Izikrini zokuxoxa zidlala indima ebalulekile ekusingatheni kahle isilayidi somlilo esiphathwa kahle, impahla eyinselele enokuqukethwe okuphezulu komswakama. Bahlukanisa ingxenye ye-liquid evela kwizinhlayiya eziqinile ze-slag, lula ukucubungula nokulahlwa okuqhubekayo.
Kulesi sihloko, sihlola ukubaluleka kwezikrini ezithathe izinguquko ekusingatheni, ukugqamisa izinzuzo ezinjengokusebenza okuthuthukile, izindleko zokulungisa, nezinzuzo zemvelo. Siphinde sixoxe ngezinhlobo ezahlukahlukene zezikrini zokuxoxa, kufaka phakathi izikrini zokudlidliza, izikrini ezijikelezayo, kanye nemishini yebhande, kanye nezicelo zazo ezithile embonini ye-slag. Ngokuqonda izici zabo, amabhizinisi angenza izinqumo ezinolwazi futhi asebenzise izinqubo zawo zokuphatha.
Indima yezikrini ezitholwayo esithandweni sokuphamba isilayidi
Izikrini zokuxoxa zidlala indima ebalulekile ekusingatheni kahle kwesilayi somlilo, ukuvela kwemboni ebabayo. Lo mbhalo uhlose ukuhlola ukubaluleka kwezikrini ezilandelanayo kule nqubo futhi ukhanyisela ngezinzuzo zazo.
Isilayidi somlilo, esaziwa nangokuthi yi-slag yensimbi, insali ebilisiwe ekhiqizwa lapho i-iron ore ithambekele ukukhiqiza insimbi. Ngenxa yokusetshenziswa kwendlela yokuhlukaniswa okumanzi kwinqubo yokuhlunga ye-slag, okuqukethwe umswakama wemisila kuphezulu.Lokhu yilapho izikrini zokuxoxa zizodlalwa khona.
Izikrini zokuxoxa, njengoba igama libonisa, zenzelwe ukususa umswakama owengeziwe ezintweni zokwenziwa, ukuzenza kube lula ukuphatha nokuhamba. Endabeni yesilayidi somlilo, izikrini ezikhuthazayo zihlukanisa ngempumelelo isigaba se-liquid esigabeni esiqinile, okuholele kumkhiqizo omile nokwengeziwe.
Enye yezinzuzo ezisemqoka zokusebenzisa izikrini ezikhuthazayo e-Furace Slag Handling ukuncishiswa kokuqukethwe komswakama. Ngokususa amanzi amaningi, isisindo se-slag sincishiswe kakhulu, okwenza kube lula futhi kubiza kakhulu ukuthutha. I-Slag Emisiwe futhi inciphisa ubungozi bokuchitheka futhi ithuthukise ukuphepha okuphelele ngesikhathi sokuphatha nokulahlwa.
Ngaphezu kwalokho, Izikrini zokuxoxa zineqhaza ekusimeni kwemvelo kwemboni yensimbi. Ngokususa kahle umswakama ovela esithandweni somlilo, izikrini zinika amandla ukululama nokusebenzisa kabusha ngezinto ezibalulekile. Lokhu akugcini nje ngokunciphisa imfucuza kepha futhi kugcina izinsiza zemvelo futhi kunciphisa i-carbon footprint ehlotshaniswa nokukhiqizwa kwensimbi.
Ngaphezu kwamakhono abo okususa umswakama, izikrini ezikhuthazayo nazo zisiza ekuhlukanisweni nasekwahlukanisweni kwamasayizi ahlukene wezinhlayiya ngaphakathi kwe-slag. Lokhu kubaluleke kakhulu ekufezeni umkhiqizo ongaguquguquki futhi ofanayo. Izikrini zisusa ngempumelelo izinhlayiya eziqine, ziqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nokucaciswa okufunayo.
Ukwenza kahle ukusebenza kwezikrini ezithathe ama-vounting esithandweni somlilo esithandweni, ukulungiswa njalo nokuqapha kubalulekile. Lokhu kufaka phakathi ukuhlanza izikrini ukuvikela ama-blockages kanye nokuqinisekisa ukuqondanisa okufanele kanye nokungenisa intshiseko kwamaphaneli wesikrini. Ngokwenza kanjalo, izikrini zingasebenza ngokusebenza kwazo okuphezulu, okuholele ekukhiqizweni okuthuthukile kanye nokonga izindleko.
Izinhlobo zezikrini zokuxoxa ze-Dewanting for Isithambisi Sokusingatha
Izikrini zokuxoxa zidlala indima ebalulekile ekusingatheni isilayidi somlilo, ukuvela kwenqubo yensimbi yensimbi. Lezi zikrini zenzelwe ngokukhethekile ukuhlukanisa ama-solid kusuka kuketshezi, ukuqinisekisa ukusebenza kahle nokusebenza ngempumelelo. Kunezinhlobo ezahlukene zezikrini ezitholwayo ezitholakala emakethe, okunikelwa ngakunye okunikeza izici ezihlukile nezinzuzo.
Uhlobo olulodwa lwesikrini esiguqukayo esisetshenziselwa ukuphatha isithando somlilo yisikrini sokudlidliza. Lesi sikrini sisebenzisa ukudlidliza okuthe xaxa ukuhlukanisa amanzi kusuka ku-slag, okuvumela ukufundwa okulula futhi okusebenzayo. Ukunyakaza okudlidliza kusiza ukukhulisa ijubane lapho amanzi akhipha khona i-slag, enciphisa kakhulu okuqukethwe umswakama. Lolu hlobo lwesikrini lusebenza kahle kakhulu ekususeni amanzi amaningi kanye nokwenza ngcono ukuphathwa kwesilayidi somlilo.
Olunye uhlobo lwesikrini esiguqukayo esisetshenziswa kabanzi ku-Slag Handling yisikrini se-Centrifugal Dewanting Screen. Lesi sikrini sisebenzisa amandla e-centrifugal ukuhlukanisa uketshezi kusuka kuma-solids. Ukujikeleza okujikelezayo kwesikrini kwakha umphumela we-centrifugal, kucindezela amanzi abheke emaphethelweni angaphandle ngenkathi ama-solids ebheke enkabeni. Le nqubo yokwehlukanisa iqinisekisa ukusebenza kahle okuthe xaxa futhi isiza ekunciphiseni okuqukethwe umswakama we-slag.
Ngaphezu kwalezi zinhlobo, kukhona nezikrini eziguqukayo ze-vacuum ezivame ukusetshenziselwa ukuphatha isithando somlilo. Lezi zikrini zisebenzisa uhlelo lwe-vacuum ukususa amanzi kwi-slag. I-vacuum idala amandla okumunca adonsela amanzi esikrinini, ashiye ama-solids angemuva. Le ndlela yokuxoshwa ethonyayo isebenza ngempumelelo futhi iqinisekisa ukususwa okugcwele komswakama kusuka ku-slag.
Ukugcina
Izikrini zokuxoxa zibalulekile embonini yensimbi yokusingathwa kwesilayidi somlilo. Lezi zikrini zisusa umswakama ngokweqile, zihlukanise izinhlayiya, futhi zithuthukise ukuhanjiswa kwe-slag. Izinzuzo zabo zifaka isandla ekusebenzeni kahle, kokusimama kanye nempumelelo yomkhakha wensimbi.
Ngokukhetha uhlobo olufanele lwesikrini sokuxoxa, abakhiqizi bensimbi bangathuthukisa ukusebenza kokulawulwa kweSlag, banciphise okuqukethwe komswakama, futhi bakhuphule ukukhiqiza kwesikhungo. Noma ngabe kuyisikrini sokudlidliza, centrifugal, noma i-vacuum dewamemer screen, la madivaysi abonakalisa njengempahla ebalulekile embonini yensimbi.
