Kauv conveyor yog cov cuab yeej siv tshuab uas siv lub tshuab hluav taws xob los tsav lub kauv kom tig thiab thawb cov ntaub ntawv kom ua tiav lub hom phiaj ntawm kev xa khoom. Nws tuaj yeem thauj tau horizontally, obliquely lossis vertically, nrog rau qhov zoo ntawm cov qauv yooj yim, me me hla ntu ntu, kev sib khi zoo, kev ua haujlwm yooj yim, kev saib xyuas yooj yim, thiab kev thauj mus los yooj yim. Kauv conveyors muab faib ua ob hom nyob rau hauv cov nqe lus ntawm conveying daim ntawv: axial kauv conveyors thiab shaftless kauv conveyors. Lawv kuj tau muab faib ua U-shaped kauv conveyors thiab tubular kauv conveyors raws li qhov pom. Axial ntsia hlau conveyor yog tsim rau cov ntaub ntawv tsis khov qhuav hmoov thiab cov khoom me me (piv txwv li: cement, ya tshauv, txiv qaub, nplej, thiab lwm yam) thiab cov ntsia hlau tsis muaj cov ntsia hlau yog tsim rau cov khoom siv uas khov thiab yooj yim entangled. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov ntsia hlau conveyor (xws li sludge, biomass, khib nyiab, thiab lwm yam) yog tias cov rotating kauv hniav thawb cov khoom thiab thauj nws. Lub zog uas tiv thaiv cov khoom los ntawm kev sib hloov ua ke nrog cov kauv conveyor hniav yog qhov hnyav ntawm cov khoom nws tus kheej thiab kev sib txhuam ntawm cov ntsia hlau conveyor vaj tse rau cov khoom.
Cov kauv hniav welded rau ntawm lub rotating ncej ntawm cov ntsia hlau conveyor muaj ntau hom nto nyob ntawm seb cov khoom conveyed, nrog rau cov khoom nto, hom siv nto, thiab hniav nto hom. Cov ntsia hlau ncej ntawm cov ntsia hlau conveyor muaj cov kabmob thrust ntawm qhov kawg ntawm cov khoom siv txav mus los muab cov tshuaj tiv thaiv axial rau cov ntsia hlau nrog rau cov khoom siv. Thaum lub tshuab ntev ntev, yuav tsum tau ntxiv cov kabmob nruab nrab ncua kev kawm.
