Lub raj zeb zeb yog ib qho cuab yeej tseem ceeb hauv kev ua hlau. Nws ua haujlwm los hloov cov ntawv hlau lossis coils rau hauv cov raj. Lub hauv paus ntsiab lus tseem ceeb yog tias cov hlau Tshuag tau dhau los ntawm cov txheej txheem ntawm cov menyuam yaus uas maj mam khoov thiab ua kom nws ua tiav kom txog rau thaum daim ntawv tubular tiav.
Cov mills no hloov tau thiab tuaj yeem ua haujlwm nrog ntau yam hlau xws li stainless hlau thiab tooj dag. Lawv tuaj yeem tsim cov raj nrog ntau txoj kab uas hla thiab qhov ntev, ua tiav cov kev xav tau ntawm ntau yam kev lag luam xws li lub zog thiab kev tsim khoom.
Txawm li cas los xij, tube mills muaj lawv cov kev txwv. Kev teeb tsa thiab kev hloov kho ntawm cov rollers xav tau kev txawj ntse. Kev teeb tsa tsis raug tuaj yeem ua rau cov raj tsis sib haum nrog cov phab ntsa tuab lossis qhov chaw tsis zoo. Tsis tas li ntawd, cov tshuab yuav tsum muaj kev saib xyuas niaj hnub los tiv thaiv kev hnav thiab tsim kua muag thiab ua kom muaj kev ua haujlwm tsis tu ncua.
Hauv kev xaus, thaum lub raj mills muaj peev xwm ua tau zoo rau kev tsim cov raj zoo, kev ua haujlwm zoo thiab kev saib xyuas yog qhov tseem ceeb heev kom kov yeej cov teeb meem cuam tshuam thiab siv tag nrho lawv cov peev xwm hauv cov txheej txheem tsim khoom.
