Isingeniso ku-iron ore
I-iron ore iwumthombo obalulekile wezimboni, iyi-iron oxide ore, i-mineral aggregate equkethe izakhi zensimbi noma ama-iron compounds angasetshenziswa ngokomnotho, futhi kunezinhlobo eziningi ze-iron ore. Phakathi kwazo, imikhiqizo yokuncibilikisa insimbi ifaka phakathi i-Magnetite, i-siderite, ne-hematite njalo njalo. I-iron ikhona emvelweni njenge-compound, futhi i-iron ore ingakhethwa kancane kancane ngemva kokuba i-iron ore yemvelo ichotshoziwe, igayiwe, ikhethwe ngogesi, i-flotation, futhi ikhethwe kabusha. Ngakho-ke, i-iron ore iyinto eluhlaza ebalulekile emkhakheni wokukhiqizwa kwensimbi; ngokuvamile izinga le-iron ore elingaphansi kuka-50% lidinga ukudlula ekufakweni ngaphambi kokuncibilikisa nokusetshenziswa. Njengamanje, isimo samanje semboni yensimbi ehlanganisiwe kanye nezici zemithombo yemithombo ye-iron ore yaseShayina kumele kuthuthukiswe njalo enkambisweni yokuzuza i-metallurgical ore yaseShayina ukuze kukhuthazwe intuthuko esheshayo yemboni, ukutshalwa kwezimali kwemishini emisebenzini yokuchoboza nokugaya, izindleko zokukhiqiza, ukusetshenziswa kukagesi nokusetshenziswa kwensimbi nezinye izici kuzonquma kakhulu intuthuko yemboni kanye nokusebenza kahle kwemakethe.
Ukusetshenziswa kwe-Iron ore
Izindawo eziyinhloko zokusetshenziswa kwe-iron ore yimboni yensimbi. Kulezi zinsuku, imikhiqizo yensimbi isetshenziswa kabanzi emnothweni wezwe kanye nasezimpilweni zabantu zansuku zonke, iyizinto eziyisisekelo ezidingekayo ekukhiqizweni nasekuphileni komphakathi, insimbi njengenye yezinto zokwakha ezibaluleke kakhulu emnothweni wezwe, ithatha isikhundla esibaluleke kakhulu futhi isibe yinsika ebalulekile yentuthuko yomphakathi.
Insimbi, ukukhiqizwa kwensimbi, ukuhlukahluka, ikhwalithi bekulokhu kuyisilinganiso sezimboni, ezolimo, ukuzivikela kwezwe kanye nesayensi nobuchwepheshe bezwe, uphawu olubalulekile lwezinga lentuthuko, lapho insimbi njengezinto eziyisisekelo zokusetshenziswa embonini yensimbi, iyinto ebalulekile yokusetshenziswa esekela yonke imboni yensimbi, i-iron ore idlala indima enkulu embonini yensimbi, ingancibilikiswa ibe yinsimbi yengulube, insimbi eqinisiwe, i-ferroalloy, insimbi yekhabhoni, insimbi ye-alloy, insimbi ekhethekile, i-magnetite emsulwa nayo ingasetshenziswa njengesikhuthazi se-ammonia.
Ukuze kusetshenziswe ngokugcwele izinzuzo zemithombo ye-iron ore, ngenxa yezici ze-iron ore lean, i-ore engacebile kakhulu, amaminerali ahlobene kakhulu, izingxenye ze-ore eziyinkimbinkimbi kanye nosayizi wezinhlamvu ezincane kakhulu ze-ore ore, ubuchwepheshe bokugqoka i-ore kanye nemishini yokugqoka i-ore kudingeka kuhambisane nesikhathi, singayithuthukisa kanjani ngokuphelele ikhwalithi yemikhiqizo ye-iron ore, ubuningi kanye nokusebenza kahle kwezomnotho kwamabhizinisi.
Ukugeleza kwenqubo yokugaywa kwensimbi
Ishidi lokuhlaziya izithako ze-iron ore
| IsithakoUhlobo | Iqukethe i-Fe | Iqukethe u-O | Iqukethe i-H2O |
| I-ore yensimbi ye-magnetite | 72.4% | 27.6% | 0 |
| I-Hematite iron ore | 70% | 30% | 0 |
| I-ore yensimbi ye-Limonite | 62% | 27% | 11% |
| I-ore yensimbi ye-Siderite | Isithako esiyinhloko yi-FeCO3 | ||
Uhlelo lokukhetha imodeli yomshini wokwenza impuphu yensimbi
| Imininingwane | Ukuphela komkhiqizo ocwebezelayo: 100-200mesh |
| Uhlelo lokukhetha imishini | Umshini wokugaya oqondile noma umshini wokugaya weRaymond |
Ukuhlaziywa kwamamodeli okugaya
1. I-Raymond Mill, umshini wokugaya we-pendulum ochungechunge lwe-HC: izindleko zokutshala imali eziphansi, umthamo ophezulu, ukusetshenziswa kwamandla aphansi, ukuzinza kwemishini, umsindo ophansi; iyimishini efanelekile yokucubungula i-Iron ore powder. Kodwa izinga lobukhulu obukhulu liphansi uma liqhathaniswa nomshini wokugaya oqondile.
2. Isigayo esiqondile se-HLM: imishini emikhulu, umthamo ophezulu, ukuhlangabezana nesidingo sokukhiqiza esikhulu. Umkhiqizo unezinga eliphezulu le-spherical, ikhwalithi engcono, kodwa izindleko zokutshala imali ziphakeme.
3. I-HCH ultrafine grinding roller mill: i-ultrafine grinding roller mill iyimishini yokugaya esebenza kahle, eyonga amandla, eyongayo futhi ewusizo yempuphu ye-ultrafine engaphezu kwama-meshes angu-600.
4. I-HLMX ultra-fine vertical mill: ikakhulukazi ye-ultrafine powder enamandla okukhiqiza amakhulu angaphezu kwama-meshes angu-600, noma ikhasimende elinezidingo eziphakeme ngesimo sezinhlayiya ze-powder, i-HLMX ultrafine vertical mill iyona engcono kakhulu.
Isigaba I: Ukuchotshozwa kwezinto zokusetshenziswa
Izinto ezinkulu zensimbi zichotshozwa yi-crusher kuze kube yilapho zinobuncane bokuphakelwa (15mm-50mm) obungangena emshinini wokugaya.
Isigaba II: Ukugaya
Izinto ezincane zensimbi echotshoziwe zithunyelwa endaweni yokugcina izinto nge-elevator, bese zithunyelwa ekamelweni lokugaya lesitsha ngokulinganayo nangobuningi yi-feeder ukuze zigaywe.
Isigaba III: Ukuhlukaniswa
Izinto ezigayiwe zilinganiswa ngohlelo lokulinganisa, kanti impuphu engafaneleki ilinganiswa ngohlelo lokuhlukanisa bese ibuyiselwa emshinini oyinhloko ukuze igaywe kabusha.
Isigaba V: Ukuqoqwa kwemikhiqizo eqediwe
Impuphu evumelana nobuncane igeleza ngepayipi kanye negesi bese ingena eqoqweni lokuqoqa uthuli ukuze ihlukaniswe futhi iqoqwe. Impuphu eqoqwe ithunyelwa esigungwini somkhiqizo oqediwe ngedivayisi yokudlulisa ngembobo yokukhipha, bese ipakishwa yithangi lempuphu noma i-automatic packer.
