Maburashi a kaboni ndi zinthu zofunika kwambiri pamakina amagetsi a simenti, zomwe zimathandiza kuti magetsi azitha kuyenda pakati pa zida zofunika komanso zozungulira. Ntchito zawo zazikulu m'mafakitale a simenti zikuphatikizapo ma rotary kiln drives, ma simenti mill motors, ma conveyor belt motors, ndi mafani osonkhanitsa fumbi. Zipangizozi zonyamula katundu wambiri komanso zopitilira muyeso zimadalira maburashi a kaboni kuti asunge mphamvu yokhazikika, zomwe ndizofunikira kwambiri pa unyolo wonse wopanga simenti—kuyambira kuphwanya zinthu zopangira mpaka kupukuta kwa clinker ndi kulongedza zinthu zomalizidwa.
Kusankha maburashi oyenera a kaboni pa mafakitale a simenti kumafuna kuwerengera mikhalidwe yovuta yogwirira ntchito: kutentha kwambiri, fumbi lolemera, ndi kugwedezeka kwambiri. Zofunikira zazikulu zimaphatikizapo mtundu wa zinthu: maburashi a graphite olumikizidwa ndi resin amapambana m'malo okhala ndi fumbi lochuluka chifukwa cha kukana kuwonongeka, pomwe maburashi achitsulo-graphite amakondedwa pazida zamagetsi monga ma rotary kiln drives. Kugwirizana kwa kukula ndikofunikira—maburashi ayenera kukwanira bwino zogwirira kuti fumbi lisalowe komanso kuti lisakhudze bwino. Kuphatikiza apo, kusankha maburashi olimbana ndi kutentha kwambiri (mpaka 150°C kapena kupitirira apo) kumathandizira kuti chomera cha simenti chikhale cholimba.
Machenjezo ofunikira amaonetsetsa kuti ntchito ikuyenda bwino. Kuyang'anitsitsa nthawi zonse ndikofunikira kuti muchotse fumbi ndi simenti zomwe zasonkhanitsidwa m'zogwirira burashi, chifukwa zinyalala zimayambitsa kugwedezeka komanso kuwonongeka mwachangu. Yang'anirani kutalika kwa burashi mosamala—sinthani pamene yatsika pansi pa malire omwe wopanga amalangiza (nthawi zambiri 5–8mm). Sungani kupanikizika koyenera kwa kasupe: kupanikizika kosakwanira kumabweretsa kusagwirizana koipa, pomwe kupanikizika kochulukirapo kumawonjezera kukangana. Kugwiritsa ntchito zogwirira burashi zosapsa fumbi komanso kuchita kuyeretsa nthawi ndi nthawi kumawonjezera nthawi yogwira ntchito ya burashi ya carbon ndikuchepetsa nthawi yogwira ntchito ya zida, zomwe ndizofunikira kwambiri pakupanga kosalekeza kwa zomera za simenti.
Mwachidule, maburashi a kaboni amagwira ntchito yofunika kwambiri pa ntchito za fakitale ya simenti. Kusankha kolunjika kutengera mtundu wa zida ndi momwe ntchito ikuyendera, pamodzi ndi njira zosamalira mosamala, kumatsimikizira kuti ntchitoyo ikuyenda bwino komanso kwanthawi yayitali m'malo ovuta amakampani.
