Izikhukhula ze-rotary kiln zisetshenziswa kakhulu ukuze zisebenze ngokushisa ama-ore e-copper sulfide ngenxa yezinzuzo zazo eziningi ekufinyeleleni emsebenzini ophumelelayo futhi ophathwayo wento ethile yokushisa ephakeme edingekayo ezinjeni ze-metalurgical. Nansi imishwana emikhulu yokusetshenziswa kwezikhukhula ze-rotary kiln kulolu hlelo:
Izikulu ze-rotary zisebenza ezingeni lokushisa eliphakeme, ngokuvamile phakathi kuka-800°C no-1200°C, okubalulekile ekuguquleni imithi ye-copper sulfide (isb. i-copper pyrites, i-bornite) ibe ama-oxide e-copper. Lezi zikulu zivumela ukulawulwa ngok 정확한 kwezinga lokushisa kanye nokwabelana ngokulinganayo kokushisa, kuqinisekisa ukuphenduka okuhambisanayo nokwakheka okufanele komkhiqizo ophumelele.
Amakilni e-rotary aklanyelwe ukwandisa ukusebenza kokushisa, kancane kancane kunciphisa ukusetshenziswa kwefuyudu ngesikhathi sokucashunwa. Ukushisa kudluliselwa kahle ku-ore ngokuxhumana ngqo nasekukhanyeni. Amakilni e-rotary wesimanjemanje nawo afaka izindawo zokushisa ngaphambi okuphumela phezulu ezithola futhi zisebenzise ukushisa okuphuma, okulwenza le nqubo ibe nephephe kakhulu.
Ngokwehlukana nezinqubo zebhatchi, ama-kilns aphindayo avumela ukucubungula okuqhubekayo, okwenza kube kufanelekile ukuphatha amasimu amakhulu e-copper sulfide ore. Le scalabiliti ibalulekile ekufezekiseni izidingo zokusebenza kwezimboni nasekuthuthukiseni ukusebenza kahle.
Izithando ze-rotary ziyakwazi ukujwayela futhi zingamukela umehluko wezinsimbi. Zingasebenza ngezinsimbi ezinezakhiwo ezihlukahlukene, osayizi bamabhamuza ahlukile, kanye nomswakama. Zingaphinde zenziwa ngesimo esihlukile, njengezinhlelo zokufaka igesi, ukuze zihlale ziwusizo ezifanele zokucubungula.
Ngesikhathi sokukhalipha kwesithako se-copper sulfide, izikhalazo ezinjenge-rotondi zenza kube lula ukuxhumana phakathi kwesithako namagwayi okoksizayo. Lokhu kusiza ekuguqulweni kwe-sulfides kube ama-oxides ngesikhathi sithutha i-gas ye-sulfur dioxide, engathathwa ukuze iqhubeke nokucubungula noma ukuhambisana nemvelo.
Ukuhamba okujikelezayo kwekilni kuqinisekisa ukujolwa okuqhubekayo nokuhlanganiswa kokwakhiwa, kubonisa wonke umugqa wesihlabathi emathinini nasegazini yokushisa. Lokhu kukhulisa inqubo ye-calcination futhi kuvimba ukuhlanganiswa noma ukushisa okungalingani.
Ama-rotary kiln avamise ukuhlinzekwa ngezinhlelo zokukhipha ezikwazi ukubamba nokucubungula gazi le-sulfur dioxide (SO2) elikhishwa ngesikhathi sokwakheka. I-SO2 ingasetshenziselwa ukukhiqiza i-sulfuric acid, okungeza inani lezomnotho futhi kuxazulule ukukhathazeka kwemvelo.
Izinhlelo ze-rotary kiln ziqinile futhi zingabekezelela izinga lokushisa eliphakeme nemvelo yokProcessing eqinile, okwenza zifanele ukusetshenziswa isikhathi eside eku-calcining izinsimbi ze-copper sulfide.
IziFuduzo ze-rotary kiln zihlala zinikeza isixazululo esithembekile nesisebenza kahle sokukhuhlaza izinsimbi zesiliva, zinikeza uhlelo olukhululekile, olukhulukazi, ukusebenza kahle kokushisa, kanye nezinzuzo ezilungile. Ukuba nekhono lokukhiqiza izinto zokwakha eziphakeme kakhulu ngezilinganiso ezinkulu kuyilapho sithobela imithetho yokulawulwa kokungcoliswa, kwenza zibe ithuluzi elibalulekile embonini yensimbi.
I-Shanghai Zenith Mineral Co., Ltd. iyinkampani ehamba phambili yokukhiqiza imishini yokuphuca nokugaya eChina. Ngaphezu kweminyaka engama-30 yokuhlangenwe nakho embonini yemishini yokumba, i-Zenith yakhile idumela eliqinile lokuhlinzeka ngama-crusher, ama-mill, imishini yokwenza uthuli, kanye nemishini yokucubungula imithombo yezinsiza yekhwalithi ephezulu kumakhasimende emhlabeni jikelele.
Ibhange elisemqoka eShanghai, eShayina, i-Zenith ihlanganisa ucwaningo, ukukhiqiza, ukuthengisa, kanye nezinsizakalo, inikeza izixazululo ezigcwele kwezokuhlanganisa, ukuthengwa kwemikhiqizo, kanye nezimboni zokushisela imayini. Imishini yayo isetshenziswa kakhulu emkhakheni wezokwakha, ezokwakha, ubunjiniyela bokhemikhali, kanye nokuvikela imvelo.
Umgomo ukuyekethisa ekwakheni izinto ezintsha nokwaneliseka kwamakhasimende, iShanghai Zenith iqhubeka nokuthuthuka kwezokukhiqiza okuhlakaniphile nokukhiqiza okuluhlaza, ikunikeza imishini ethembekile kanye nezinsizakalo eziphelele zokuthengisa emva kokuthengisa ukusiza amaklayenti afinyelele ezinhlelweni ezisebenzayo nezizinzile.
