Nyob rau hauv lub teb chaws kiln daim ntaub ntawv, qhov ntau tshaj plaws ntawm tus cement kev lag luam. Kev sib xyaw tseem ceeb ntawm cov cement yog sau ua "ob txoj kev sib tsoo thiab ib qho kub nyhiab", ntawm cov uas "hlawv ib qho" txhais tau tias yog cov txheej txheem ntawm cov khoom siv hlawv tom qab sib tsoo thiab sib tsoo rau clinker nyob rau hauv qhov siab ntawm lub ntsuas phom. Yog li ntawd, cov kiv kom tov yog cov tswv tsev ntawm cov pob zeb ntau lawm, feem ntau hu ua cov koom haum cement "plawv." Hauv cov khoom siv hauv kev lag luam, lub pob kiln yog siv los ua kom cov av nplaum, limestone thiab slag rau ziab ntxiv nrog rau calcining cement clinker. Nyob rau hauv cov khoom ntawm refractory cov ntaub ntawv, lub rot kiln yog siv los hlawv raw khoom kom lawv ruaj khov loj thiab nce hauv zog. Ua molding. Cov hlau, hlau, hlau, zinc, tin, tooj liab, tungsten, chromium thiab cov ntaub ntawv yog sintered thiab teb kiln rau smelting khoom rau sinter thiab roast ore, mloog zoo thiab nruab nrab.
Raws li kev tiv thaiv ib puag ncig, tsim cov teb chaws hauv lub ntiaj teb siv siv cement kilns mus hlawv cov khib nyiab thiab khib nyiab rau ntau tshaj 20 xyoo. Qhov no tsis tsuas yog txo thiab ua kom tsis txhob muaj cov khib nyiab, tiam sis tseem siv cov khib nyiab li roj kom txuag tau nyiaj thiab khib nyiab.
YOGIE tuaj yeem npaj cov khoom seem rau cov ntsia hlau ua teb, xws li lub cav log ntawm lub cav, lub cav kiln iav nplhaib, cov kev pabcuam rau cov menyuam hnyav thiab cov ncej, thiab lwm yam.
