Lub vijtsam yog ib qho ntawm cov khoom siv hauv asphalt sib xyaw cog thiab tuaj yeem pab tshuaj ntsuam cov ntaub ntawv. Txawm li cas los xij, qhov mesh qhov ntawm qhov screen feem ntau raug thaiv thaum lub sijhawm ua haujlwm. Kuv tsis paub tias qhov no yog vim qhov screen lossis cov khoom siv. Peb yuav tsum paub thiab tiv thaiv nws.

Tom qab soj ntsuam thiab txheeb xyuas cov txheej txheem kev ua haujlwm ntawm asphalt mixing cog, nws tuaj yeem txiav txim siab tias qhov txhaws ntawm qhov screen yog tshwm sim los ntawm qhov me me ntawm qhov screen. Yog tias cov khoom siv me me loj dua, lawv yuav tsis tuaj yeem dhau los ntawm qhov screen qhov smoothly thiab blockage yuav tshwm sim. Ntxiv rau qhov no, yog cov pob zeb uas muaj cov pob zeb loj lossis cov kab zoo li rab koob nyob ze rau ntawm qhov screen, qhov screen qhov yuav txhaws.
Nyob rau hauv cov ntaub ntawv no, cov pob zeb chips yuav tsis raug tshuaj xyuas, uas yuav cuam tshuam rau qhov sib xyaw ntawm cov khoom sib tov, thiab thaum kawg ua rau qhov zoo ntawm asphalt tov khoom 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 braided nrog lub taub tuab tuab, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws
