngenxa yezinguquko ekuhambeni kwamanzi. Ngokuphambene, ububanzi obuncane buthuthukisa ukucaca kokuhlukanisa futhi bufaneleka kangcono amaminerali acashile kakhulu. Imiklamo ye-spiral chute ye-Alicoco, enelungelo lobunikazi, ihlanganisa ngokucophelela ububanzi obuhlukahlukene ukuze kuthuthukiswe ukusebenza kwezinhlobo ezahlukene zamaminerali.

Ukulungisa izinga lokugeleza kokudla kubonisa umthelela ocacile ezingeni lokubuyisa. Izinga eliphezulu lokugeleza likhuphula ukukhiqiza kodwa libeka engcupheni ukuphazamisa ukuzinza koketshezi, okuholela ekwehleni kokusebenza kahle kokuhlukanisa. Izinga elifanele lokugeleza livumela izimbiwa ukuthi zihlukaniswe kahle ngaphandle kokudideka ngokweqile, kuthuthukisa ukubuyisa kwezinhlayiya ezinhle. Abasebenzi kufanele balungise izinga lokugeleza ngokusekelwe ekwakhekeni kokudla kanye nomthamo wokucubungula ofunwayo.

Ubunzima boketshezi olusetshenziselwa ukuhlunga bunomthelela ngqo ekuhambeni kwezinhlayiya lapho zihlukana. Ubunzima obuphezulu boketshezi buye buhambise kancane ukunyakaza kwezinhlayiya, bukhuthaze ukuhlukana okungcono futhi kunciphise ukuhlala kwezinhlayiya emanzini. Ama-concentrator akwa-Alicoco azuza emikhubeni yokulungisa uketshezi eshintsha ubunzima bube sezingeni elifanele, ngaleyo ndlela kuthuthukiswe amazinga okutholwa amaminerali anzima ukuhlukana.

Ukulungisa isilinganiso se-pitch-to-diameter kuguqula amandla e-centrifugal asebenza kumagundane nesikhathi sokuhlala ngaphakathi komgqomo. Imiphumela yocwaningo ibonisa ukuthi isilinganiso esilungisiwe sithuthukisa ukuhlungwa kwamaminerali ngokulinganisa imiphumela ye-gravitational ne-centrifugal, okuholela ekubuyiseni okusezingeni eliphezulu. Isilinganiso singalungiswa ukuze sihambisane nezici zamaminerali, sisekela izixazululo ezenziwe ngendlela ye-Alicoco zezidingo ezahlukene zokucubungula.

Ucwaningo olunzulu lwamapharamitha esihlunguli esiyindilinga lugqamisa izincomo eziningana ezingokoqobo zabasebenzi abahlosile ukuthuthukisa ukusebenza kahle kokululama. Ukugcina ukuzinza koketshezi ngokulawula amanani okuphakelayo nokulungiswa kwe-viscosity kuketshezi kubaluleke kakhulu. Ukukhetha ububanzi besihlunguli esifanele kanye nesilinganiso sobubanzi kuya kobubanzi esihambisana nezici zemaminerali kuqinisekisa ukusebenza okungcono kokuhlunga. Lezi zitholakele zivumela izitshalo zokucubungula amaminerali ukuthi zinciphise imfucuza futhi zandise ukululama kwamaminerali anenani, zihambisane nezinjongo zokuzinza komkhakha.

Ngaphezu kwalokho, i-Alicoco Mineral Technology Co., Limited ihlanganisa lezi zinkulumo ekuthuthukisweni kwemikhiqizo yayo, ihlinzeka ngama-spiral concentrators anomklamo onelungelo lobunikazi obuyilungele ukuthola kahle amaminerali amancane kakhulu angalulwa kalula alahlekile ezinhlelweni ezijwayelekile. Ukuzibophezela kwabo ekuqambeni izinto ezintsha kanye nekhwalithi kubenza babe ngabaholi bemboni, banikeze izixazululo eziqotho nezilungele imvelo zokucubungula amaminerali. Ngolwazi oluningiliziwe mayelana nobuchwepheshe babo obuthuthukisiwe, vakashela kuMayelana Nathiikhasi.

Ukuphucula ukusebenza kahle kwe-spiral concentrator kufuna ukuqonda okujulile kwe-fluid dynamics kanye nokwenza kahle kwezici ezakhiweyo nezokusebenza. Izinto ezibalulekile ezifana nobubanzi be-spiral, izinga lokugeleza kokudla, ukuminyana koketshezi lokuhlunga, kanye nesilinganiso se-pitch-to-diameter zithinta kakhulu imiphumela yokubuyisa amaminerali. Ama-spiral concentrators amasha akwa-Alicoco ayisibonelo sendlela ukusebenzisa lezi zindlela okuholela ekubuyiseni okuthuthukisiwe kwamaminerali acashile acashile, kunciphisa udoti futhi kukhuthaza ukucubungula amaminerali okusimeme.

Ngokubheka phambili, ucwaningo oluqhubekayo kanye nentuthuko yezobuchwepheshe izoqhubeka nokuqhakambisa imiklamo ye-spiral concentrator namasu okusebenza, ukuvula ukusebenza kahle okukhulu. Izindawo zokucubungula amaminerali zikhuthazwa ukuba zamukele lezi zinhlelo eziqhakambisiwe nemikhuba ukuze zihlale zincintisana futhi zinomthwalo wemfanelo kwezemvelo. Ukuze uthole imibuzo mayelana nokunikezwa komkhiqizo we-Alicoco nezixazululo zochwepheshe, sicela uvakashele iwebhusayithi yabo ku-Xhumana nathiikhasi.
