Isingeniso ku-ore ye-aluminium
I-aluminium ore ingakhishwa ngokwezomnotho nge-aluminium ore yemvelo, i-bauxite iyona ebaluleke kakhulu. I-Alumina bauxite yaziwa nangokuthi i-bauxite, ingxenye eyinhloko yi-alumina oxide eyi-hydrated alumina equkethe ukungcola, iyiminerali yomhlabathi; emhlophe noma empunga, ibonakala ngombala onsundu ophuzi noma opinki ngenxa yensimbi equkethwe kuyo. Ubuningi bungu-3.9 ~ 4g/cm3, ubulukhuni bungu-1-3, abubonakali futhi buthambile; abuncibiliki emanzini, buncibilika ku-sulfuric acid kanye nesisombululo se-sodium hydroxide.
Ukusetshenziswa kwe-ore ye-aluminium
I-Bauxite icebile ngezinsizakusebenza, edingekayo ezimbonini eziningi; ngakho-ke, iyinto ethandwa kakhulu engeyona eyensimbi, futhi yingakho iye yamukelwa kabanzi, ikakhulukazi ngoba iyathembisa kakhulu emkhakheni wezimboni.
1. Imboni ye-aluminium. I-bauxite esetshenziswa embonini yezokuvikela kazwelonke, yezindiza, yezimoto, kagesi, yamakhemikhali kanye neminye imikhakha yezidingo zansuku zonke.
2. Ukuthunga. I-bauxite ene-calcined icutshungulwa ibe yimpuphu ecolekile yokuthungwa ngemva kwesikhunta futhi isetshenziswa kwezempi, ezindiza, kwezokuxhumana, kwezinsimbi, kwemishini kanye nakwemishini yezokwelapha.
3. Ngemikhiqizo ephikisayo. Ukungavumelani kwe-bauxite ene-calcium ephezulu kungafinyelela ku-1780 °C, ukuqina kwamakhemikhali, kanye nezakhiwo ezinhle zomzimba.
4. Imicu ye-aluminosilicate refractory. Inezinzuzo eziningana ezifana nesisindo esincane, ukumelana nokushisa okuphezulu, ukuzinza okuhle kokushisa, ukuhanjiswa kokushisa okuphansi, amandla amancane okushisa kanye nokumelana nokudlidliza komshini njalo njalo. Ingasetshenziswa ensimbini nasensimbini, ekusetshenzisweni kwensimbi okungeyona i-ferrous, kuma-elekthronikhi, kuphethiloli, kumakhemikhali, ezindizayo, enuzini, ekuvikeleni kwezwe nakwezinye izimboni.
5. Izinto ezingavuthiwe ze-magnesia ne-bauxite, ezifakwe nge-binder efanele, zingasetshenziswa ekubunjweni kwe-cylinder liner iyonke nge-ladle yensimbi encibilikisiwe ngemiphumela emihle kakhulu.
6. Ukukhiqizwa kwesimende se-bauxite, izinto ezihudulayo, nezinto ezahlukahlukene ezihlanganisiwe kungenziwa nge-aluminium bauxite embonini ye-ceramic kanye nemboni yamakhemikhali.
Ukugeleza kwenqubo yokuchithwa kwe-ore ye-Aluminium
Ishidi lokuhlaziya izithako ze-aluminium ore
| I-Al2O3,SiO2,Fe2O3,TiO2,H2O＋ | S、CaO、MgO、K2O、Na2O、CO2、MnO2、Izinto eziphilayo、Carbonaceous njll. | Ga,Ge,Nb,Ta,TR,Co,Zr,V,P,Cr,Ni njll |
| Ngaphezulu kuka-95% | Izithako zesibili | Izithako zokulandelela |
Uhlelo lokukhetha imodeli yomshini wokwenza i-aluminium ore powder
| Imininingwane | Ukucutshungulwa okujulile kwempuphu ecolekile (200-400mesh) |
| Uhlelo lokukhetha imishini | Umshini wokugaya oqondile kanye nomshini wokugaya weRaymond |
Ukuhlaziywa kwamamodeli okugaya
1. I-Raymond Mill, umshini wokugaya we-pendulum ochungechunge lwe-HC: izindleko zokutshala imali eziphansi, umthamo ophezulu, ukusetshenziswa kwamandla okuphansi, ukuzinza kwemishini, umsindo ophansi; iyimishini efanelekile yokucubungula i-aluminium ore powder. Kodwa izinga lobukhulu obukhulu liphansi uma liqhathaniswa nomshini wokugaya oqondile.
2. I-HLM vertical mill: imishini emikhulu, umthamo ophezulu, ukuhlangabezana nesidingo sokukhiqiza esikhulu. Umkhiqizo unezinga eliphezulu le-spherical, ikhwalithi engcono, kodwa izindleko zokutshala imali ziphakeme.
Isigaba I: Ukuchotshozwa kwezinto zokusetshenziswa
Izinto ezinkulu ze-aluminium ore zichotshozwa yi-crusher kuze kube yilapho zinobuncane bokuphakela (15mm-50mm) obungangena emshinini wokugaya.
Isigaba II: Ukugaya
Izinto ezincane ze-aluminium ore ezichotshoziwe 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.
Izibonelo zokusetshenziswa kokucubungula i-aluminium ore powder
Imodeli nenombolo yale mishini: Isethi eyi-1 ye-HC1300
Ukucubungula izinto zokusetshenziswa: i-Bauxite
Ubunono: 325 mesh D97
Umthamo: 8-10t / h
Ukucushwa kwemishini: Isethi eyi-1 ye-HC1300
Ukuze kukhiqizwe impuphu enencazelo efanayo, umkhiqizo we-HC1300 uphakeme cishe ngamathani ama-2 kunowomshini wendabuko we-5R, futhi ukusetshenziswa kwamandla kuphansi. Lonke uhlelo luzenzakalelayo ngokuphelele. Izisebenzi zidinga kuphela ukusebenza egumbini lokulawula eliphakathi. Ukusebenza kulula futhi konga izindleko zabasebenzi. Uma izindleko zokusebenza ziphansi, imikhiqizo izoncintisana. Ngaphezu kwalokho, yonke idizayini, isiqondiso sokufaka kanye nokuqaliswa komsebenzi wonke kumahhala, futhi sanelisekile kakhulu.
