Txij li xyoo 1990, cov teb chaws txawv teb chaws tau pib kawm txog kev siv tshuab ua kom zoo thiab tau ua qee qhov kev tshawb pom theoretical, xws li GunsonSortex hauv UK thiab Outo-kumpu hauv Finland. thiab RTZOreSorters, thiab lwm yam, tau tsim thiab tsim ntau dua kaum hom kev lag luam photoelectric sorters, radioactive sorters, thiab lwm yam, thiab tau ua tiav hauv kev sib cais cov hlau tsis yog ferrous thiab cov hlau muaj nqis, tab sis vim yog tus nqi siab, kev sib cais qis, Lub peev xwm ua tiav yog me me, thiab nws txwv hauv kev txhawb nqa thiab daim ntawv thov.
Piv nrog rau cov teb chaws txawv teb chaws, kev tshawb fawb txog thev naus laus zis hauv kuv lub teb chaws pib lig heev, thiab thaj chaw tshawb fawb kuj nqaim heev. Nyob ib ncig ntawm xyoo 2000, qee lub tshuab cais tawm kuj tau tshwm sim hauv kev lag luam hauv tsev, feem ntau yog kev cais xim, kev cais infrared, kev cais hluav taws xob, thiab lwm yam, feem ntau yog siv rau kev cais cov nplej, khoom noj, tshuaj yej, tshuaj, cov khoom siv tshuaj lom neeg, ntawv, iav, kev cais pov tseg thiab lwm yam lag luam, tab sis rau cov hlau muaj nqis thiab tsis tshua muaj xws li kub, av tsis tshua muaj, tooj liab, tungsten, thee, hlau tsis muaj zog, thiab lwm yam tsis tuaj yeem xaiv ua ntej thiab pov tseg ua ntej, tshwj xeeb tshaj yog nyob rau hauv qhuav ntse ua ntej xaiv cov khoom siv pov tseg tseem dawb paug.
Tam sim no, cov chaw tsuas hauv tsev tsis muaj cov khoom siv tshwj xeeb zoo rau kev pov tseg ua ntej ntawm cov hlau nplaum tsis muaj zog, cov hlau tsis muaj hlau, thiab lwm yam, feem ntau yog siv txoj kev cais thawj zaug thiab txoj kev sib cais hlau nplaum, thiab qhov loj me ntawm cov khoom sib cais feem ntau yog nruab nrab ntawm 20 thiab 150 hli. Lub zog siab thiab tus nqi siab. Rau cov zaub mov uas muaj qhov sib txawv me me ntawm cov xim zoo li cas, ci ntsa iab, cov duab, thiab qhov ceev ntawm cov hlau thiab cov pob zeb pov tseg, qhov kev ua haujlwm cais tsawg, qhov yuam kev loj, thiab qee qhov tsis tuaj yeem paub qhov txawv. Rau magnetite, txoj kev sib cais hlau nplaum tuaj yeem siv los pov cov tails, tab sis rau cov hlau uas muaj cov khoom sib nqus tsis muaj zog, cov hlau tsis muaj hlau, thiab lwm yam, qhov yuam kev sib cais loj, qhov ua haujlwm sib cais tsawg, thiab muaj kev pov tseg loj ntawm cov peev txheej.
Lub tshuab ntsuas ntse ntse no tsim nyog rau kev kho ua ntej ntawm cov hlau nrog qhov siab dilution ntawm cov hlau nyoos thiab kev sib cais zoo ntawm cov pob zeb ib puag ncig thiab cov hlau muaj txiaj ntsig tom qab tsoo.
01
Txo qhov qib txiav tawm ntawm cov chaw tsuas yog sib npaug rau kev nthuav dav cov khoom lag luam ntawm cov hlau;
02
Txo tus nqi ntawm kev sib tsoo thiab kev pab cuam tom qab;
03
Lub peev xwm ua tiav ntawm lub kaw lus tuaj yeem txhim kho tau raws li qhov xwm txheej uas cov khoom siv sib tsoo qub tseem tsis hloov pauv;
04
Kev txhim kho qib xaiv yog qhov zoo rau kev ruaj khov thiab txhim kho qhov zoo ntawm cov concentrates thiab txo cov nqi smelting;
05
Txo cov khoom ntawm cov tailings zoo, txo cov nqi tsim khoom thiab kev saib xyuas ntawm cov pas dej tailings, thiab txhim kho qhov kev nyab xeeb nyob ib puag ncig thaj chaw pas dej.
Piv txwv li, cov chaw kub hauv kuv lub teb chaws muaj cov peev txheej kub pov thawj: tam sim no, kuv lub teb chaws muaj cov peev txheej kub pov thawj yog 15,000-20,000 tons, qeb thib xya hauv ntiaj teb, nrog rau cov khoom tsim tawm kub txhua xyoo ntau dua 360 tons, cov chaw khaws cia kub pob zeb suav txog li 60%, thiab qib tso nyiaj ore nruab nrab ntawm kwv yees li 5%. Txog g / t, cov chaw khaws cia kub pob zeb yog li 3 billion tons. Tau dhau los ua tus tsim kub loj tshaj plaws hauv ntiaj teb. Txawm li cas los xij, cov txheej txheem ua kom kub zoo hauv kuv lub teb chaws tseem siv cov txheej txheem flotation-concentrate cyanidation ib txwm muaj. Tsis muaj txoj hauv kev zoo los pov cov tails ua ntej kev sib tsoo thiab sib tsoo. Lub luag haujlwm ntawm kev sib tsoo, sib tsoo thiab flotation yog loj, thiab tus nqi ntawm kev ua kom zoo tseem siab. Tus nqi poob ntawm kev khawb av yog ntau dua 5%, tus nqi rov qab ntawm kev ua kom zoo thiab smelting yog li 90%, tus nqi ua kom zoo siab yog siab, tus nqi rov qab cov peev txheej qis, thiab kev tiv thaiv ib puag ncig tsis zoo.
Tom qab muab pov tseg ua ntej los ntawm kev txheeb xyuas lub sensor ntse, cov pob zeb pov tseg uas xaiv tau tuaj yeem suav txog 50-80% ntawm cov hlau nyoos uas xaiv, ua rau cov qib kub uas xaiv tau nplua nuj los ntawm 3-5 zaug, thiab txo cov neeg ua haujlwm hauv lub Hoobkas hnav khaub ncaws los ntawm 15-20%, nce 25-30% ntawm cov pob zeb pov tseg thiab 10-15% ntawm kev tsim hlau.
Tus nqi ntawm kev sib tsoo thiab kev sib tsoo tuaj yeem txuag tau ntau dua 50%, qhov ntim tshuaj lom neeg tom qab tuaj yeem txo tau ntau dua 50%, kev ua haujlwm zoo dua qub, tus nqi rov siv dua ntawm cov pob zeb pov tseg tau zoo dua, kev puas tsuaj rau ib puag ncig tau txo qis, thiab cov txiaj ntsig kev lag luam tau zoo dua.
Qhov ntau thiab tsawg ntawm cov khoom me me ntawm kev ntsuas ntse sensor tuaj yeem ncav cuag li 1 hli txog 300 hli, thiab lub sensor tuaj yeem txheeb xyuas txog li 40,000 daim hlau ib ob. Nws tsuas yog siv ob peb ms rau txhua daim hlau los ntawm kev kuaj pom ntawm lub sensor tau txais mus rau cov lus qhia kev cais tawm uas tau txais los ntawm tus actuator. Nws tsuas yog siv ob peb ms rau lub module txhaj tshuaj kom ua tiav ib qho kev ua tiav. Lub peev xwm ua tiav siab tshaj plaws ntawm ib lub tshuab tuaj yeem ncav cuag 400 t / h, thiab lub peev xwm ua tiav ntawm ib lub cuab yeej tuaj yeem ncav cuag 3 lab tons hauv ib xyoos, uas yog sib npaug rau qhov ntsuas ntawm qhov nruab nrab thiab loj mine.
Cov khoom siv ntsuas ntse ntse tuaj yeem hloov kho software thiab preset sorting thresholds online, thiab teb rau qhov hloov pauv ntawm qhov zoo thiab ntau ntawm cov hlau nyoos hauv lub sijhawm, uas tsis tuaj yeem ua tiav ntawm cov khoom siv ntsuas ib txwm muaj. Tsuav yog cov hlau nyoos mus txog qee qib ntawm kev sib cais hauv theem crushing, txawm tias nws tsuas yog qhov degree dissociation ntawm pob zeb lossis gangue nyob ib puag ncig, lossis qhov kawg concentrate yog ncaj qha tsim, nws feem ntau yog siv rau ntau yam hlau ores (non-magnetic lossis weakly magnetic hlau ore, tooj liab, txhuas, Pre-xaiv thiab pov tseg ntawm zinc, nickel, tungsten, molybdenum, tin, rare earth, kub, thiab lwm yam), thee thiab cov zaub mov tsis yog hlau xws li talc, fluorite, calcium carbonate, dolomite, calcite, apatite, thiab lwm yam. Tus nqi ntawm cov concentrate coarse nkag mus rau hauv cov txheej txheem tom ntej yog txo qis heev, thiab qib tau zoo dua, uas tuaj yeem txo tus nqi ntawm kev sib tsoo thiab kev ua kom zoo tom qab. Kev ua kom zoo ntawm sensor ntse tsis sib xws los ntawm kev xaiv phau ntawv ib txwm muaj, kev sib cais magnetic, thiab kev sib cais photoelectric hauv cov nqe lus ntawm kev txheeb xyuas qhov tseeb, kev teb ceev, kev xaiv. kev ua haujlwm zoo, thiab lub peev xwm ua tiav. Kev txheeb xyuas kev txawj ntse yog qhov kev qhia dav dav ntawm cov thev naus laus zis niaj hnub thiab cov thev naus laus zis digital, thiab tau dhau los ua qhov kev taw qhia tseem ceeb ntawm kev xaiv cov khoom siv ua ntej.
Cov peev txheej hauv Suav teb feem ntau yog cov pob zeb tsis muaj zog, thiab lub peev xwm khaws cia loj heev. Yuav ua li cas pov tseg cov khib nyiab ua ntej, txhim kho qhov ua tau zoo ntawm kev sib tsoo thiab kev siv tau zoo tom qab, thiab txo tus nqi ntawm kev siv tau zoo, thiab teb rau lub teb chaws cov kev xav tau dav dav ntawm "kev tsim cov chaw zeb ntse thiab cov chaw zeb ntsuab", nws yuav dhau los ua qhov tsis zam hauv kev txhim kho kev lag luam tsuas hauv kuv lub teb chaws. Yog li ntawd, kev tsim cov khoom siv cais ntse uas haum rau cov chaw zeb hauv tsev yuav tshwm sim sai sai, thiab kev cia siab ntawm kev ua lag luam yuav dav heev.
