Kev Taw Qhia Txog Cov Cement Clinker
Cement clinker yog cov khoom tiav ib nrab ua los ntawm limestone thiab av nplaum, cov khoom siv hlau ua cov khoom siv tseem ceeb, tsim ua cov khoom siv raw raws li qhov sib piv tsim nyog, hlawv kom txog thaum ib feem lossis tag nrho cov yaj, thiab tau txais tom qab txias. Hauv kev lag luam cement, cov khoom siv tshuaj lom neeg tseem ceeb ntawm Portland cement clinker feem ntau yog calcium oxide, silica thiab me me ntawm alumina thiab hlau oxide. Cov khoom siv tseem ceeb yog tricalcium silicate, dicalcium silicate, tricalcium aluminate thiab hlau aluminate tetracallic acid, Portland cement clinker ntxiv rau qhov ntau ntawm gypsum tom qab sib tsoo tuaj yeem ua rau portland cement.
Kev siv cov cement clinker
Tam sim no, cov cement clinker siv dav hauv kev tsim kho pej xeem thiab kev lag luam, xws li kev ua cementing ntawm cov chaw roj thiab cov chaw roj av, cov pas dej loj hauv cov haujlwm txuag dej, cov haujlwm kho tub rog, nrog rau cov khoom siv acid thiab refractory, txhaj tshuaj rau hauv lub qhov av es tsis yog qhov av. Tsis tas li ntawd, ntoo thiab hlau tuaj yeem siv hloov ntoo rau ntau yam kev siv xws li cov ncej xov tooj, cov chaw pw tsheb ciav hlau, cov kav dej roj thiab roj av, thiab cov chaw khaws roj thiab cov chaw khaws roj.

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 kev tsim khoom loj. Qhov noCement Clinker Millmuaj kev ruaj khov siab. Qhov tsis zoo: tus nqi peev txheej khoom siv siab.
Theem I:Ckev siv cov khoom siv raw
Qhov lojcov cement clinkerCov 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 cement clinkerCov 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 cement clinker
Guilin Hongcheng cement clinker sib tsoo tshuab yog ruaj khov thiab cov khoom siv thiab cov khoom zoo heev. Ntawm lawv, lub tswv yim ntawm kev tiv thaiv ib puag ncig yog qhov tseem ceeb heev. Cov hmoov av ntau dhau hauv lub chaw ua haujlwm pulverizing yog qhov me me heev, tag nrho ib puag ncig huv si thiab huv si, thiab kev siv hluav taws xob kuj tsawg heev. Qhov no tseem ceeb heev rau cov tuam txhab tsim khoom, uas ncaj qha txo cov nqi tsim khoom thiab kev ua haujlwm thiab txuag ntau cov nuj nqis rau cov tuam txhab pulverizing. Yog li ntawd, qhov no yog lub zeb nrog kev ua tau zoo heev.
