Nws muaj lub zog ruaj khov rau kev hloov pauv ntawm cov khoom lub cev lub cev (xws li qhov loj me, noo noo, tawv thiab lwm yam), thiab muaj peev xwm loj ntau lawm.
② Cov pulverization piv yog loj (feem ntau tshaj 300, thiab tuaj yeem ncav ntau dua 1,000 rau superfine sib tsoo), qhov khoom zoo ntawm cov khoom yog qhov zoo, thiab cov particle gradation tau yooj yim los kho.
Nws tuaj yeem hloov kho rau cov xwm txheej sib txawv ntawm kev ua haujlwm: nws tuaj yeem ua kom qhuav lossis ntub, thiab ob qhov txheej txheem ntawm ziab thiab sib tsoo tuaj yeem ua ke rau kev ua haujlwm tib lub sijhawm; nws tuaj yeem qhib-Circuit Court sib tsoo lossis kaw-Circuit Court sib tsoo.
Sealing Zoo sib khi, tuaj yeem ua haujlwm hauv qab qhov tsis zoo, thiab tsis muaj hmoov av hauv qhov chaw ua haujlwm.
Nws yooj yim rau kev tsim loj-thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev teev ntau yam kev lag luam niaj hnub.
