Mbale yolimba ya alumina ceramic yolimba yosathandi chinthu chopangidwa ndi zinthu zosiyanasiyana zopangidwa ndi alumina ceramic yoyera kwambiri (Al₂O₃ ≥92%) ndi rabara matrix pogwiritsa ntchito njira yotentha yopangira vulcanization. Imaphatikiza kuuma kwakukulu kwa ceramic ndi mphamvu yolumikizira ya rabara, zomwe zimapangitsa kuti ikhale yoyenera kuteteza pamwamba pa zida zamafakitale pansi pa mikhalidwe yokhudza kwambiri komanso yovala kwambiri. Kuuma kwa alumina ceramic layer wamba kumafika pa HRA 85-90, kuchuluka kwake kumakhala kuyambira 3.6 mpaka 3.9 g/cm³, ndipo kukana kwake kuvulala kumakhala pafupifupi nthawi 10 mpaka 15 kuposa mbale wamba zachitsulo.
Makhalidwe ofunikira a ntchito ndi awa: makulidwe a matailosi a ceramic nthawi zambiri amakhala 15-30 mm, makulidwe a rabara 4-15 mm, ndi mphamvu yonse ya peel ≥12 kN/m. Kutentha kwa ntchito kumayambira -40°C mpaka +120°C, ndipo kupirira kwake kwa kanthawi kochepa kumafika 150°C. Kuchuluka kwa kukangana kuli pansi pa 0.2, zomwe zimachepetsa bwino kumatirira kwa zinthu ndi zoopsa zotsekeka panthawi yonyamula. Kudzera mu njira yolumikizirana, kulumikizana kwa mankhwala pa ceramic-raber interface kumalepheretsa kusweka kapena kugawanitsa, zomwe zimawonjezera moyo wautumiki ndi zaka 3-5 poyerekeza ndi zitsulo zachitsulo za manganese.
Ntchito zazikulu zikuphatikizapo: malo osamutsira ma conveyor lamba, ma chute, ndi ma hopper m'mafakitale amigodi ndi ma aggregate; ma chute odyetsera ndi ma separator m'mafakitale achitsulo ndi simenti; ndi machubu otaya malasha m'makina ogwiritsira ntchito malasha amagetsi. Pakuyika, mbale yovunda imakhazikika pa mbale yoyambira ya zida kudzera mu cold bonding kapena hot vulcanization, popanda zomangira zovuta zamakaniko. Pamalo ovalidwa kwambiri, njira yopangira zirconia-toughened composite (Al₂O₃-ZrO₂) ingasankhidwe, kuwonjezera kulimba kwa fracture kufika pa 4.5-5.5 MPa·m¹/², zomwe zimateteza kuwonongeka ndi zinthu zazikulu.
