Iilayini yerabha ye-alumina ceramic engagugiyosisixhobo esidityanisiweyo esisetyenziswa kakhulu kwicandelo lokukhusela ukuguguleka kwemizi-mveliso. Yandisa ubomi benkonzo yezixhobo phantsi kweemeko ezinzima ngokudibanisa ukumelana nokuguguleka okuphezulu kwe-alumina ceramic kunye neempawu zerabha zokuthambisa. Le liner isebenzisa i-alumina njengesixhobo esiphambili, kunye nokongezwa komgubo we-ceramic kunye ne-silicon oxide, etshiswe kubushushu obuphezulu malunga ne-1700°C. Umxholo wayo we-alumina ngokubanzi awukho ngaphantsi kwe-95%, ubuninzi bufikelela kwi-3.5-3.9 g/cm³, kwaye ubunzima beRockwell buphezulu njenge-HRA85-90, okuqinisekisa ukumelana nokuguguleka okuhle. Kwizicelo ezisebenzayo, le liner ibonisa isakhiwo esidityanisiweyo esinee-layer ezininzi: umaleko ophezulu yi-alumina ceramic, ophakathi ngumaleko werabha, kwaye ezantsi yipleyiti yentsimbi exhasayo. Ezi layer zintathu zibotshelelwe ngokuqinileyo ngenkqubo ye-vulcanization, zenza inkqubo yokukhusela ukuguguleka edibeneyo.
Ukusebenza okugqwesileyo kwale liner edibeneyo kubonakala kwiinkalo ezininzi: Okokuqala, ukumelana kwayo nokuguguleka kugqwesileyo, ubunzima be-alumina corundum ceramic bufikelela ngaphezulu kwe-HRA85, kwaye ukumelana nokuguguleka kungaphezulu kwama-200 kunokwentsimbi eqhelekileyo yekhabhoni. Okwesibini, imveliso inokumelana okuhle nempembelelo. Ngefomula ye-ceramic eqinileyo kunye noyilo oluyindilinga olulodwa, kunye nomaleko we-rubber buffer, inokumelana ngempumelelo nempembelelo yezinto ezinkulu. Okwesithathu, i-liner inokumelana okuhle nobushushu kwaye inokusebenza ngokuzinzileyo kuluhlu lobushushu oluphakathi kwe-0°C ukuya kwi-250°C ixesha elide. Ukongeza, umaleko werabha usebenzisa ifomula ekhethekileyo enokumelana ne-asidi kunye ne-alkali, ekwaziyo ukumelana nokugqwala kwiindawo ezibuthathaka ze-asidi kunye ne-alkali ebuthathaka. Ngokuphathelele iipropati zomzimba, amandla okucinezela e-liner yi-≥850 MPa, ubulukhuni bokwaphuka yi-KΙC ≥4.8 MPa·m1/2, amandla okubopha phakathi kwerabha kunye ne-ceramic (uxinzelelo lwe-shear) yi-≥3.0 MPa, kwaye ubomi bokuguga kwerabha yi-≥15 iminyaka, okuqinisekisa ukuthembeka kwexesha elide kwemveliso.
Iiliner zerabha ze-alumina ceramic ezingagugiyo zisetyenziswa kakhulu kwiindawo zoshishino, ikakhulu kubandakanya iinkqubo zokuhambisa amalahle ombane, ii-hopper zezityalo zentsimbi, ii-chutes zemigodi, izixhobo zokuhlamba amalahle, iinkqubo zokuhambisa izityalo zesamente, kunye nezinye iindawo ezigugileyo kakhulu. Kwiindlela ezisebenzayo, iiliner ngokubanzi zahlulwe zibe ziintlobo ezahlukeneyo ezifana ne-bonded, welded, kunye ne-rubber composite, kubandakanya iinkcukacha ezahlukeneyo ezifana ne-rectangular eqinileyo, enemingxuma ejikelezileyo, kunye neepayipi ze-trapezoidal. Zingasikwa kwaye zigotywe ngokwemilo yezixhobo, ukuhlangabezana neemfuno zokufakela izixhobo ezimile ngokukodwa. Uyilo lwemodyuli lwenza kube lula ukufakwa nokutshintshwa, kunciphisa kakhulu ixesha kunye neendleko zokugcina izixhobo. Kwiprojekthi yokuguqula ubuchwepheshe be-green intelligent mining and processing technology ye-4.5 yezigidi zeetoni ye-Dundee Mining, i-grinding bin yamkela iiliner ceramic ezisemgangathweni ophezulu ezinomxholo we-K95 fine alumina ≥95% kunye noxinano ≥3.8 g/cm³, ebonisa ukuthembeka kwayo kwiiprojekthi zoshishino ezinkulu.
