Chitsulo chosweka, monga chinyalala chomaliza chomwe chimapangidwa ndi kusungunula chitsulo, chimakhala ndi zinthu zambiri zachitsulo. Chifukwa cha kuchuluka kwake kwakukulu komanso kuchuluka kwake kwakukulu, sichingatchulidwe ndikugwiritsidwa ntchito m'makampani omanga. Chuma chamtengo wapatali sichinapezeke bwino, zomwe zimapangitsa kuti pakhale zinyalala zinazake. Chitsulo choswekacho chiyenera kubwezeretsedwanso ndikugwiritsidwanso ntchito kudzera mu njira inayake yolekanitsa maginito, ndikukwaniritsa zofunikira za mtundu wa chitsulo cha ufa chomwe chimafunikira ndi zinthu zomwe zili ndi chitsulo posungunula ng'anjo yoyaka moto, kuti chitsulo choswekacho chibwezeretsedwenso. Chingagwiritsidwe ntchito bwino pomanga.
Pakadali pano, njira inayake yolekanitsira maginito ndi njira yothandiza kwambiri, ndipo ndikofunikira kusankha zida zoyenera kuti chitsulo chilekanitse ndi kubwezeretsa bwino. Chitsulocho chimaphwanyidwa kuti chikhale chogawanika, kenako kudzera mu mpweya wouma wa maginito wolekanitsa ufa, miyala yodyetsera, kusakaniza ndi matope zimalandiridwa motsatana, ndipo chitsulo chonse chimasanthulidwa ndikusanthulidwa kuti chipeze njira yabwino kwambiri komanso magawo abwino a zida. Perekani chithandizo chaukadaulo choyenera pakupanga kwenikweni.
Katundu wa zitsulo zotayira
Chitsulo chachitsulo ndi zinyalala zomwe zimapangidwa pogwiritsa ntchito laimu wokhala ndi magnesium yambiri, laimu yogwira ntchito ndi zinthu zina zothandizira kuchotsa kuipitsidwa ndi mpweya woipa popanga zitsulo, kotero chimakhala ndi iron oxide yambiri, nthawi zambiri 20%-40%, ndipo kuchuluka kwa FeO3 kumaposa Fe2O3, yoyamba nthawi zambiri imakhala 15%-25%, pomwe yachiwiri ndi 5%-15%, zonse ziwiri zimasonyeza mphamvu ya maginito yofooka.
Zipangizo zoyesera
Zipangizo zoyeserazi zimagwiritsa ntchito FX0665 powder ore air dry magnetic separator ya Huate Company, yomwe imagwiritsidwa ntchito makamaka posankha magnetite musanaipere kapena kupanga concentrate yoyenerera kuchokera ku magnetite ya ufa.

chipolopolo chapansi
Mfundo yogwirira ntchito ya ufa wothira maginito wouma wa mpweya wa chitsulo cha ufa ikuwonetsedwa pachithunzichi. Michere imaperekedwa pamwamba pa ng'oma ya maginito kudzera pa doko lodyetsera chitsulo cha 3, ndipo mchere wa maginito umalowetsedwa pamwamba pa ng'oma ya maginito 4 pansi pa mphamvu ya maginito, ndikuzungulira ndi ng'oma ya maginito 4. Panthawiyi, mchere womwe uli pamwamba pa ng'oma ya maginito 4 umayendetsedwa ndi mphamvu ya maginito ya maginito yaikulu yozungulira ndi maginito ambiri, chipangizo choyambitsa maginito, chipangizo cholowera mpweya 6 ndi doko lochotsa fumbi 5, kotero kuti zodetsa zomwe zili mu mchere ndi zamoyo zosauka zolumikizidwa zichotsedwe bwino. Potero, kalasi ya concentrate imakula. Michere yosankhidwa ikazunguliridwa kudera losakhala maginito ndi ng'oma ya maginito 4, imawonjezeredwa ku doko lokhazikika 9 pansi pa mphamvu yokoka, mphamvu ya centrifugal ndi chipangizo chotsitsa kuti ikhale concentrate. Michere yopanda maginito kapena matupi ogwirizana osalimba amachotsedwa pakamwa pa tailings 8 chifukwa cha mphamvu yokoka ndi mphamvu ya centrifugal, ndipo amakhala tailings kapena medium ore.
Zatsopano ndi ukadaulo wofunikira wa cholekanitsa maginito cha ufa wa ore mpweya wouma
1. Chodyetsa chogwedezeka chimagwiritsidwa ntchito podyetsa, ndipo magawo a chodyetsa amatha kusinthidwa kuti akwaniritse kudyetsa kofanana;
2. Dongosolo la maginito limagwiritsa ntchito ngodya zambiri, ngodya yayikulu yokulunga (mpaka madigiri 200-260), mphamvu yayikulu (3000-6000Gs), ndipo kapangidwe ka dongosolo la maginito kamatha kusinthidwa malinga ndi momwe mchere ulili kuti ukwaniritse zizindikiro zomveka bwino za ubwino;
3. Liwiro la mzere wa silinda limasinthidwa mkati mwa 1-20m/s, ndipo liwiro loyenera la mzere lingasankhidwe malinga ndi mtundu wa miyala; silindayo imapangidwa ndi zinthu zopanda chitsulo ndipo ili ndi chipangizo chosakaniza maginito kuti chiwongolere kuchuluka kwa concentrate;
4. Ili ndi kapangidwe kake ka mpeni wopumira mpweya, chipangizo chobwezera mphepo ndi chipangizo chochotsera fumbi (magawo oyenera akhoza kusankhidwa malinga ndi mtundu ndi zofunikira za miyala); pamwamba pa silinda pali chipangizo chotulutsira zinthu, chomwe chingathe kutulutsa madzi oyera a concentrate;
Cholekanitsa maginito cha FX powder ore air dry magnetic chimapangidwa makamaka ndi chipangizo chotumizira, ng'oma yolekanitsa maginito, chipangizo chophulitsira, chipangizo chochotsera fumbi choyambitsa, chipangizo chosonkhanitsira sedimentation, ndi zina zotero. Mphamvu ya maginito ya ng'oma yolekanitsa maginito ndi 3500Gs. , mphamvu ya maginito, mphamvu yozungulira ya centrifugal, ndi zina zotero, imatha kusankha maginito a 0-5mm particle size kapena kukweza kwambiri kalasi ya magnetite ya ufa wabwino. Zotsatira zake zazikulu ndi izi:
A. Mlingo wosankhidwa wa magnetite wa 0-5mm ukhoza kuwonjezeka kuchoka pa 10% mpaka kupitirira 40%. Ungagwiritsidwe ntchito ngati kutaya musanapukute, zomwe zingathandize kwambiri mtundu woyambira ndikuwonjezera magwiridwe antchito a mphero.
B. Kalasi yosankhidwa ya -74um ndi -45um magnetite yopyapyala bwino ikhoza kuwonjezeka kuchoka pa 10% mpaka kupitirira 60%, ndipo kukhuthala koyenerera kumatha kupezeka mwachindunji mwa kusankha kouma.
Njira yoyesera ndi kusanthula.
①Kusanthula zinthu zodziwika bwino ndi kuzindikira zinthu zachitsulo.
②Kukonza ndi kuyeretsa mchere wosakhala wachitsulo monga English, long stone, fluorite, fluorite, kaolinite, bauxite, leaf sera, baryte, ndi zina zotero.
③Kupindulitsa zitsulo zakuda monga chitsulo, titaniyamu, manganese, chromium ndi vanadium.
④ Kuchulukitsa mchere wa maginito ofooka monga miyala yakuda ya tungsten, miyala ya tantalum niobium, makangaza, mpweya wamagetsi, ndi mitambo yakuda.
⑤ Kugwiritsa ntchito bwino zinthu zina monga zinthu zosiyanasiyana zotsalira ndi zinthu zosungunulira.
⑥ Pali zitsulo zachitsulo zolemera, zolemera komanso zoyandama zomwe zimaphatikizidwa ndi maginito achitsulo.
⑦Kusankha mwanzeru kwa mchere wachitsulo ndi wosakhala wachitsulo.
⑧ Mayeso osankhira mosalekeza a theka-mafakitale.
⑨ Kukonza ufa wabwino kwambiri monga kuphwanya zinthu, kugaya mipira ndi kugawa m'magulu.
⑩ Ntchito za EPC monga kuphwanya, kusankha zinthu pasadakhale, kugaya, kulekanitsa maginito (zolemera, zoyandama), kupukuta raft youma, ndi zina zotero.
