Ihlukaniswe yaba izigaba ezintathu: amaholoholo, medium and enemininingwane.Imeshi emahhadla ibomvu ngokumnyama, i-mesh emaphakathi ibomvu ngokukhanyayo, kanti inetha elihle libomvu nokumhlophe.Usayizi wokusanhlamvu wemeshi ngayinye ufana, futhi ukwakheka okusanhlamvu kufana.Ibizwa ngokuthi i-angular crystal enemiphetho ebukhali namandla okugaya aphezulu.

Okokugaya imabula nezinye izinto ezithambile embonini yamatshe.

Imboni yengilazi igaya ama-glass burrs, amashubhu ezithombe zikamabonakude, amathuluzi okubona, amalensi, amaprism, ingilazi yewashi, njll.

I-Metal industrial sandblasting, derusting, grinding.Imboni yokunyathelisa igaya i-offset plate, futhi imboni yokukhanya icubungula isampula yepulasitiki, isikhumba, i-sandpaper nokunye okusebenzisayo.

Amandla okugaya e-corundum yemvelo aphansi kancane kunalawo e-corundum emhlophe yesithando somlilo, kodwa ukuqina kwawo kunamandla, futhi anezici zengxenye efana negobolondo.Izinzuzo zayo ukushelela okuphezulu kwezingxenye zokugaya, amamaki esihlabathi amancane futhi angashoni.Indawo yokugaya ilungile futhi ifana, engathuthukisa ikhwalithi yomkhiqizo, okuyisici esiyingqayizivele salo mkhiqizo.I-emery yemvelo inesikhathi esifushane sokugaya, ukusebenza kahle okuphezulu kanye nenani eliphansi, elingenza ukushoda kwempilo yesevisi emfushane.
