Kunezinhlobo ezimbili ze umshini wokugaya iyatholakala ukuze isetshenziswe ekugayeni. Kunezinhlobo ezimbili zezigayo: izigayo zamabhola kanye nezigayo ezizimele. Ngayinye inezinzuzo nezinkinga zayo. Kubalulekile ukucabanga ukuthi iyiphi ongathanda ukuyisebenzisa.
Ama-ore ayachotshozwa futhi agxilwe kusetshenziswa i-autogenous umshini wokugaya ibholaLezi zigayo zigaya izinhlobo eziningi zamatshe ayigugu, okuhlanganisa amadayimane, igolide, iplatinum, kanye nethusi. Imithombo yokugaya emikhulu ivame ukuba yi-10% yenani eliphelele lesigayo. Lolu hlobo lwenqubo yokugaya lwandisa ukusebenza kahle kobuchwepheshe kwamanye amatshe ayigugu ngenkathi kunciphisa ukusetshenziswa kwamabhola ensimbi.
Naphezu kwezinzuzo zazo, izigayo zokugaya ezizimele zidinga amandla amaningi ukuze zichoboze ithani elilodwa lensimbi. Isizathu esiyinhloko salokhu ukuthi zidinga umphumela omkhulu wokuphakamisa. Ngaphezu kwalokho, umkhiqizo wazo uphansi uma uqhathaniswa nomkhiqizo womshini wokugaya osayizi ofanayo onebhola lensimbi.
Kwakhiwe imodeli entsha yezigayo zokugaya ezizimele ukuze kuhlolwe imiphumela yemingcele ehlukahlukene yobuchwepheshe ekusebenzeni kwesekethe. Imodeli ibikezela ukusebenza kwezinhlobo ezahlukene ze-ore ngobukhulu obuhlukahlukene bezigayo.
Ukusetshenziswa kwemishini yokugaya amashubhu ekugayeni ama-slag akuseyona into evamile. Esikhundleni salokho, kufakwa ama-VRM (ama-vertical roller mills). Anezinzuzo eziningana ngaphezu kwemishini yokugaya amashubhu.
Enye yezinzuzo eziyinhloko zokusebenzisa i-VRM yikhono lokukhiqiza ukugaya okuhle. Lokhu kungenxa yokuthi ama-VRM anezahlukanisi ezisebenza kahle kakhulu ezakhelwe ngaphakathi. Ngaphezu kwalokho, ukukhishwa kwe-calciner kunganikezwa ngqo ku-air separator.
Enye inzuzo yokusebenzisa i-VRM ukuthi ayidingi umlotha omncane we-fly ash. Umlotha we-fly ash ulula ngokwemvelo kune-slag futhi ungadlulwa yi-mill.
Ngaphezu kokusebenza kahle komshini wokugaya i-oven, izinga lokubala i-tailings lingalawulwa. Lokhu kungenxa yekhono lomshini wokugaya ukunikeza ukushisa okwanele emoyeni. Olunye uhlobo lomkhiqizo olutholakalayo yi- umshini wokugaya oqondile.
Izigayo zebhola ziyagaya, zixube, futhi zigaye izinto eziqinile zibe ngosayizi owufunayo. Ngokuvamile ziyisilinda ngesimo futhi ziza ngezinhlobo ezomile nezimanzi. Njengezinto zokugaya, izinto ezahlukahlukene ezifana ne-ceramics, i-zirconium oxide, i-zirconium nitrate, kanye ne-alumina ceramics zingasetshenziswa.
Ijubane lokujikeleza le-common amabhola okugaya zincishiswa yigiya. Kodwa-ke, intuthuko yezobuchwepheshe inike amandla amamodeli okushayela ngqo. Lokhu kwenza kube lula isivinini esisheshayo kakhulu kanye nezilinganiso zokushayela zamandla amahhashi aphezulu. Amanye amamodeli okushayela ngqo asevele esebenza, kanti amanye azolandela maduze.
Ikhono lokunikeza ukuxuba okwengeziwe kwamabhola okugaya kungenye yezinguquko ezijabulisa kakhulu zemiklamo yakamuva yokugaya. Lawa aziwa ngokuthi amasethi enduku ajikelezayo, futhi asebenza ngokukhuhla ubuso bangaphandle besikrini sokukhipha 114 ngamabhola okugaya.
Ukugaya i-closed-circuit inqubo yokudlulisa izinhlayiya eziqinile ngokuphindaphindiwe emshinini wokugaya. Lokhu kwenza izinhlayiya ezincane zihlukaniswe nomkhiqizo osikiwe kusetshenziswa isihlukanisi. Ngenxa yalokho, umkhiqizo wokugcina unokwakheka okulinganayo kwe-granulometric. Ukugaya i-closed-circuit kuthuthukisa ukonga kokugaya ngo-14% uma kuqhathaniswa nokugaya i-open circuit.
Amamodeli okugaya avaliwe ayindlela enhle kakhulu yokuhlola imiphumela yamapharamitha ahlukahlukene kanye nezimo ezizinzile. Lawa mamodeli afaka inani lezibalo ezichaza ukusatshalaliswa kosayizi, izinga lokugeleza kwe-fines, kanye nokuphuka kwezinhlayiya ezinkulu. Abacwaningi abaningana babhale amaphepha mayelana nendlela yokulingisa lezi zinqubo.
Ngaphambilini, abacwaningi babecabanga nge- umshini wokugaya elebhu izingxenye njengochungechunge lweziphehli ezixubene kahle. Encazelweni yezinhlelo zokugaya zesekethe elivaliwe, amamodeli ezibalo asanda kuthuthukiswa aqhubekela phambili nahlukene abonakale ewusizo.
I-Tencan ingumkhiqizi kuphela esitshalweni sayo esihlanganisa indawo yonke engamamitha-skwele angu-20,000 kanye nesikhungo se-R&D esinendawo yonke engamamitha-skwele angu-2,000. Lokhu kwenza i-Tencan ikwazi ukwanelisa zonke izidingo zamakhasimende ngokugcwele. I-Tencan ingumlingani nodokotela abangu-20 futhi inikezwe amalungelo obunikazi angaphezu kwama-30.
Izindawo ezintathu zebhizinisi eziyinhloko zenkampani yethu zifaka phakathi ukukhiqizwa kwemishini yempuphu, ubuchwepheshe bempuphu kanye nezinto zempuphu. Imikhiqizo yethu eyinhloko yamanje ihlanganisa zonke izinhlobo zemishini yokugaya ibhola yokusetshenziswa kwelabhorethri, imishini yokuchoboza nokugaya, imishini yokuhlola, yokuxuba nokuxuba, kanye neminye imishini yelabhorethri efana namabhokisi amagilavu, kanye neminye imishini yocwaningo lwesayensi.
Le nkampani ivunyelwe nge-ISO9001, CE, SGS kanye nezinye izitifiketi. Iphinde ibe nobuchwepheshe obungaphezu kuka-40 obunelungelo lobunikazi obuvikelwe amalungelo obunikazi obuzimele. Iqashelwa "njengebhizinisi lobuchwepheshe obuphezulu eSifundazweni saseHunan" nguhulumeni.
Amanyuvesi, izikhungo zocwaningo kanye nezinkampani ezisekelwe kubuchwepheshe yizo amakhasimende ayinhloko. Zikhonza amakhasimende angaphezu kuka-20,000 emhlabeni wonke futhi zithumela kwamanye amazwe angaphezu kuka-60.
Umnyango wokukhipha amanzi ku- umshini wokugaya ovundlile ingasetshenziswa ukulahla izinto. Uhlobo lwezinto ezingakhishwa emshinini wokugaya lunqunywa yizinto eziqunyiwe. Amatshe ayigugu, amaminerali, nezinto ezifana namatshe ziphakathi kwezinto ezigaywayo.
Umshini wokugaya ungomunye wemisebenzi yokusungula eklanyelwe ukukhiqiza izinto ezicolekile ezifana nofulawa ngezinto zokusetshenziswa. Enye indlela eklanyelwe ukukhiqiza izinto ezifana nogwadule ezinobukhulu obuphakathi. Le divayisi ihlukaniswa yisicabucabu esisekela i-grate esisha esinciphisa ukuhlanganiswa kwe-slurry.
Le divayisi yenziwe ngezinto ezithambile futhi inezimbobo eziningi zokukhipha. Imbobo ngayinye yokukhipha idizayini yenzelwe ukuvumela izinto ezicutshunguliwe ziphume esigayweni. Ingasetshenziswa futhi ukudlulisa izinto ezicoliwe zobukhulu obuthile.
