Lub vijtsam yog ib qho ntawm cov khoom sib xyaw ntawm asphalt mixing chaw nres tsheb, uas tuaj yeem pab cov khoom siv los soj ntsuam, tab sis qhov screen qhov ntawm lub vijtsam feem ntau raug thaiv thaum lub sijhawm ua haujlwm. Kuv tsis paub tias nws yog vim qhov screen lossis cov khoom siv, yog li kuv yuav tsum nrhiav thiab tiv thaiv nws.
Tom qab soj ntsuam thiab txheeb xyuas cov txheej txheem ua haujlwm ntawm asphalt mixing chaw nres tsheb, nws tuaj yeem txiav txim siab tias qhov thaiv ntawm lub qhov screen yog tshwm sim los ntawm qhov me me ntawm qhov screen. Yog tias cov khoom siv me me loj dua, lawv tsis tuaj yeem hla lub qhov screen kom du, ua rau muaj kev thaiv. Ntxiv rau qhov no, yog tias muaj cov pob zeb loj lossis ntau lub pob zeb zoo li rab koob los ze rau qhov screen, qhov screen qhov tseem yuav raug thaiv.
Nyob rau hauv rooj plaub no, cov pob zeb chips yuav tsis tuaj yeem raug tshuaj xyuas, uas yuav cuam tshuam rau qhov sib xyaw ntawm cov khoom sib xyaw, thiab thaum kawg ua rau qhov zoo ntawm cov khoom sib xyaw asphalt tsis ua raws li qhov yuav tsum tau ua. Txhawm rau kom tsis txhob muaj qhov tshwm sim no, sim siv lub vijtsam steel hlau woven nrog cov kab tuab tuab, txhawm rau txhawm rau txhim kho qhov dhau ntawm qhov screen qhov thiab xyuas kom zoo ntawm asphalt.
