I-spiral chute ihlukanisa kwezinye izinto zokusebenza ngamandla adonsela phansi njengamatafula okunyakazisa nama-jig ngokusebenza kwayo okuqhubekayo, amandla aphezulu okucubungula, kanye nezidingo eziphansi zendawo yaphansi. Ngokungafani nama-jig asebenza ngemijikelezo yeqoqo, i-spiral chute icubungula impahla ngokuqhubekayo, okwenza kube yinto efanelekile ezinhlelweni zamathani aphezulu ezitshalweni ezinkulu zokucubungula. Amatafula okunyakazisa anikeza ukubuyiswa kwezinhlayiya ezincane okukhethekile kodwa anamandla aphansi futhi adinga ukunakwa okukhulu komsebenzisi, kuyilapho ama-spiral enikeza ukusebenza okungaguquki ngokuqondisa okuncane. I-spiral chute iphinde isebenze kahle kunezindlela ezijwayelekile zokugeza ngoba ukuhlelwa kwe-helical kunikeza izindawo eziningi zokuhlunga ngaphakathi kwendawo ehlangene emile. Ukuze uqhathanise amamodeli futhi ukhethe uhlobo lwe-spiral olufanele ezinhlelweni ezithile, imininingwane enemininingwane ekhasini lemikhiqizo iyinto ebalulekile yokubhekisela. Ukuqonda lezi zinto ezihlukile kuvumela abaklami bezitshalo zokucubungula ukuthi benze ukukhetha kwemishini okuhle kakhulu ezidingweni zabo eziyingqayizivele zeflowsheet.

Ama-spiral chute asebenza kahle kakhulu lapho ecubungula izinhlayiya ezisukela cishe kuma-millimitha angu-3 kuye phezulu kuma-millimitha angu-0.03, kanti isikhathi sokusebenza esihle kakhulu ngokuvamile siphakathi kuka-1.5 millimeters nama-microns angu-75. Izinhlayiya ezimakhulu ezingaphezu kwama-millimitha angu-3 zivame ukudala isiphithiphithi futhi zehlise ukusebenza kahle kokuhlukanisa, ngakho-ke ukulinganisa okufanele kokudla ngezisefo kubalulekile. Izinhlayiya ezincane kakhulu ezingaphansi kwama-microns angu-30 ngokuvamile zisingathwa kangcono ezinye izinto zomhlaba ezisebenza ngamandla adonsela phansi, nakuba amadizayini ama-spiral athuthukile andise umkhawulo wawo osebenza kahle wosayizi ophansi. Ukuba khona kobumba oluningi noma ama-slimes ekudleni kudinga ukususwa kwe-slimes ngaphambi kwe-spiral ukuze kuvinjelwe ukuphazamiseka kwe-viscosity. Yonke imodeli ye-Alicoco spiral yakhelwe ngokucophelela ngekhono lokusingatha usayizi wezinhlayiya ezithile, iqinisekisa ukusebenza kahle kwayo kokusetshenziswa okuhlosiwe. Ukubonisana nethimba lobuchwepheshe kusiza ukunquma ukuhlelwa kwe-spiral okungcono kakhulu ngokusekelwe ekusabalaliseni kwakho okuthile kosayizi wezinhlayiya zokudla.

Izinga lokubuyiswa kwe-spiral chute liyahlukahluka kuye ngokwamaminerali acutshungulwayo, izici ze-ore, kanye namapharamitha okusebenza, kodwa amasistimu aklanywe kahle ngokuvamile afinyelela amazinga okubuyiswa aphakathi kuka-85% no-95% kumaminerali okuhlosiwe anokuhluka okuhle kwensimbi. Lapho kucutshungulwa i-iron ore, isibonelo, amasekhethi e-spiral asebenzayo ngokuvamile abuyisa ngaphezu kuka-90% wamayunithi ensimbi abalulekile avela ekudleni okulungiselelwe kahle. Ukubuyiswa kwegolide nge-spiral kusekethe ye-gravity kuncike kakhulu kusayizi wokukhululwa kanye nokuba khona kwegolide elikhululekile elicolekile, ngokubuyiswa kwegolide elikhululekile elingaqinile ngokuvamile kudlula u-95%. Ukufinyelela ukubuyiswa okuphezulu kudinga ukulungiselelwa okufanele kokudla, ukukhethwa okulungile kwe-spiral, kanye nokuthuthukiswa okuqhubekayo kwamapharamitha okusebenza. Ithimba lobuchwepheshe lakwa-Alicoco lisebenza eduze namakhasimende ukuze kwandiswe ukubuyiswa ngokulungiswa kokuhlelwa kanye nezincomo zokusebenza. Izifundo eziqoshiwe zohlu zinikeza idatha ethile yokubuyiswa evela ekufakweni kwangempela, zinikeza okulindelekile okungokoqobo kwezinhlelo ezahlukahlukene.

Inombolo yamajika ku-spiral chute, ngokuvamile esukela kwamane kuya kwayisikhombisa kumamodeli ajwayelekile, inqunywa ukuqina kokwehlukanisa okudingekayo kanye nokusatshalaliswa kosayizi wezinhlayiyana zokudla. Amajika amaningi ahlinzeka ngezigaba ezengeziwe zokwehlukanisa ngaphakathi kweyunithi eyodwa, okungathuthukisa izinga le-concentrate kodwa futhi kungase kwehlise umthamo ngeyunithi ngayinye yendawo yaphansi. Ama-spiral anezindlela eziningi, lapho imigudu eyi-helical emibili noma ngaphezulu isongwa eduze kwekholomu eyodwa emaphakathi, akhulisa umthamo ngaphandle kokwandisa indawo esetshenziswayo. Ezinhlelweni zokugaya okungalungile ezinezidingo zokwehlukanisa ezilula, amajika ambalwa anganele, kuyilapho izigaba zokuhlanza zivame ukuzuza ekutholeni ama-concentrate asezingeni eliphezulu ngamajika amaningi. Uhlu lwamamodeli e-Alicoco luhlanganisa ukuhlelwa kwamajika okuhlukene ukuze kuhambisane nezinhloso ezahlukene zokucubungula. Ukukhetha okufanele kuncike ekuhlaziyweni okuphelele kohlobo lwe-ore, ikhwalithi yomkhiqizo okuhloswe ngayo, kanye nokwakhiwa kwesekethe jikelele.
