Kev Taw Qhia Txog Slag
Cov khib nyiab slag yog cov khib nyiab hauv kev lag luam uas tsis suav nrog hauv cov txheej txheem ua hlau. Ntxiv rau cov hlau ore thiab roj, yuav tsum ntxiv cov limestone kom txaus ua cov tshuaj yaj kom txo qhov kub ntawm kev sib xyaw. Cov calcium oxide, magnesium oxide thiab cov khib nyiab hauv cov hlau ore uas tau los ntawm lawv cov decomposition hauv lub cub tawg, nrog rau cov tshauv hauv coke raug yaj, ua rau cov khoom yaj nrog silicate thiab silicoaluminate ua cov khoom tseem ceeb, uas ntab rau ntawm qhov chaw ntawm cov hlau yaj. Nws raug tso tawm tas li ntawm qhov chaw tso tawm slag thiab quenched los ntawm huab cua lossis dej kom tsim cov khoom me me. Qhov no yog granulated blast furnace slag, hu ua "slag". Slag yog ib hom khoom siv nrog "muaj peev xwm hydraulic", uas yog, nws yog anhydrous thaum nws nyob ib leeg, tab sis nws qhia txog qhov tawv ntawm dej nyob rau hauv kev ua ntawm qee cov activators (lime, clinker hmoov, alkali, gypsum, thiab lwm yam).
Daim ntawv thov ntawm slag
1. Cov cement slag Portland yog tsim los ua cov khoom siv raw. Cov slag granulated blast furnace yog sib xyaw nrog Portland cement clinker, thiab tom qab ntawd ntxiv 3 ~ 5% gypsum rau hauv kev sib tov thiab zom kom ua slag Portland cement. Nws tuaj yeem siv tau zoo dua hauv kev tsim dej, chaw nres nkoj thiab kev tsim av hauv av.
2. Nws siv tau los tsim cov cib slag thiab cov khoom siv slag uas ntub dej
3. Muab cov dej slag thiab cov activator (cement, lime thiab gypsum) rau ntawm lub tshuab sib tsoo log, ntxiv dej thiab zom rau hauv mortar, thiab tom qab ntawd sib tov nrog cov pob zeb loj kom ua cov pob zeb ntub dej dov.
4. Nws tuaj yeem npaj cov pob zeb slag thiab siv dav hauv kev tsim kho txoj kev thiab kev tsheb ciav hlau.
5. Daim ntawv thov ntawm cov slag nthuav dav thiab cov hlaws dai nthuav dav nthuav dav slag feem ntau yog siv los ua cov khoom sib xyaw ua ke los ua cov pob zeb sib xyaw.

Kev tshuaj xyuas ntawm cov qauv sib tsoo
Lub tshuab zeb ntsug:
Cov khoom siv loj thiab cov zis siab tuaj yeem ua tau raws li qhov ntau lawm. Lub tshuab zeb ntsug muaj kev ruaj khov siab. Qhov tsis zoo: tus nqi peev txheej khoom siv siab.
Theem I:Ckev siv cov khoom siv raw
Qhov lojcov av nplaumCov khoom siv raug tsoo los ntawm lub crusher kom txog thaum qhov pub mis zoo (15mm-50mm) uas tuaj yeem nkag mus rau hauv lub tshuab sib tsoo.
TheemII: Gkev ua kom tawv
Qhov raug tsoocov av nplaumCov ntaub ntawv me me raug xa mus rau lub hopper cia khoom los ntawm lub elevator, thiab tom qab ntawd xa mus rau chav sib tsoo ntawm lub zeb kom sib npaug thiab ntau los ntawm lub feeder rau kev sib tsoo.
Theem III:Faib pawgkev ua
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.
TheemV: Ckev 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 slag
Tus qauv thiab tus lej ntawm cov khoom siv no: 1 teeb ntawm HLM2100
Ua cov khoom siv raw: Slag
Qhov zoo ntawm cov khoom tiav: 200 mesh D90
Peev Xwm: 15-20 T / h
Tus nqi ua tsis tiav ntawm Hongcheng slag zeb yog qis heev, kev ua haujlwm ruaj khov heev, suab nrov tsawg, kev sau cov plua plav zoo dua, thiab qhov chaw ua haujlwm yog tus phooj ywg ib puag ncig. Ntxiv mus, peb zoo siab heev uas tus nqi tso zis ntawm lub zeb tau dhau qhov xav tau thiab tsim cov txiaj ntsig zoo rau peb lub tuam txhab. Hongcheng pab pawg tom qab muag tau muab kev pabcuam zoo thiab zoo siab heev. Lawv tau rov qab mus xyuas ntau zaus los xyuas qhov xwm txheej ua haujlwm ntawm cov khoom siv, daws ntau yam teeb meem rau peb, thiab teeb tsa ntau qhov kev lees paub rau kev ua haujlwm ib txwm ntawm cov khoom siv.
