Kwimveliso yesamente, izixhobo ezifana neepayipi zokuhambisa izinto, iindawo zokwahlulahlula, iinkanyamba, kunye neechutes zinyamezela impembelelo yesantya esiphezulu kunye nokuguguleka okutyibilikayo, okukhokelela ekulahlekelweni ngokukhawuleza kweziseko zesinyithi kunye nokunyuka kweendleko zokulungisa ixesha lokungasebenzi. Ukusetyenziswa kwe-alumina ceramic lining engagugiyo kwandisa ubomi benkonzo. Le lining yenziwa ngokusinta kobushushu obuphezulu, kunye nomxholo we-alumina ongaphantsi kwe-92%, ubuninzi bobuninzi ≥3.60 g/cm³, ubunzima beRockwell (HRA) obungaphezulu kwe-85, kunye nomthamo wokuguguleka ongaphantsi kwe-0.1 cm³ (kuvavanyelwe ngokwe-GB/T 8489-2006).
Xa kuthelekiswa neepleyiti zentsimbi eziqhelekileyo ezingagugiyo (umz., i-NM400), i-alumina ceramic lining ibonakalisa ukumelana nokuguguleka okuphindwe ka-5-8, kunye ne-coefficient ephantsi yokungqubana komphezulu (malunga ne-0.2-0.3 phantsi kweemeko ezomileyo), kunciphisa umngcipheko wokunamathela kwezinto kunye nokuvaleka. Iithayile zeseramikhi zinamathele eludongeni lwangaphakathi lwezixhobo kusetyenziswa i-epoxy resin okanye i-inorganic adhesive, kunye nomlinganiselo wobushushu bokusebenza ukusuka kwi--50°C ukuya kwi-300°C kunye nokunyamezela kwexesha elifutshane ukuya kuthi ga kwi-500°C. Phantsi kweemeko eziqhelekileyo zesityalo sesamente, i-ceramic lining yandisa ubomi benkonzo ye-chute ukusuka kwiinyanga ezi-6 ukuya kwiinyanga ezingaphezu kwama-36.
Olu ngqameko lusetyenziswe ngempumelelo kwiindawo ezibalulekileyo ezifana nee-mill feed chutes, ii-separator guide vanes, ii-cyclone cones, kunye neepayipi zokuhambisa i-clinker kwizityalo zesamente. Idatha yasentsimini ibonisa ukuba phantsi kobukhulu obuqhelekileyo bezinto ezingama-30 mm kunye nesantya esithe ngqo se-15 m/s, emva kweenyanga ezili-12 zokusebenza okuqhubekayo, ubunzulu bokuguguleka kwiitayile zeseramikhi buyi-0.2–0.5 mm kuphela, kwaye amaxesha okugcinwa kwezixhobo andiswa ukuya kuthi ga kwixesha eliphindwe kane kunobude bokuqala. Ifumaneka kwiipleyiti zeseramikhi ezimiselweyo okanye kwiipatches zetayile ze-mosaic, ungqameko luhambelana nezixhobo ezinee-curvature ezahlukeneyo kunye neemilo zesakhiwo.
Ukukhuthazai-alumina ceramic lining engagugiyo kwizixhobo zobunjineli besamentekunciphisa ngokufanelekileyo ukusetyenziswa kwezixhobo ezingasetyenziswayo kunye nokulahleka kwexesha lokungasebenzi, okuphucula amazinga okusebenza ngokubanzi kwimigca yemveliso. Ngexesha lokufakela, qinisekisa ukuba umphezulu wesiseko ucocekile kwaye awunayo ioyile; ixesha lokuncamathelisa elinamathelayo kufuneka lingabi ngaphantsi kweeyure ezingama-24 (kwi-25°C). Kwii-engile zempembelelo ezingaphezulu kwama-45° kwiindawo zokuwa kwezinto, kucetyiswa ukuba kubekho umaleko we-buffer ukuze kuphuculwe ngakumbi ukumelana nempembelelo. Le teknoloji ifakwe kwimigangatho emininzi yoyilo lokukhusela ukuguguleka kwishishini lesamente.
