Los ntawm limestone chaw txua txiag zeb mus rau kev xa khoom ntawm cov khoom kawg, ua raws txhua kauj ruam hauv cov txheej txheem cementmanufacturing
- Kauj ruam 1: Mining.
- Kauj ruam 2: Crushing, stacking, thiab reclaiming ntawm raw khoom.
- Kauj ruam 3: Raw zaub mov kom qhuav, sib tsoo, thiab homogenization.
- Kauj ruam 4: Clinkerization.
- Kauj ruam 5: Cement sib tsoo thiab khaws cia.
- Kauj ruam 6: Ntim.
Hauv qhov no, puas yog cement yog raw khoom?
Cov raw khoom xav tau los tsim cement (calcium carbonate, silica, alumina thiab hlau ore) yog tsim los ntawm limestone pob zeb, chalk, clayey schist orclay. Suitable reserves muaj nyob rau hauv ntau lub teb chaws. Cov no raw khoom yog muab rho tawm los ntawm quarrybyblasting.
Ib yam li ntawd, cov tshuaj muaj pes tsawg leeg ntawm cov cement yog dab tsi? Txiv qaub los yog calcium oxide, CaO: los ntawm limestone, chalk, plhaub, shale los yog calcareous pob zeb. Silica, SiO2: los ntawm cov xuab zeb, cov fwj qub, av nplaum los yog pob zeb alumina, Al2O3: los ntawm bauxite, recycledaluminum, av nplaum. Iron, Fe2O3: los ntawm av nplaum, hlau ore, scrapiron thiab ya tshauv.
Qhov thib ob, cement formula yog dab tsi?
Kho tshiab Lub Xya hli ntuj 27, 2017. Cement yog ib qho kev sib xyaw ntawm cov khoom sib txawv. Nws muaj Calciumoxide (CaO), Silicondioxide (SiO2), Aluminumoxide (Al2O3), Ironoxide (Fe2O3), Dej (H2O), Sulfate (SO3) thiab tsis muaj qhov tshwj xeeb. qauv.
Cov khoom siv raw yog dab tsi?
Cov khoom siv raw tuaj yeem piav qhia raws li cov khoom siv khoom siv nyob rau hauv kev tsim khoom lossis thawj cov khoom lag luam. Feem ntau, raw khoom yog natural resources xws li roj, ntoo, thiab hlau. Cov khoom siv raw feem ntau hloov forusein ntau yam txheej txheem ua ntej ua siv txheej txheem inthemanufacturing.

Dab tsi yog kauj ruam kawg ntawm xya kauj ruam kev muag tus kheej?
Cov txheej txheem muag tus kheej yog xya kauj ruam mus kom ze: prospecting, pre-mus kom ze, mus kom ze, kev nthuav qhia, rooj sib tham tsis pom zoo, kaw qhov muag, thiab ua raws
Muaj pes tsawg kauj ruam nyob rau hauv xya kauj ruam txhim kho?
Xya kauj ruam
Cov kauj ruam hauv peb kauj ruam sau ntawv yog dab tsi?
Hauv cov ntsiab lus dav dav, txheej txheem sau ntawv muaj peb qhov tseem ceeb: sau ua ntej, sau, thiab sau ntawv tom qab. Peb qhov no tuaj yeem muab faib ua 5 kauj ruam ntxiv: (1) Kev Npaj; (2) Kev sib sau ua ke; (3) Composing / Drafting; (4) Kev hloov kho / kho; thiab (5) Pro ofreading
Thawj kauj ruam ntawm 7 kauj ruam txhim kho yog dab tsi?
