Pom av nkos yog sib xyaw ntawm pob zeb hmoov thiab dej uas tsim thaum lub sij hawm txiav thiab polishing ntawm marble thiab granite.Ntau qhov chaw nyob rau sab qaum teb ntawm peb lub teb chaws yog ib qho tseem ceeb pob zeb ua hauv paus, thiab ib tug loj npaum li cas ntawm saw av nkos yog tsim txhua txhua xyoo, thiab nws stacking yuav siv sij hawm. mus txog thaj tsam loj ntawm thaj av.Cov hmoov zeb zeb muaj qhov zoo nkauj zoo nkauj thiab nyuaj rau kev pov tseg.Nws yog ib qho yooj yim los ya saum ntuj nyob rau hauv cov cua muaj zog, thiab ntws mus rau hauv tus dej nrog cov dej nag nyob rau hauv cov hnub los nag, ua rau muaj kuab paug loj heev.
Lub ntsiab gangue minerals nyob rau hauv cov av nkos muaj xws li feldspar, quartz, calcite, dolomite, amphibole, thiab lwm yam. Cov hlau tseem ceeb thiab impurities muaj xws li hlau silicate xws li mechanical hlau, magnetite, hlau oxide, pyrite, thiab biotite.Tam sim no, kev siv dav siv. txoj kev pom av nkos yog tsuas yog los tsim cov pob zeb aerated bricks thiab ua cov khoom siv ceramic tom qab tshem tawm impurities.Lub qub muaj peev xwm ua tau loj thiab tom kawg muaj txiaj ntsig kev lag luam siab.
Kev tshawb fawb tau txais txiaj ntsig
Hauv tsab xov xwm no, kev tshawb fawb txog kev siv thiab txiaj ntsig kev sim yog ua rau cov neeg sawv cev pom av nkos hauv cheeb tsam Jining.Cov khoom muaj txiaj ntsig hauv cov av nkos yog feldspar, mechanical hlau, hlau nplaum, thiab lwm yam, thiab cov khoom tsis zoo yog limonite, biotite, muscovite, calcite, dolomite, hornblende, thiab lwm yam. Cov khoom loj yog tsis sib npaug, cov ntxhib hais yog nyob ntawm 1-4mm thiab qee qhov -0.037mm nplua av nkos. Ntawm lawv, cov khoom siv hlau tsim thaum lub sij hawm ua thiab cov hlau nplaum hlau hauv cov raw khoom. ore tuaj yeem sib nqus sib nqus rau hauv cov khoom siv hlau.Tom qab muaj zog sib nqus sib cais, hlau-muaj impurities xws li limonite, biotite, thiab amphibole tuaj yeem raug tshem tawm.Pob zeb concentrate cov khoom, txhua ntu ntawm cov hlau nplaum tailings tuaj yeem siv los ua aerated cib lossis cov khoom siv cement, kom ua tiav lub hom phiaj ntawm kev siv dav.
1.Kev txiav txim siab ntws
Kev sib xyaw cov khoom ntawm cov qauv sawdust los txiav txim siab cov txheej txheem tau txais txiaj ntsig: cov ore raw sieved los ntawm 30 meshes- + 30 mesh coarse-grain sib tsoo rau -30 mesh.
——-30 mesh sib xyaw qauv hlau sib cais los ntawm nruas sib nqus sib cais + phaj tiaj + ntsug nplhaib + ntsug nplhaib muaj zog sib nqus hlau tshem tawm-cov concentrate yog muab faib ua +300 mesh nruab nrab-grain feldspar concentrate cov khoom thiab -300 mesh nplua av nkos——Cov sludge zoo yog siv los tshem tawm cov hlau ob zaug los ntawm electromagnetic slurry kom tau txais cov hmoov zoo-qib concentrate cov khoom.
2.Raw ore sib nqus sib cais kuaj
Cov ore raw tau sieved nrog 30 meshes, thiab cov kev soj ntsuam tau qhia nyob rau hauv Table 1.
Table 1. Cov txiaj ntsig tau txais txiaj ntsig thiab kev tshuaj ntsuam xyuas
Sib tsoo cov ntxhib-grained ore nrog cov txiaj ntsig ntawm 17.35% mus rau -30 mesh, sib tov nrog cov khoom hauv qab lub sieve, thiab mus dhau cov txheej txheem sib nqus sib nqus sib nqus ntawm nruas sib nqus sib nqus + phaj tiaj + ntsug nplhaib + ntsug nplhaib.Cov txheej txheem ntws tau qhia hauv daim duab 1, thiab cov txiaj ntsig kev xeem tau qhia hauv Table 2.
Daim duab 1. Cov txheej txheem ntws ntawm cov pa sib nqus sib cais kuaj ntawm cov ore raw.
Table 2. Cov txiaj ntsig ntawm cov qauv sib nqus sib nqus sib cais
Cov ore raw yog kuaj + ore sib tsoo + peb-lub sij hawm hlau tshem tawm cov txheej txheem kev sim, thiab cov khoom nruab nrab thiab qis-kawg mloog zoo tuaj yeem tau txais nrog cov txiaj ntsig ntawm 92.57%, Fe2O3 cov ntsiab lus ntawm 0.525% thiab whiteness ntawm 36.15%. Nws yuav tsum tau txiav txim siab los ntxuav cov nplua-grained hlau oxide thiab hlau silicate nyob rau hauv cov av nkos zoo nrog ib tug nplua nruab nrab, high-field electromagnetic slurry tshuab tom qab kev faib tawm.
3.Iron tshem tawm los ntawm nplua av nkos slurry
Qhov thib ob mloog zoo ntawm Lihuan yog tawm los ntawm cov nplua sludge hauv qab -300 mesh los ntawm cov dej ntws, thiab cov txheej txheem ntawm kev tshem tawm cov hlau ob zaug los ntawm lub tshuab electromagnetic slurry yog siv kom tau cov hmoov zoo concentrate cov khoom.Cov txheej txheem ntws tau qhia hauv daim duab 2, thiab cov txiaj ntsig kev xeem tau qhia hauv Table 3.
Daim duab 2. Cov txheej txheem ntws ntawm cov av nkos slurry hlau tshem tawm zoo
Table 3. Hlau tshem tawm Performance index ntawm nplua av nkos slurry
Tom qab muab qhab nia Lihuan mloog zoo, qhov dawb ntawm +300 mesh nruab nrab-grain feldspar concentrate tau nce los ntawm 36.15% mus rau 56.49%, thiab cov xim dawb ntawm cov av nkos txo qis rau 23.07%.-300 mesh nplua sludge raug tshem tawm ntawm cov hlau ob zaug los ntawm electromagnetic slurry, thiab ceramic-qib hmoov zoo cov khoom lag luam nrog cov txiaj ntsig ntawm 42.31% thiab whiteness ntawm 41.80% tuaj yeem tau.
3.Txhua txoj kev xeem
Kev ntsuas kev ntsuas thiab ntsuas ntsuas kom ua tiav tag nrho cov txheej txheem xeem.
Daim duab 3. Tag nrho cov txheej txheem ntawm sawing av nkos txheej txheem
Table 4. Ntsuas ntsuas rau tag nrho cov txheej txheem
Daim ntawv txuas: Biscuits kub 1200 ℃
Pom cov av nkos yog sieved + hauv av + tsis muaj zog sib nqus sib cais + tiaj tus phaj + ntsug nplhaib + ntsug nplhaib + grading electromagnetic slurry sib nqus sib nqus txheej txheem kom tau cov hlau ore nrog cov txiaj ntsig ntawm 0.32% thiab qib TFe ntawm 62.35%.Nrog rau kev tawm los ntawm 38.56% thiab whiteness ntawm 54.69% ntawm nruab nrab-grain ceramic qib feldspar concentrate cov khoom thiab ib tug tawm los ntawm 42.31% ntawm whiteness ntawm 41.80% zoo hmoov ceramic qib concentrate cov khoom;tag nrho cov txiaj ntsig ntawm kev sib nqus tailings yog 18.81%, tuaj yeem siv los ua cov khoom siv raw rau aerated cib.
Cov txheej txheem thev naus laus zis no tso cai rau kev siv dav dav ntawm cov av nkos tailings, thiab tuaj yeem tau txais txiaj ntsig zoo dua kev lag luam thiab kev tiv thaiv ib puag ncig tseem ceeb.
