Magnetite ili ndi mphamvu ya maginito, ndipo makamaka imaphatikizapo single magnetite, vanadium-titanium magnetite, mixed ore containing magnetite and iron oxide, and ore containing magnetite polymetallic symbiosis. Magnetite imagawidwa m'magulu awiri: coarse-grained, medium-fine-grained, and micro-fine-grained kutengera kukula kwa tinthu tating'onoting'ono. Pakati pawo, chitsulo chokhala ndi tinthu tating'onoting'ono komanso tating'onoting'ono chimatha kuphwanyidwa ndikuphwanyidwa kuti chipeze chitsulo chokwanira pogwiritsa ntchito njira yofooka yolekanitsa maginito. Micro-particle embedded magnetite iyenera kuphwanyidwa bwino mpaka monomer italekanitsidwa kwathunthu, kenako kudzera mu njira zingapo zosankhidwira kuti mupeze zizindikiro zabwino zopezera phindu.
Cholekanitsa maginito cha JCTN choyeretsera ndi kuchepetsa slag chomwe chinapangidwa ndi Huate Magnet ndi cholekanitsa maginito chonyowa chomwe chinapangidwira kutsuka ndi kuyeretsa magnetite. Ndi choyenera kulekanitsa ndi kuchotsa sliming ya zinthu zodzaza ndi kupukuta ndi kugawa gawo loyamba; musanagaye gawo lachiwiri Ndipo kuchuluka kwa mchere musanasefe; kuchotsa sliming magnetite isanalowe mu sieve ndi kuchotsa sliming isanabwerere m'mbuyo; kusankha komaliza kwa magnetite, komwe kumakhala kovuta kukweza kalasi ya tinthu tating'onoting'ono ndi tinthu tating'onoting'ono mu maginito okhazikika. Mchere wachitsulo uli ndi zotsatira zomveka bwino zosonkhanitsira.
Kugwiritsa Ntchito Magnetic Separator Poyeretsa ndi Kuchepetsa Zinyalala mu Magnetite Yopyapyala
Magnetite wopyapyala kudera la Benxi ndi wa magnetite wopyapyala wa metamorphic. Mchere waukulu wachitsulo wa miyalayi ndi magnetite. Malinga ndi momwe magnetite imagwirira ntchito, kampani yathu yachita njira yoyesera yolekanitsira maginito kuti isinthe ndi kuchepetsa slag. Mayesero ndi magulu a makina amafakitale agwiritsidwa ntchito popanga mafakitale. Kugwiritsa ntchito kwenikweni kwa makina olekanitsira maginito ochepetsa slag kwayamikiridwa ndi kuvomerezedwa ndi makasitomala. Pachifukwa ichi, makina olekanitsira maginito ochepetsa slag oyeretsedwa atha kugwiritsidwa ntchito kudera la Benxi. Amalimbikitsidwa kwambiri ndipo amagwiritsidwa ntchito. Zambiri zamakampani zomwe zili patsamba lino zikuwonetsa:
1. Kugwiritsa ntchito cholekanitsa maginito pokonza ndi kuchepetsa slag ngati gawo loyamba la kulekanitsa maginito, pamene mukuonetsetsa kuti tailings grade si yoposa 1%, kukula kwa miyala yoyambirira kumawonjezeka kuchoka pa -200 mesh 80%, ndipo grade ndi pafupifupi 28% kufika pa concentrate grade ya 52%. Ndi pafupifupi 14%, cholekanitsa maginito chochepetsedwa slag sichimangowonjezera grade ya concentrate, komanso chimataya tailings zambiri, zomwe zimachepetsa kuchuluka kwa kugaya kwachiwiri ndikusunga mphamvu;
2. Cholekanitsa maginito choyeretsera ndi kuchepetsa slag chimagwiritsidwa ntchito poyeretsera, ndipo kukula kwa tinthu ta m'nthaka ndi -600 mesh 85%. Ngati index ya beneficiation ili yofanana, zitha kuzindikirika kuti cholekanitsa maginito choyeretsera chimodzi ndi slag-reduction chingalowe m'malo mwa zolekanitsa maginito zanthawi zambiri zolumikizidwa ndi mndandanda. Makinawa amasankhidwa kuti afupikitse kayendedwe ka ntchito ndikukwaniritsa cholinga chochepetsa ndalama ndikuwonjezera magwiridwe antchito.
Makhalidwe akuluakulu aukadaulo a maginito olekanitsa kuti akonzedwe bwino komanso kuchepetsa slag
■ Gwiritsani ntchito kuphatikiza kwa chipangizo chodyetsera machubu ndi malo odzaza madzi kuti mukwaniritse cholinga chodyetsa mofanana;
■ Gwiritsani ntchito mtundu watsopano wa kapangidwe kamene mtsinje wa m'madzi ndi ng'oma zimazungulira motsutsana ndi kuzungulira, zomwe zingawonjezere kuchuluka kwa mchere wobwezeretsedwa;
■ Thanki yatsopano yotsikira pansi ili ndi zotsukira za magawo ambiri komanso kapangidwe ka nsalu yotchinga madzi pamwamba, zomwe zimatha kutsuka mchere wonse pamwamba pa ng'oma;
■ Pogwiritsa ntchito makina amphamvu a magnetic angle a 240°-270° okhala ndi pole yambiri, pamodzi ndi chipangizo chogwiritsira ntchito maginito chomwe chili mu silinda, mchere umagwedezeka ndi kugwedezeka kwa maginito kangapo, ndipo madzi akamatsuka, zinthu zodetsedwa zomwe zili mu concentrate zimachotsedwa kwathunthu kuti ziwongolere kuchuluka kwa Concentrate.
■ Chipangizo chotulutsira zinthu chimagwiritsa ntchito kapangidwe kake kawiri kuti chizindikire kuchuluka kwa mchere pamene chikutulutsira zinthu.
Deta yogwiritsira ntchito ya maginito olekanitsa kuti akonzedwe bwino komanso kuchepetsa slag m'makampani
1. Cholekanitsa maginito choyeretsera ndi kuchepetsa slag chimagwiritsidwa ntchito pa gawo limodzi la kulekanitsa maginito
Pukutani chitsanzo cha miyala yamtengo wapatali kufika pa 80% ya -200 mesh, ndipo gwiritsani ntchito cholekanitsa maginito kuti muyeretsedwe bwino ndikuchepetsa slag kuti muchotse maginito pagawo loyamba.
Cholekanitsa maginito choyeretsera ndi kuchepetsa slag sichimangowonjezera kuchuluka kwa concentrate, komanso chimataya tailings zambiri, zomwe zimachepetsa kuchuluka kwa kugaya kwachiwiri ndikusunga mphamvu. Cholekanitsa maginito choyeretsera ndi kuchepetsa slag sichimangotsimikizira kuti njirayo ikuyenda bwino, komanso chimasunga ndalama.
2. Cholekanitsa maginito kuti chikhale choyeretsera ndi kuchepetsa slag chimagwiritsidwa ntchito posankha
Chifukwa cha mfundo ndi kapangidwe kake ka maginito olekanitsa zinthu kuti achepetse kutayika kwa zinthu komanso kuchepetsa kutayika kwa zinthu, amatha kuchepetsa kukulunga kwa maginito ndikuwongolera kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito, makamaka maginito opangidwa bwino.
Kugwiritsa ntchito cholekanitsa maginito pokonza ndi kuchepetsa slag kumakhudza bwino kulekanitsa kwa magnetite wopyapyala ku Benxi, Liaoning. Malo olekanitsa maginito mu gawo loyamba awonjezeka kuchoka pa 28% ya kalasi yoyambirira ya ore kufika pa 52%, zomwe ndi kuwonjezeka kwa 14%. Cholekanitsa maginito chochepetsa slag sichimangowonjezera kalasi ya concentrate, komanso chimataya tailings zambiri, chimachepetsa kuchuluka kwa kugaya kwa ore mu gawo lachiwiri, ndikusunga mphamvu; monga kusankha, kumatha kuchita ntchito yofanana yolekanitsa maginito yomwe imalowa m'malo mwa magawo awiri motsatizana. , Potero kufupikitsa kuyenda kwa njira ndikukwaniritsa cholinga chochepetsa ndalama ndikuwonjezera magwiridwe antchito.
Mapulogalamu
Kupanga kwaukadaulo kwa Huate Magneto ndiko komwe kumayambitsa chitukuko, kuyang'ana kwambiri pa kafukufuku ndi chitukuko ndi kupanga zida zapamwamba zopangira zinthu zabwino, ukadaulo wa maginito wopangira zinthu zapamwamba komanso zinthu zamagetsi zamagetsi zamakono zopulumutsa mphamvu komanso zosawononga chilengedwe. Ntchito zake zikuphatikizapo migodi, malasha, mphamvu zamagetsi, zitsulo, zitsulo zopanda chitsulo, kuteteza chilengedwe, ndi chithandizo chamankhwala. M'magawo opitilira 10, tapereka mayankho abwino kwa makasitomala opitilira 20,000 padziko lonse lapansi. Potsatira lingaliro lautumiki lakuti "Makasitomala nthawi zonse amakhala oyamba", kampaniyo ikupitilizabe kulimbikitsa kusintha kwa dongosolo lautumiki, imayesetsa kupanga ntchito zosavuta, zaumwini komanso zosinthidwa kwa makasitomala, ikutsogolera ndikulimbikitsa kusintha ndi kukweza ntchito zamafakitale, ndipo imakhala mpikisano wapadziko lonse lapansi. Opereka mautumiki a dongosolo la maginito akupitilizabe kupita patsogolo!
Kampaniyo ili ndi labotale yoyendetsera ntchito yofunika kwambiri yokonza mchere m'dziko lonse yomwe ili ndi malo okwana masikweya mita 6000, ofufuza oyeserera a nthawi zonse 120 kapena nthawi yochepa, zida zonse zoyendetsera ntchito yokonza zinthu m'ma labotale, zida zoyesera ndi kusanthula zonse, mikhalidwe yabwino yoyesera zinthu, ndi zoyeserera zosiyanasiyana. Pali zida ndi zida zoposa 200, 60% mwa izo zafika pamlingo wapamwamba kwambiri ndipo 20% mwa izo zafika pamlingo wapamwamba wapadziko lonse lapansi. Ndi chitukuko cha kupanga zida zolekanitsa maginito ngati poyambira, cholinga chachikulu chili pakupanga maginito oyendetsera zinthu ndi maginito oyendetsera zinthu m'munda waukadaulo wa zida zamaginito. Kafukufuku pa zida zazikulu zogwiritsira ntchito ukadaulo wamaginito monga makina, maginito olekanitsa okhala ndi maginito ambiri, stirrer, ndi zina zotero.
Kampani yathu ikhoza kupatsa makasitomala ndi mabungwe ofufuza njira zonse zothetsera mavuto ndi zida zoyesera zochepetsera mavuto kuyambira kuphwanya, kuwunikira, kulekanitsa kouma, kupukuta, kulekanitsa kofooka kwa maginito, kulekanitsa kwamphamvu kwa maginito, ndi zina zotero, kuti ipereke kuthekera komanga chomera chochepetsera mavuto. Malangizo otsogolera.
