Kev Taw Qhia Txog Kaolin
Kaolin tsis yog tsuas yog ib qho av nplaum xwb, tab sis kuj yog ib qho tseem ceeb heev uas tsis yog hlau. Nws tseem hu ua dolomite vim nws yog dawb. Kaolin ntshiab yog dawb, zoo thiab mos, nrog rau kev ua kom zoo, tiv taus hluav taws, ncua kev kawm, nqus thiab lwm yam khoom siv lub cev. Lub ntiaj teb muaj cov peev txheej kaolin nplua nuj, nrog rau tag nrho kwv yees li 20.9 billion tons, uas tau faib dav dav. Tuam Tshoj, Tebchaws Meskas, Tebchaws Askiv, Brazil, Is Nrias teb, Bulgaria, Australia, Russia thiab lwm lub tebchaws muaj cov peev txheej kaolin zoo. Tuam Tshoj cov peev txheej kaolin yog cov saum toj kawg nkaus hauv ntiaj teb, nrog 267 thaj chaw tsim cov hlau pov thawj thiab 2.91 billion tons ntawm cov peev txheej pov thawj.
Kev siv cov kaolin
Cov kaolin ores uas tsim los ntawm ntuj muaj peb pawg: thee thee, kaolin mos thiab kaolin xuab zeb raws li qhov zoo ntawm cov ntsiab lus, plasticity, thiab ntawv xuab zeb. Cov chaw siv sib txawv xav tau cov kev xav tau zoo sib txawv, xws li cov ntawv txheej feem ntau xav tau qhov kaj siab, viscosity qis thiab concentration ntawm cov khoom me me; kev lag luam ceramic xav tau plasticity zoo, formability thiab firing whiteness; Refractory xav tau refractoriness siab; kev lag luam enamel xav tau kev ncua zoo, thiab lwm yam. Tag nrho cov no txiav txim siab cov lus qhia ntawm kaolin ntawm cov khoom, ntau hom. Yog li ntawd, cov peev txheej sib txawv, feem ntau txiav txim siab nws cov kev coj ua ntawm cov peev txheej muaj rau kev txhim kho kev lag luam.
Feem ntau hais lus, cov kaolin thee hauv tsev (kaolin tawv), yog qhov tsim nyog dua rau kev tsim kho ua calcined kaolin, feem ntau yog siv rau hauv cov khoom sau ntawm ntau yam kev siv. Vim nws cov calcined kaolin dawb siab, tuaj yeem siv rau hauv kev ua ntawv, tshwj xeeb tshaj yog rau kev tsim cov ntawv coated zoo, tab sis feem ntau nws tsis siv ib leeg vim tias cov av calcined kaolin feem ntau yog siv los ua kom dawb dua, cov tshuaj tsawg dua li cov av ntxuav hauv kev ua ntawv. kaolin tsis muaj thee (av nplaum mos thiab av nplaum xuab zeb), feem ntau yog siv rau hauv kev lag luam ntawv txheej thiab kev lag luam ceramic.
Cov txheej txheem sib tsoo Kaolin
Kev tshuaj xyuas cov khoom siv raw ntawm kaolin

Kev xaiv cov qauv ntawm lub tshuab ua hmoov kaolin
| Cov Lus Qhia (mesh) | Hmoov zoo 325mesh | Kev ua cov hmoov zoo heev (600 mesh-2000 mesh) |
| Kev xaiv cov khoom siv | Lub tshuab sib tsoo ntsug lossis lub tshuab sib tsoo raymond | |
* Lus Cim: xaiv lub tshuab tseem ceeb raws li qhov tso zis thiab qhov zoo uas yuav tsum tau ua
Kev tshuaj xyuas ntawm cov qauv sib tsoo
1. Raymond Mill: Raymond Mill yog cov nqi qis, muaj peev xwm siab, siv hluav taws xob tsawg, cov khoom siv ruaj khov, suab nrov tsawg; yog lub tshuab ua kom txuag hluav taws xob zoo rau cov hmoov zoo hauv qab 600mesh.
2. Lub tshuab zeb ntsug: cov khoom siv loj, muaj peev xwm siab, kom ua tau raws li qhov ntau lawm. Lub tshuab zeb ntsug muaj kev ruaj khov siab dua. Qhov tsis zoo: cov khoom siv yog cov nqi peev txheej siab.
Theem I: Kev tsoo cov khoom siv raw
Cov khoom siv kaolin loj yog crushed los ntawm lub crusher mus rau qhov pub fineness (15mm-50mm) uas tuaj yeem nkag mus rau hauv lub tshuab sib tsoo.
Theem II: Kev Sib Tsoo
Cov ntaub ntawv me me kaolin uas raug tsoo raug xa mus rau lub hopper cia khoom los ntawm lub tshuab nqa, thiab tom qab ntawd xa mus rau chav sib tsoo ntawm lub zeb kom sib npaug thiab ntau los ntawm lub tshuab pub rau kev sib tsoo.
Theem III: Kev Faib Pawg
Cov ntaub ntawv milled raug ntsuas los ntawm lub tshuab ntsuas qib, thiab cov hmoov tsis tsim nyog raug ntsuas los ntawm lub classifier thiab xa rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo dua.
Theem V: Kev sau cov khoom tiav lawm
Cov hmoov uas ua raws li qhov zoo yuav ntws los ntawm cov kav dej nrog cov roj thiab nkag mus rau hauv lub tshuab nqus plua plav kom sib cais thiab sau. Cov hmoov uas sau tau tiav lawm yuav raug xa mus rau lub silo ntawm cov khoom tiav lawm los ntawm lub cuab yeej xa khoom los ntawm qhov chaw tawm, thiab tom qab ntawd ntim los ntawm lub tanker hmoov lossis lub tshuab ntim khoom tsis siv neeg.
Cov piv txwv ntawm kev siv cov hmoov kaolin
Cov ntaub ntawv ua tiav: pyrophyllite, kaolin
Qhov zoo: 200 mesh D97
Cov zis: 6-8t / h
Kev teeb tsa khoom siv: 1 teeb ntawm HC1700
Lub tshuab sib tsoo ntawm HCM yog qhov kev xaiv zoo heev los koom tes nrog lub tuam txhab zoo li no nrog lub kaw lus lav zoo tom qab muag. Hongcheng kaolin sib tsoo tshuab yog cov khoom siv tshiab rau kev txhim kho lub tshuab ib txwm muaj. Nws cov zis yog 30% - 40% siab dua li ntawm Raymond tshuab ib txwm muaj ntev dhau los, uas ua rau kev ua haujlwm zoo dua thiab cov zis ntawm lub tshuab chav tsev zoo dua. Cov khoom tiav lawm muaj kev sib tw ua lag luam zoo thiab nrov heev hauv peb lub tuam txhab.
