Emikhakheni yezimayini, usimende, ukukhiqizwa kukagesi, kanye nobunjiniyela bemishini esindayo, ukuguguleka kwezingxenye zemishini kuholela ngqo ekunciphiseni ukusebenza kahle kokukhiqiza kanye nokwanda kwezindleko zokulungisa. Njengesixazululo sokulwa nokuguguleka esisebenza kahle kakhulu, i-liner ye-alumina ceramic dimple engagugi yandisa kakhulu impilo yesevisi yemishini ngomklamo wayo wesakhiwo esihlanganisiwe. Ngokuvamile ekhiqizwa nge-alumina ehlanzekile kakhulu (Al₂O₃) enokuqukethwe okungu-≥92%, lawa ma-liners ashiswa kusetshenziswa inqubo yokucindezela okomile okushisa okuphezulu, okuholela ekuxineni okuphezulu kanye nesakhiwo esincane esifanayo.
Ubuchwepheshe obuyinhloko balo mkhiqizo busekuklanyweni kwawo kobuso bejometri “be-dimple” noma “be-bump” kanye nezakhiwo zomzimba ezithembekile. Isakhiwo se-dimple sandisa ngempumelelo ingcindezi yokuxhumana phakathi kwezinto kanye nobuso be-liner, okusiza ukuphula ifilimu yomoya phakathi kwezinto nodonga ezinhlelweni zokuhambisa noma zokuthutha, ngaleyo ndlela kuthuthukiswe ukugeleza kwezinto futhi kuvimbele ukunamathela. Ngokuphathelene nedatha yokusebenza, i-92% ye-alumina ceramic ivame ukufeza ubunzima be-Rockwell (HRA) obungaphezu kwama-80, ubukhulu obungu-≥3.6 g/cm³, futhi ukumelana kwayo nokuguguleka kuphindwe izikhathi ezingu-15 noma ngisho nangaphezulu kunokwensimbi yendabuko ye-manganese ephezulu. Ngaphezu kwalokho, izinto ze-ceramic ze-alumina ephezulu zinikeza ukumelana okuhle kakhulu kokushisa okuphezulu kanye nokumelana nokugqwala, okuzivumela ukuthi zivumelane nezimo zokusebenza eziyinkimbinkimbi zezimboni.
Ezinhlelweni ezithile ngaphakathi kwemishini yobunjiniyela, ama-dimple liner asetshenziswa kabanzi ekubambeni ama-pulley kuma-conveyor ebhande, ama-chute, ama-hopper, kanye nama-lining okugaya. Inqubo yokufaka ithinta ngqo umphumela wokuvikela; izinyathelo ezibalulekile zifaka: ukubhula ngesanti ebusweni besisekelo (ukufeza ukuhlanzeka kwe-ISO Sa2.5), ukusebenzisa ngokufana i-polymer adhesive enezingxenye ezimbili (ukulawula ukujiya kube yi-1-2mm), kanye nokubopha okuhlanganisiwe kwama-liners ukuqinisekisa ukusatshalaliswa kokucindezeleka. Ngenxa yokuthi ingemuva lawo livame ukwakhiwa ngemifantu noma izikhala ze-dovetail, ama-dimple liner akha i-mechanical lock ne-adhesive, enikeza ukumelana okuqinile ekuqhekekeni ngaphansi komthelela wezinto ezisheshayo.
Ngamafuphi, ukusetshenziswa kweama-liner e-alumina ceramic dimple angagugikuyisinqumo esingabizi futhi esithembekile sokufeza ukuvikelwa kwesikhathi eside kwemishini yobunjiniyela. Ayigcini nje ngokumelana nokuguguleka kwezinto ezibonakalayo ngenxa yobunzima obukhulu kodwa futhi ithuthukisa ukusebenza ngokusebenzisa i-geometry ephezulu yobuso. Kumabhizinisi afuna ukuzinza kokusebenza kanye nezindleko zokusebenza ezincishisiwe, ukukhetha imikhiqizo kubakhiqizi abadumile abahlangabezana nezimfuneko zobuchwepheshe (njengokuqukethwe kwe-Al₂O₃, ubulukhuni, kanye nokumuncwa kwamanzi) kanye nokunamathela ezinqubweni zokufaka ezijwayelekile kubalulekile ekuqinisekiseni ukuvikelwa kokuguguleka okusebenzayo.
