Modular conveyor txoj siv yog tsim los ntawm cov qauv uas muaj cov tav tav, txhua tus nyob rau hauv daim ntawv ntawm textured sab sauv qaum qauv nyob rau hauv ib tug elongated tav puag. Cov tav sib law liag yog sib nrug deb tom qab ntawm sab saum toj ntawm cov modules. Longitudinal slots ntawm lateralally consecutively ribs lees cov ntiv tes ntawm kev hloov daim hlau rau kev sib hloov ntawm cov khoom ntawm thiab tawm ntawm txoj siv. Cov qauv kev ntxhib los mos muaj xws li kab ntawm cov hniav, truncated pyramids los yog cones, corrugated qauv, thiab sinuous hlaws dai rau saum cov khoom uas tau txais kev txhawb nqa me ntsis hauv cov dej ntub dej.
