Ibhola le-alumina elimelana ne-Microcrystalline abrasion liyindlela yokugaya yekhwalithi ephezulu, eyenziwe ngezinto ezikhethiwe ezithuthukisiwe, ubuchwepheshe bokubumba obuthuthukisiwe, futhi ibalwe kuhhavini lomhubhe onezinga eliphezulu lokushisa.Lo mkhiqizo unokuminyana okuphezulu, ubulukhuni obukhulu, ukuguga okuphansi, ukuzinza okuhle kokuzamazama komhlaba kanye nokumelana nokugqwala okuhle.Iyindawo ekahle kakhulu yokugaya okucwebezelayo, amabhilidi kanye nezimpushana zamaminerali, futhi isetshenziswa njengendawo yokugaya izigayo zamabhola e-ceramic kanye nosimende., Izindwangu, ama-refractories, i-inorganic mineral powder kanye nezinye izimboni.
