Cov Kav Hlau Uas Muaj Roj Hmab
Cov kav hlau uas muaj roj hmab yog tsim los siv rau ntau yam kev siv twj tso kua mis. Cov kev siv xws li kev tso tawm ntawm lub tshuab zeb, cov twj tso kua mis siab, cov kab ntev ntawm cov tailings, cov twj tso kua mis slurry uas xav tau ntau thiab cov kav dej hnyav. Txhua qhov kawg nrog cov roj hmab vulcanized foob ruaj khov.
Cov yeeb nkab hlau uas tiv taus thiab tiv taus xeb yog ua los ntawm cov yeeb nkab hlau uas siv ua cov khoom siv hauv lub cev thiab siv cov roj hmab uas tiv taus kev hnav, tiv taus xeb thiab tiv taus kub ua txheej sab hauv. Nws yog sib xyaw los ntawm cov thev naus laus zis tshwj xeeb nrog cov nplaum ua haujlwm siab. Feem ntau siv rau hauv metallurgy, hluav taws xob, kev lag luam tshuaj lom neeg, roj av, thee, cement thiab lwm yam kev lag luam. Hauv kev ua haujlwm tsuas, nws yog siv dav hauv cov txheej txheem xa cov tailings hauv qhov av, rov qab ua qhov av thiab lwm yam kev lag luam. Tshwj xeeb, cov yeeb nkab no zoo heev rau kev xa cov kub ntawm -50 ° C txog + 150 ° C, uas yooj yim hnav thiab xeb. Peb tuaj yeem ua kom tuab ntawm lub ces kaum yeeb nkab raws li qhov xav tau ntawm cov neeg siv khoom, yog li ua kom lub neej ua haujlwm ntev dua. Lub caij no, lub neej ua haujlwm ntawm cov yeeb nkab hlau uas muaj roj hmab tuaj yeem ncav cuag 15-40 xyoo feem ntau. Cov yeeb nkab tuaj yeem tig yuav luag 90 degrees tom qab 6-8 xyoo ntawm kev pabcuam. Txhua zaus tig tuaj yeem ua kom lub neej ua haujlwm ntev dua, cov yeeb nkab hlau tuaj yeem raug khi nrog roj hmab ntau zaus peb txog plaub zaug, yog li nws txo qis kev siv nyiaj ntxiv.
