Cov av nkos saw yog cov hmoov pob zeb thiab dej sib xyaw ua ke thaum lub sijhawm txiav thiab txhuam cov marble thiab granite. Ntau thaj chaw nyob rau sab qaum teb ntawm peb lub tebchaws yog cov chaw tseem ceeb rau kev ua cov pob zeb, thiab muaj ntau cov av nkos saw txhua xyoo, thiab nws cov khoom sib sau ua ke siv thaj chaw loj ntawm cov peev txheej av. Cov hmoov pob zeb muaj cov qauv zoo thiab nyuaj rau pov tseg. Nws yooj yim ya saum ntuj thaum muaj cua hlob, thiab ntws mus rau hauv tus dej nrog dej nag thaum hnub los nag, ua rau muaj kuab paug rau ib puag ncig.
Cov pob zeb tseem ceeb hauv cov av nkos suav nrog feldspar, quartz, calcite, dolomite, amphibole, thiab lwm yam. Cov hlau tseem ceeb thiab cov khoom tsis huv suav nrog hlau silicate xws li hlau tshuab, magnetite, hlau oxide, pyrite, thiab biotite. Tam sim no, txoj kev siv dav dav ntawm cov av nkos yog feem ntau yog tsim cov cib ua los ntawm cov pob zeb thiab ua cov khoom siv ceramic tom qab tshem tawm cov khoom tsis huv. Tus thawj muaj peev xwm ua tiav loj thiab tus tom kawg muaj txiaj ntsig zoo rau kev lag luam.
Kev tshawb fawb txog kev pab cuam
Hauv tsab xov xwm no, kev tshawb fawb txog kev siv thiab kev ua kom zoo dua qub tau ua tiav rau cov av nkos uas sawv cev hauv thaj chaw Jining. Cov zaub mov muaj nqis hauv cov av nkos uas pom yog feldspar, hlau tshuab, hlau sib nqus, thiab lwm yam, thiab cov khoom tsis zoo yog limonite, biotite, muscovite, calcite, dolomite, hornblende, thiab lwm yam. Qhov loj ntawm cov khoom tsis sib xws, cov khoom sib xyaw yog li ntawm 1-4 hli thiab qee qhov -0.037 hli av nkos zoo. Ntawm lawv, cov hlau tshuab tsim tawm thaum lub sijhawm ua tiav thiab cov hlau sib nqus hauv cov hlau nyoos tuaj yeem sib cais ua cov khoom sib nqus. Tom qab kev sib cais sib nqus muaj zog, cov hlau uas muaj cov khoom tsis huv xws li limonite, biotite, thiab amphibole tuaj yeem raug tshem tawm. Cov khoom sib xyaw pob zeb, txhua ntu ntawm cov khoom sib nqus tuaj yeem siv ua cov cib aerated lossis cov ntaub ntawv cement, kom ua tiav lub hom phiaj ntawm kev siv dav dav.
1.Kev txiav txim siab txog cov txheej txheem
Ua ke cov khoom ntawm cov qauv sawdust los txiav txim siab txog cov txheej txheem zoo: cov hlau nyoos yog sieved los ntawm 30 meshes-+30 mesh coarse-grain sib tsoo rau -30 mesh。
——-30 mesh sib xyaw cov qauv hlau sib cais los ntawm lub nruas sib nqus sib cais + phaj tiaj tus + lub nplhaib ntsug + lub nplhaib ntsug muaj zog tshem tawm hlau sib nqus - cov khoom sib xyaw tau muab faib ua +300 mesh nruab nrab-nplej feldspar concentrate khoom thiab -300 mesh av nplaum zoo——Cov sludge zoo ces siv los tshem tawm hlau ob zaug los ntawm electromagnetic slurry kom tau txais cov khoom hmoov zoo-qib concentrate.
2.Kev xeem sib cais sib nqus ntawm cov hlau nyoos
Cov hlau nyoos tau raug sieve nrog 30 meshes, thiab cov txiaj ntsig ntawm kev tshuaj xyuas tau qhia nyob rau hauv Rooj 1.
Rooj 1. Cov txiaj ntsig ntawm Kev Pabcuam thiab Kev Tshuaj Xyuas
Zom cov hlau nplaum uas muaj cov txiaj ntsig ntawm 17.35% txog -30 mesh, sib tov nrog cov khoom hauv qab lub sieve, thiab dhau los ntawm cov txheej txheem sib cais sib nqus ntawm lub nruas sib nqus sib cais + phaj tiaj tus + lub nplhaib ntsug + lub nplhaib ntsug. Cov txheej txheem ntws tau qhia hauv Daim Duab 1, thiab cov txiaj ntsig sim tau qhia hauv Rooj 2.

Rooj 2. Cov txiaj ntsig ntawm kev sim sib cais sib nqus ib txwm muaj
Cov hlau nyoos yog tshuaj ntsuam + sib tsoo hlau + peb zaug tshem tawm hlau cov txheej txheem ib txwm muaj, thiab cov khoom nruab nrab thiab qis kawg tuaj yeem tau txais nrog cov txiaj ntsig ntawm 92.57%, Fe2O3 cov ntsiab lus ntawm 0.525% thiab dawb ntawm 36.15%. Nws yuav tsum tau txiav txim siab los ntxuav cov hlau oxide zoo thiab hlau silicate hauv cov av nkos zoo nrog lub tshuab slurry electromagnetic nruab nrab zoo tom qab kev faib tawm.
3. Tshem tawm hlau ntawm cov av nplaum zoo
Qhov thib ob concentrate ntawm Lihuan raug tso tawm ntawm cov sludge zoo hauv qab -300 mesh los ntawm overflow, thiab cov txheej txheem ntawm kev tshem tawm hlau ob zaug los ntawm lub tshuab electromagnetic slurry yog siv los tau txais cov khoom hmoov zoo concentrate. Cov txheej txheem ntws tau qhia hauv Daim Duab 2, thiab cov txiaj ntsig ntawm kev sim tau qhia hauv Rooj 3.
