Ii-liner yerabha ye-alumina ceramic engagugiiyinto ehlanganisiwe esetshenziswa kabanzi emkhakheni wokuvikela ukugqokwa kwezimboni. Yandisa ngempumelelo impilo yesevisi yemishini ngaphansi kwezimo ezinzima ngokuhlanganisa ukumelana okuphezulu kokugqokwa kwe-alumina ceramic kanye nezakhiwo zokubopha zerabha. Le liner isebenzisa i-alumina njengezinto eziyinhloko zokusetshenziswa, ngokwengeza i-ceramic powder kanye ne-silicon oxide, eshisiwe emazingeni okushisa aphezulu cishe ngo-1700°C. Okuqukethwe kwayo kwe-alumina ngokuvamile akungaphansi kwama-95%, ubuningi bufinyelela ku-3.5-3.9 g/cm³, kanti ubulukhuni beRockwell bufinyelela ku-HRA85-90, okuqinisekisa ukumelana okuhle kokugqokwa. Ezisetshenzisweni ezisebenzayo, le liner ibonisa isakhiwo esihlanganisiwe esinezingqimba eziningi: ungqimba olungaphezulu luyi-alumina ceramic, oluphakathi luyingqimba yerabha, kanti phansi luyipuleti lensimbi elisekelayo. Lezi zingqimba ezintathu ziboshwe ngokuqinile ngenqubo ye-vulcanization, zakha uhlelo lokuvikela ukugqokwa oluhlanganisiwe.
Ukusebenza okuvelele kwale liner ehlanganisiwe kubonakala ezicini eziningi: Okokuqala, ukumelana kwayo nokuguguleka kuhle kakhulu, njengoba ubulukhuni be-alumina corundum ceramic bufinyelela ngaphezu kwe-HRA85, kanti ukumelana nokuguguleka kungaphezu kokuphindwe izikhathi ezingu-200 kunokwensimbi evamile yekhabhoni. Okwesibili, umkhiqizo unokumelana okuhle komthelela. Ngefomula ye-ceramic eqinile kanye nomklamo oyingqayizivele oyindilinga, kuhlanganiswe nesendlalelo se-raber buffer, ingamelana ngempumelelo nomthelela wezinto ezinkulu. Okwesithathu, i-liner inokumelana okuhle kokushisa futhi ingasebenza ngokuzinzile ngaphakathi kobubanzi bokushisa obuphakathi kuka-0°C no-250°C isikhathi eside. Ngaphezu kwalokho, isendlalelo serabha sisebenzisa ifomula ekhethekile enokumelana kwe-asidi ne-alkali, ekwazi ukumelana nokugqwala ezindaweni ezibuthakathaka ze-asidi ne-alkali. Ngokuphathelene nezakhiwo zomzimba, amandla okucindezela e-liner angama-≥850 MPa, ukuqina kokuphuka kwe-KΙC ≥4.8 MPa·m1/2, amandla okubopha phakathi kwerabha ne-ceramic (ukucindezeleka kwe-shear) angama-≥3.0 MPa, kanti impilo yokuguga kwerabha engama-≥15 iminyaka, okuqinisekisa ukuthembeka kwesikhathi eside komkhiqizo.
Ama-liner enjoloba e-alumina ceramic amelana nokuguguleka asetshenziswa kabanzi emikhakheni yezimboni, ikakhulukazi okuhlanganisa izinhlelo zokuhambisa amalahle asebenza ngomlilo, ama-hopper ezitshalo zensimbi, ama-chute ezimayini, imishini yokuwasha amalahle, izinhlelo zokuhambisa izitshalo zesamente, kanye nezinye izindawo ezigugile kakhulu. Ezisetshenzisweni ezisebenzayo, ama-liner ngokuvamile ahlukaniswe ngezinhlobo ezahlukene njenge-bonded, welded, kanye ne-rubber composite, okuhlanganisa imininingwane ehlukahlukene njengonxande oqinile, onezimbobo eziyindilinga, namapayipi e-trapezoidal. Angasikwa futhi agotshwe ngokwesimo semishini, ahlangabezane nezidingo zokufaka imishini enomumo okhethekile. Umklamo we-modular wenza kube lula ukufakwa nokufakwa esikhundleni, okunciphisa kakhulu isikhathi sokugcinwa kwemishini kanye nezindleko. Kuphrojekthi yokuguqulwa kobuchwepheshe bokumba nokucubungula okuluhlaza okungamathani ayizigidi ezingu-4.5 ye-Dundee Mining, i-grinding bin yamukele ama-liner e-ceramic asezingeni eliphezulu anokuqukethwe kwe-alumina encane ye-K95 ≥95% kanye nobuningi ≥3.8 g/cm³, okubonisa ukuthembeka kwawo kumaphrojekthi amakhulu ezimboni.
