I-spiral concentrator ingumshini wokuhlukanisa ngezinto ezinzima (gravity separation) ocubungula izingxube zezinto eziyisihlabathi (mineral slurries) ngomsele oyindilinga (helical trough) ozungeze insika emaphakathi emi mpo. Lapho uketshezi olungenayo lungena phezulu kwi-spiral, izinhlayiya zezinto ezinzima (heavier mineral particles) zithuthela onqenqemeni lwangaphakathi lomsele kuyilapho izinto ezilula (lighter gangue materials) ziphushwa ziye onqenqemeni lwangaphandle ngamandla e-centrifugal kanye nokugeleza kwamanzi. Umphumela wukuhlukaniswa okuqhubekayo, okusebenza kahle kakhulu okungadingi izingxenye ezinyakazayo, akudingi amakhemikhali, futhi kusebenzisa amandla amancane kakhulu. Amayunithi esimanje e-spiral angacubungula amathani amaningi we-ore ngehora nge-spiral ngayinye, okwenza kube ngumgogodla wezinhlelo eziningi ze-gravity emhlabeni wonke. Noma ngabe usebenza ne-iron ore, i-tin, igolide, noma isihlabathi sasolwandle, ukuqonda amandla alesi sisetshenziswa kubalulekile ekwakheni indawo yokucubungula ethembekile. Lesi sihloko sinikeza ukubuka okuphelele kobuchwepheshe be-spiral futhi sichaza ukuthi kungani i-Alicoco Mineral Technology Co., Limited isungule ukuthenjwa njengomkhiqizi kulo mkhakha.

Umlando we-spiral concentrator ubuyela emuva eminyakeni yawo-1940, lapho amayunithi okuqala asebenzayo akhiwa njengendlela elula futhi eshibhile kunama-shaking table nama-jig avamile. Imiklamo yakuqala yakhiwa nge-saw spiral profile elula egxilwe ezinsimbi zensimbi noma ezingodlweni zokhuni, okwakunciphisa ukuqina kwayo namandla okukhiqiza. Emashumini eminyaka alandelayo, abakhiqizi bathuthukisa i-geometry yomsele, bethula ukwakhiwa kwe-fiberglass ne-polyurethane, futhi banezela ama-splitter aguquguqukayo anika abasebenzi ukulawula okunembile kwekhwalithi yomkhiqizo. Ngeminyaka yawo-1980 nayawo-1990, i-computational fluid dynamics yaqala ukwazisa umklamo wama-spiral anamuhla, okuholela ekuhambeni kwe-flow okubushelelezi kanye namazinga aphezulu kakhulu okuthola kabusha. Imishini yanamuhla, okuhlanganisa nokwakheka kwe-Ringu spiral entsha okusetshenziswa kwezinye izimboni ezithuthukile, iletha ukusebenza okwakungacabangeka kubonjiniyela bakuqala. Ukuguquka kwale mishini kubonisa umkhuba obanzi wemboni wokuthuthukisa ubuchwepheshe obuncane, obonga izindleko, nobunobungani nemvelo, futhi ukuze uthole umbono ophelele wenkampani yethu nemikhiqizo yethu, ungasiqala ekhasi lethu lasekhaya (Home page) futhi uhlole imenyu yokuzulazula.

Umthetho wokusebenza we-spiral concentrator usekelwe kumthetho we-physics wokwehlukaniswa ngamandla adonsela phansi (gravity separation), lapho umehluko wokuminyana kwezinhlayiyana usetshenziswa kufilimu elincane lamanzi agelezayo. Njengoba i-slurry ihamba phansi komgudu oyindilinga (helical channel), amandla e-centrifugal, amandla adonsela phansi, kanye nokudonswa kwamanzi (fluid drag) kusebenza kanyekanye kuzo zonke izinhlayiyana, zihlungwa ngokuminyana kwazo (specific gravity) kunokuba kube ngosayizi kuphela. Amaminerali asindayo afana ne-magnetite, i-cassiterite, ne-zircon agcina ngokujula ngokushesha phansi komsele (trough), lapho isivinini samanzi esinciphile sivumela ukuthi anqwabelane ngaphakathi komgudu. I-quartz elula nezinhlayiyana zobumba, ngokuphambene, zihlala zintanta emfuleni ongaphandle ohamba ngesivinini esikhulu futhi zikhukhulelwa ziye phansi lapho kukhishwa khona i-tailings onqenqemeni olungaphandle. Ukujika okuphindaphindiwe kwe-helical kukhulisa umphumela wokuhlunga ngokwe-radial, ngakho ngisho nezinhlayiyana ezinomehluko omncane wokuminyana zingahlukaniswa ngokungaguquguquki okuphawulekayo. Ngenxa yokuthi le nqubo isebenzisa amanzi namandla adonsela phansi kuphela, ayikhiqizi ukungcola kwamakhemikhali futhi idla ingxenye encane yamandla adingwa yi-froth flotation noma i-magnetic separation, okuyinzuzo enkulu kulabo abagxile ekusimameni (sustainability-minded operators).

I-siparatha esimanjemanje esiyispiral sakhiwe ngezingxenye ezimbalwa eziklanywe ngokucophelela ezisebenza ndawonye ukukhulisa ukusebenza kahle. Ibhokisi lokudla eliphezulu lithola i-slurry evela ohlelweni lokusabalalisa futhi liyisakaza ngokulinganayo ububanzi bomsele, okubalulekile ekwehlukaniseni okungaguquki kuwo wonke umsele. Umsele oyispiral ngokwawo wenziwe ngezigaba nge-polyurethane engaguquki noma i-fiberglass, futhi ukuma kwawo, ngokuvamile okunomumo we-parabolic noma we-elliptical cross section, kunquma ukuthi izinhlayiya zihlukaniswa kanjani njengoba zehla. Onqenqemeni lwangaphandle, ama-product splitters nama-adjustable cutters avumela abasebenzi ukuqondisa i-concentrate, ama-middlings, nama-tailings emigceleni ehlukene ngaphandle kokumisa umshini. Insika emaphakathi isekela lonke uhlelo futhi inikeza uhlaka oluqinile olungafakwa emazingeni amaningi, okwenza insika eyodwa ikwazi ukubamba ama-spiral starts amaningi. Izindawo zokwengeza amanzi okuhlanza zifakwa lapho kudingeka khona ukuthuthukisa ukutholakala kwezinhlayiya ezincane, futhi yonke iyunithi iklanyelwe ukusebenza ngaphandle kokugadwa isikhathi eside ngokuqapha okuncane.
