Cement Mixer:
MAAs tov khoom yog ib hom tshuab lossis cov cuab yeej tsim tshwj xeeb rau kev sib xyaw cov cement, uas yog ib qho tseem ceeb ntawm cov khoom siv hauv kev ua vaj tse. Cement, nyob rau hauv nws cov hmoov qhuav qhuav, yog tov nrog lwm cov ntaub ntawv xws li aggregates (xuab zeb thiab gravel) thiab dej los tsim pob zeb.

Lub pob zeb sib tov, ntawm qhov tod tes, yog lub tshuab ntau yam tsim los sib tov tag nrho cov khoom ntawm pob zeb, suav nrog cov cement, aggregates (xuab zeb thiab gravel los yog crushed pob zeb), thiab dej. Cov khoom sib xyaw ua ke muaj peev xwm tuav tau cov pob zeb ua tiav, uas ua rau tsim cov pob zeb ntub dej npaj rau kev tso kawm.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb yog tias cov cement tov khoom yog tsim tshwj xeeb rau kev sib xyaw cov cement qhuav nrog lwm cov ntaub ntawv qhuav, thaum lub pob zeb sib tov yog tsim los tswj cov khoom tiav, nrog rau cov pob zeb ntub dej. Thaum tib neeg feem ntau xa mus rau "cement mixer," lawv feem ntau txhais tau tias yog lub pob zeb sib tov, vim nws yog lub tshuab siv los tsim pob zeb rau kev tsim kho thiab lwm yam kev siv.
