Chiyambi cha miyala ya aluminiyamu
Miyala ya aluminiyamu imatha kuchotsedwa m'njira yachilengedwe ya aluminiyamu, bauxite ndiyo yofunika kwambiri. Alumina bauxite imadziwikanso kuti bauxite, gawo lalikulu ndi alumina oxide yomwe ndi alumina yosungunuka yokhala ndi zinthu zosafunika, ndi mchere wa nthaka; woyera kapena imvi, imawoneka ngati yachikasu kapena pinki chifukwa cha chitsulo chomwe chilimo. Kuchuluka kwake ndi 3.9 ~ 4g/cm3, kuuma 1-3, kosawoneka bwino komanso kofooka; kosasungunuka m'madzi, kusungunuka mu sulfuric acid ndi sodium hydroxide solution.
Kugwiritsa ntchito miyala ya Aluminiyamu
Bauxite ili ndi zinthu zambiri zofunikira, zomwe zimafunika m'mafakitale ambiri; chifukwa chake, ndi chinthu chodziwika bwino chosakhala chachitsulo, ndipo chifukwa chake chalandiridwa kwambiri, makamaka chifukwa ndi chodalirika kwambiri m'mafakitale.
1. Makampani opanga aluminiyamu. Bauxite imagwiritsidwa ntchito pa ntchito zoteteza dziko, ndege, magalimoto, zamagetsi, mankhwala ndi mafakitale ena ofunikira tsiku ndi tsiku.
2. Kuponya. Calcined bauxite imakonzedwa kukhala ufa wosalala woti igwiritsidwe ntchito pambuyo pa nkhungu ndipo imagwiritsidwa ntchito m'magulu ankhondo, ndege, kulumikizana, zida, makina ndi zida zamankhwala.
3. Pa zinthu zotsutsana ndi calcium. Kukana kwa bauxite yokhala ndi calcium yambiri kumatha kufika 1780 °C, kukhazikika kwa mankhwala, komanso kukhala ndi makhalidwe abwino.
4. Ulusi wofewa wa aluminosilicate. Uli ndi ubwino wambiri monga kulemera kopepuka, kukana kutentha kwambiri, kukhazikika bwino kwa kutentha, kutentha kochepa, kutentha pang'ono komanso kukana kugwedezeka kwa makina ndi zina zotero. Ungagwiritsidwe ntchito mu chitsulo ndi chitsulo, zitsulo zopanda chitsulo, zamagetsi, mafuta, mankhwala, ndege, nyukiliya, chitetezo cha dziko ndi mafakitale ena.
5. Zipangizo zopangira magnesia ndi bauxite, zowonjezeredwa ndi chomangira choyenera, zingagwiritsidwe ntchito popanga chidebe chachitsulo chosungunuka ndi zotsalira zabwino kwambiri.
6. Kupanga simenti ya bauxite, zinthu zokwawa, ndi mankhwala osiyanasiyana kungapangidwe ndi aluminiyamu bauxite m'makampani opanga zinthu zadothi komanso makampani opanga mankhwala.
Kuyenda kwa njira ya kupukutira kwa aluminiyamu
Pepala losanthula zinthu zopangidwa ndi aluminiyamu
| Al2O3,SiO2,Fe2O3,TiO2,H2O＋ | S、CaO、MgO、K2O、Na2O、CO2、MnO2、Organic matter、Carbonaceous etc | Ga,Ge,Nb,Ta,TR,Co,Zr,V,P,Cr,Ni etc |
| Kuposa 95% | Zosakaniza zina | Zosakaniza zotsalira |
Pulogalamu yosankhira chitsanzo cha makina opangira ufa wa aluminiyamu
| Kufotokozera | Kukonza ufa wabwino kwambiri (200-400mesh) |
| Pulogalamu yosankha zida | Mphero yopukutira yowongoka ndi Mphero yopukutira ya Raymond |
Kusanthula kwa mitundu ya mphero yopera
1. Raymond Mill, HC series pendulum grinding mill: ndalama zochepa zogulira, mphamvu zambiri, kugwiritsa ntchito mphamvu zochepa, kukhazikika kwa zida, phokoso lochepa; ndi zida zoyenera kwambiri pokonza ufa wa aluminiyamu. Koma kuchuluka kwa grinding mill ndi kochepa poyerekeza ndi grinding mill.
2. HLM vertical mill: zida zazikulu, zogwira ntchito kwambiri, kuti zikwaniritse kufunikira kwakukulu kwa kupanga. Chogulitsacho chili ndi mulingo wapamwamba wozungulira, wabwino kwambiri, koma mtengo wogulira ndi wokwera.
Gawo Loyamba: Kuphwanya zipangizo zopangira
Chitsulo chachikulu cha Aluminium chimaphwanyidwa ndi chotsukira mpaka kufika pamlingo wochepa (15mm-50mm) womwe ungalowe mu mphero yopera.
Gawo Lachiwiri: Kupera
Zipangizo zazing'ono zopangidwa ndi aluminiyamu zophwanyika zimatumizidwa ku hopper yosungiramo zinthu ndi elevator, kenako zimatumizidwa ku chipinda chopukusira cha mphero mofanana komanso mochuluka ndi chodyetsa kuti chipukute.
Gawo Lachitatu: Kugawa
Zipangizo zophwanyidwa zimayesedwa ndi dongosolo lowunikira, ndipo ufa wosayenerera umayesedwa ndi chogawa ndikubwezedwa ku makina akuluakulu kuti uperedwenso.
Gawo V: Kusonkhanitsa zinthu zomalizidwa
Ufa wofanana ndi kupyapyala umadutsa mu payipi pamodzi ndi mpweya ndipo umalowa mu chosonkhanitsira fumbi kuti ulekanitsidwe ndi kutengedwa. Ufa womalizidwa wosonkhanitsidwa umatumizidwa ku silo ya chinthu chomalizidwa ndi chipangizo chonyamulira kudzera mu doko lotulutsira, kenako nkupachikidwa ndi chosungira ufa kapena chopakira chokha.
Zitsanzo zogwiritsira ntchito ufa wa aluminiyamu
Chitsanzo ndi chiwerengero cha zida izi: seti imodzi ya HC1300
Kukonza zopangira: Bauxite
Kusalala: 325 mesh D97
Mphamvu: 8-10t / h
Kapangidwe ka zida: seti imodzi ya HC1300
Pakupanga ufa wokhala ndi mawonekedwe omwewo, mphamvu ya HC1300 ndi yokwera pafupifupi matani awiri kuposa ya makina achikhalidwe a 5R, ndipo mphamvu zomwe zimagwiritsidwa ntchito ndizochepa. Dongosolo lonse limagwira ntchito yokha. Ogwira ntchito amangofunika kugwira ntchito mchipinda chowongolera chapakati. Ntchitoyi ndi yosavuta ndipo imasunga ndalama zogwirira ntchito. Ngati ndalama zogwirira ntchito zili zochepa, zinthuzo zidzakhala zopikisana. Kuphatikiza apo, kapangidwe konse, malangizo oyika ndi kuyimitsa ntchito yonse ndi zaulere, ndipo takhutira kwambiri.
