Umaleko osebenzayo oyintloko we-alumina ceramic-resistant wear tee yi-ceramic lining eyenziwe nge-high-purity alumina (α-Al₂O₃). Le nto inesakhiwo sekristale esizinzileyo se-corundum, esinobunzima obufikelela kwi-HRA 85 okanye ngaphezulu (ubunzima beVickers HV 1000-1600) kunye noxinano lwe-3.6-3.9 g/cm³. Umsebenzi oyintloko we-alumina ceramic lining kukumelana nokukhukuliseka okukhulu kwamasuntswana aqinileyo kwiindawo zokuphambuka kunye nokudibanisa imibhobho. Ukumelana kwayo nokuguguleka kuye kwavavanywa elebhu ukuba kuphindwe ka-266 kune-manganese steel kunye ka-171.5 kune-high-chromium cast iron. Idatha yesicelo semizi-mveliso ibonisa ukuba le lining inokwandisa ubomi benkonzo yemibhobho ngaphezu kwamaxesha alishumi. Ngaphezu koko, i-alumina izinzile ngokweekhemikhali kwaye ayithathi cala, inika ukumelana nee-asidi, ii-alkalis, iityuwa, kunye ne-organic media ngaphakathi kobushushu obuthile kunye noxinzelelo.
Ii-alumina ceramic tees zentsimbi ezingagugiyo zisetyenziswa kumacandelo ahlukeneyo emizi-mveliso anxiba kakhulu. Kwiinkqubo zamandla obushushu, zisetyenziswa kwiipayipi ezithwala umgubo wamalahle, kwiinkqubo zokucola, kwiipayipi zokususa uthuthu, nakwiinkqubo zokususa uthuli. Kwishishini lezemigodi, zifanelekile kwiinkonzo zokuthutha udaka, kwiindlela zokuthutha imisele, kwiindlela zokuthutha ezixineneyo, nakwiipayipi zokuthutha amalahle ezicocekileyo kwiindawo zokulungisa amalahle ezinzima. Kwintsimi yesinyithi nentsimbi, zisetyenziswa kwiinkqubo zokususa uthuli lwe-blast furnace, kwiindlela zokuthutha i-slag, nakwiindlela zokuhambisa izinto ngexesha leenkqubo zokunyibilikisa. Kwishishini lesamente, zisetyenziswa kwiinkqubo zokuhambisa umoya kwi-pneumatic meal eluhlaza, i-clinker, kunye ne-fly ash. Kwicandelo leekhemikhali, zifanelekile kwiipayipi ezithwala izinto ezibolayo nezirhabaxa. Kwizikhululo zezibuko, zisetyenziselwa ii-slurry kunye ne-sediment transport. Ukongeza, le mveliso ingasetyenziselwa izicelo ezikhethekileyo ezifana nokuthutha i-aluminium enyibilikisiweyo.
Ngexesha lokukhetha, izinto ezifana neempawu eziphakathi, ubungakanani besuntswana, ubushushu bokuhambisa, kunye ne-engile yempembelelo kufuneka ziqwalaselwe ukuze kuchongwe ubukhulu beleyara yeseramikhi (ngesiqhelo yi-4-20mm), ubumsulwa be-alumina, kunye nendlela yokudibanisa umbhobho wangaphandle (ofakwe i-flanged, welded, njl.njl.). Nangona utyalo-mali lokuqala lwale fitting luphezulu kuneemibhobho zentsimbi eziqhelekileyo, ubomi bayo benkonzo obongezelelekileyo kunye nokunciphisa okukhulu kwexesha lokungasebenzi kunye neendleko zokulungisa kwenza ukuba ibe sisisombululo esingabizi kakhulu kwiimeko ezinzima zokuguguleka kunye nokugqwala.
