Taw qhia rau kaolin
Kaolin tsis yog tsuas yog ib qho av nplaum ntxhia hauv cov xwm txheej xwb, tab sis kuj tseem ceeb heev uas tsis yog hlau ntxhia.Nws tseem hu ua dolomite vim nws yog dawb.Ntshiab kaolin yog dawb, nplua thiab mos, nrog cov yas zoo, hluav taws kub, kev ncua, adsorption thiab lwm yam khoom siv lub cev.Lub ntiaj teb no nplua nuj nyob rau hauv kaolin cov kev pab cuam, nrog rau tag nrho cov nyiaj ntawm 20.9 billion tons, uas yog dav faib.Tuam Tshoj, Tebchaws Asmeskas, Tebchaws Askiv, Brazil, Is Nrias teb, Bulgaria, Australia, Russia thiab lwm lub tebchaws muaj cov khoom siv kaolin zoo.Tuam Tshoj Kaolin ntxhia cov peev txheej nyob rau saum toj kawg nkaus hauv ntiaj teb, nrog 267 pov thawj ore tsim thaj chaw thiab 2.91 billion tons ntawm pov thawj pov thawj.
Kev siv kaolin
Ntuj tso kaolin ores tuaj yeem muab faib ua coal kaolin, mos kaolin thiab sandy kaolin peb pawg raws li cov ntsiab lus zoo, plasticity, sandpaper.Cov ntawv thov sib txawv tau nug txog cov kev xav tau zoo sib txawv, xws li cov ntawv coatings feem ntau xav tau qhov ci ntsa iab, tsis muaj viscosity thiab concentration ntawm cov khoom loj;ceramic kev lag luam yuav tsum tau zoo plasticity, formability thiab firing whiteness;Refractory xav tau rau siab refractoriness;enamel kev lag luam yuav tsum muaj kev ncua zoo, thiab lwm yam. Tag nrho cov no txiav txim siab cov khoom siv kaolin specifications, ntau hom hom.Yog li ntawd, cov kev pab sib txawv temperament, feem ntau txiav txim siab nws cov kev taw qhia ntawm cov peev txheej muaj rau kev tsim kho kev lag luam.
Feem ntau hais lus, cov thee hauv tsev kaolin (hard kaolin), yog qhov tsim nyog rau kev loj hlob raws li calcined kaolin, feem ntau yog siv rau hauv cov khoom siv ntawm cov ntawv sib txawv.Vim nws qhov siab dawb ntawm calcined kaolin, tuaj yeem siv rau hauv papermaking, tshwj xeeb tshaj yog rau kev tsim cov ntawv qib siab coated, tab sis feem ntau nws tsis yog siv ib leeg vim calcined kaolin av feem ntau yog siv los ua kom cov xim dawb, qhov ntau npaum li cas. tsawg dua cov av ntxuav hauv papermaking.Non-coal-bearing kaolin (mos av nplaum thiab xuab zeb av nplaum), feem ntau yog siv rau hauv daim ntawv txheej thiab ceramic kev lag luam.
Kaolin Sib tsoo txheej txheem
Kev tshuaj ntsuam xyuas ntawm kaolin raw khoom
| SiO 2 | Al22O3 | H2O |
| 46.54% | 39.5% | 13.96% |
Kaolin hmoov ua tshuab qauv xaiv qhov kev pab cuam
| Specification (mesh) | Fine hmoov 325 mesh | Kev sib sib zog nqus ntawm ultrafine hmoov (600 mesh-2000 mesh) |
| Kev xaiv khoom siv | Vertical sib tsoo zeb los yog raymond sib tsoo zeb | |
* Ceebtoom: xaiv lub tshuab tseem ceeb raws li cov khoom tsim tawm thiab kev ua kom zoo
Kev tsom xam ntawm kev sib tsoo zeb qauv
1. Raymond Mill: Raymond Mill yog tus nqi qis peev, muaj peev xwm siab, tsis muaj zog siv, khoom siv ruaj khov, tsis tshua muaj suab nrov;yog lub zog txuag hluav taws xob zoo rau cov hmoov zoo hauv qab 600mesh.
2.Vertical zeb: cov cuab yeej loj loj, muaj peev xwm ua tau raws li qhov loj-scale ntau lawm.Vertical zeb yog siab dua stability.Disadvantages: cov khoom siv yog cov peev txheej siab.
Theem I: Crushing ntawm raw khoom
Cov khoom siv kaolin loj yog crushed los ntawm lub crusher mus rau lub feed fineness (15mm-50mm) uas tuaj yeem nkag mus rau hauv kev sib tsoo zeb.
Theem II: Sib tsoo
Lub crushed kaolin cov ntaub ntawv me me raug xa mus rau lub hopper cia los ntawm lub elevator, thiab ces xa mus rau lub sib tsoo chamber ntawm lub zeb tusyees thiab quantitatively los ntawm feeder rau kev sib tsoo.
Theem III: Classifying
Cov ntaub ntawv milled tau muab qhab nia los ntawm kev muab qhab nia, thiab cov hmoov tsis tsim nyog tau muab qhab nia los ntawm cov khoom faib thiab rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo.
Theem V: Sau cov khoom tiav
Cov hmoov ua raws li kev nplua nuj ntws los ntawm cov raj xa dej nrog cov roj thiab nkag mus rau hauv cov plua plav collector rau kev sib cais thiab sib sau.Cov hmoov uas tau sau tiav yog xa mus rau cov khoom tiav silo los ntawm cov khoom siv thauj khoom los ntawm qhov chaw nres nkoj tawm, thiab tom qab ntawd ntim los ntawm cov hmoov tanker lossis tsis siv neeg ntim khoom.
Daim ntawv thov piv txwv ntawm kaolin hmoov ua
Cov khoom siv: pyrophyllite, kaolin
Fineness: 200 mesh D97
Cov zis: 6-8t / h
Cov khoom siv configuration: 1 teeb ntawm HC1700
Kev sib tsoo zeb ntawm HCM yog ib qho kev xaiv zoo heev los koom tes nrog cov lag luam zoo tshaj plaws tom qab muag kev lees paub.Hongcheng kaolin sib tsoo zeb yog cov cuab yeej tshiab rau kev txhim kho cov tsoos zeb.Nws cov zis yog 30% - 40% siab dua li cov tsoos Raymond zeb ntev dhau los, uas zoo heev txhim kho cov efficiency thiab cov zis ntawm lub tsev zeb.Cov khoom tiav ua tiav muaj kev sib tw ua lag luam zoo thiab nrov heev hauv peb lub tuam txhab.
