Cov txhuam carbon yog cov khoom tseem ceeb hauv cov tshuab hluav taws xob hauv cov chaw ua cement, ua rau muaj kev hloov pauv tam sim no ntawm cov khoom siv tseem ceeb thiab cov khoom siv tig. Lawv cov kev siv tseem ceeb hauv cov chaw ua cement suav nrog cov khoom siv rotary kiln, cov cav tov cement, cov cav siv conveyor, thiab cov kiv cua sau plua plav. Cov khoom siv thauj khoom siab, ua haujlwm tas mus li no vam khom cov txhuam carbon kom tswj tau qhov kev xa hluav taws xob ruaj khov, uas yog qhov tseem ceeb rau tag nrho cov saw hlau tsim cement - los ntawm cov khoom siv raw mus rau kev sib tsoo clinker thiab cov khoom tiav lawm.
Kev xaiv cov txhuam carbon uas tsim nyog rau cov chaw ua cement yuav tsum tau suav nrog cov xwm txheej ua haujlwm hnyav: kub heev, plua plav hnyav, thiab kev co hnyav. Cov qauv tseem ceeb suav nrog hom khoom siv: cov txhuam graphite uas muaj cov roj hmab sib txuas zoo tshaj plaws hauv cov chaw muaj plua plav ntau vim tias tsis yooj yim hnav, thaum cov txhuam hlau-graphite yog qhov zoo dua rau cov khoom siv hluav taws xob siab xws li cov tsav rotary kiln. Qhov sib xws ntawm qhov loj me yog qhov tseem ceeb - cov txhuam yuav tsum haum cov tuav kom zoo kom tiv thaiv cov plua plav nkag thiab tsis sib cuag zoo. Tsis tas li ntawd, kev xaiv cov txhuam uas tiv taus kub siab (txog li 150 ° C lossis siab dua) ua kom muaj kev ruaj khov nyob rau hauv cov xwm txheej ua haujlwm ntawm cov chaw ua cement.
Cov kev ceev faj tseem ceeb ua kom ntseeg tau tias muaj kev ua haujlwm zoo. Kev tshuaj xyuas tsis tu ncua yog qhov yuav tsum tau ua kom tshem tawm cov hmoov av thiab cov cement uas tau sib sau ua ke ntawm cov txhuam tuav, vim tias cov khib nyiab ua rau muaj hluav taws xob thiab hnav sai. Saib xyuas qhov ntev ntawm txhuam ze ze - hloov thaum nws poob qis dua qhov txwv uas tus neeg tsim khoom pom zoo (feem ntau 5-8 hli). Tswj lub zog ntawm lub caij nplooj ntoos hlav kom zoo: lub zog tsis txaus ua rau kev sib cuag tsis zoo, thaum lub zog ntau dhau ua rau muaj kev sib txhuam ntau ntxiv. Kev siv cov txhuam tuav uas tiv taus cov hmoov av thiab ua kev ntxuav lub tshuab hluav taws xob tsis tu ncua kuj ua rau lub neej ntawm txhuam carbon ntev dua thiab txo cov khoom siv tsis ua haujlwm, uas yog qhov tseem ceeb rau cov nroj tsuag cement cov kev xav tau tsim khoom tas mus li.
Hauv kev xaus lus, cov txhuam carbon ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov chaw ua cement. Kev xaiv raws li hom khoom siv thiab cov xwm txheej ua haujlwm, ua ke nrog cov txheej txheem kev saib xyuas nruj, ua kom muaj kev ua haujlwm zoo thiab kav ntev hauv qhov chaw nyuaj ntawm kev lag luam.
