Alumina yoyera yosakanikiranandipo alumina wofiirira wosakanikirana ndi zinthu ziwiri zofala zomwe zimagwiritsidwa ntchito kwambiri. Anthu ambiri sadziwa kusiyana kwachindunji pakati pa ziwirizi kupatula mtundu wake. Tsopano ndikukuphunzitsani kuti mumvetse.
Ngakhale kuti ma abrasives onsewa ali ndi alumina, kuchuluka kwa alumina mu alumina yoyera yosakanikirana ndi kopitilira 99%, ndipo kuchuluka kwa alumina mu alumina yofiirira yosakanikirana ndi kopitilira 95%.
Alumina yoyera yosakanikiranaimapangidwa kuchokera ku ufa wa alumina, pomwe alumina yofiirira yokhala ndi ma flakes a anthracite ndi iron, kuphatikiza bauxite yokhala ndi calcined. Alumina yoyera yokhala ndi kuuma kwakukulu imagwiritsidwa ntchito ndi ogwiritsa ntchito ena apamwamba, chifukwa imakhala ndi mphamvu yabwino yodulira komanso kupukuta bwino, ndipo imagwiritsidwa ntchito kwambiri pa chitsulo cha carbon, chitsulo cha alloy, chitsulo chopangidwa, bronze wolimba, ndi zina zotero. Gwiritsani ntchito alumina yoyera yokhala ndi ma flakes kuti mupukute bwino komanso mowala,
Alumina yofiirira yosakanikirana imagwiritsidwa ntchito pamsika waukulu, ndipo imagwiritsidwa ntchito kwambiri pazitsulo zozimitsidwa, zitsulo zothamanga kwambiri, ndi zitsulo zokhala ndi mpweya wambiri kuti zichotse ma burrs pamwamba, ndipo mphamvu yopera siili yowala ngati ya alumina yoyera yosakanikirana.
