Tube zeb yog ib qho tseem ceeb ntawm cov khoom siv hauv kev lag luam.
Ua los ntawm lub tog raj kheej, pub thiab tso tawm cov khoom siv, cov khoom sib hloov, thiab cov tshuab xa tawm, lub raj zeb ua haujlwm los ntawm kev tig lub tog raj kheej kom tsav cov kev sib tsoo tawm sab hauv, xws li cov pob hlau lossis cov pas nrig, kom cuam tshuam, zom, thiab compress cov ntaub ntawv. Cov txheej txheem no grinds cov ntaub ntawv mus rau qhov xav tau particle loj.
Nws muaj ob peb qhov zoo. Ua ntej, nws muaj peev xwm ua tau loj, ua tau raws li qhov xav tau ntawm kev tsim khoom loj. Thib ob, nws muab cov txiaj ntsig zoo sib tsoo, ua tiav qhov loj me me thiab txhim kho cov khoom zoo. Ntxiv mus, lub raj zeb zeb yog qhov hloov tau zoo heev thiab tuaj yeem ua cov ntaub ntawv ntawm ntau yam hardnesses thiab av noo.
Hauv kev lag luam mining, nws feem ntau siv rau kev sib tsoo ores los pab txhawb cov txheej txheem tom ntej. Hauv cov khoom siv hauv tsev, nws grinds cement, ya tshauv, thiab lwm yam khoom siv los tsim cov khoom siv zoo. Hauv kev lag luam tshuaj, nws finely grinds ntau yam tshuaj raw khoom.
Txawm li cas los xij, nws kuj muaj qee qhov tsis zoo, xws li kev siv hluav taws xob siab thiab cov nqi khiav lag luam kuj siab. Kev tu thiab tu yuav tsum muaj kev txawj ntse thiab kev nqis peev. Hauv kev xaus, lub raj zeb yog ib qho tseem ceeb ntawm kev sib tsoo cov cuab yeej nrog kev siv dav hauv ntau qhov kev lag luam.
