Leben alumina oo sare waxaa laga sameeyaa bauxite chamotte oo la xushay oo ah walax ceeriin ah oo ugu weyn, waxaana lagu shidaa heerkul ah 1450-1470°C iyadoo la adeegsanayo hab horumarsan oo leh xakamayn tayo adag. Lebenada Dabka Alumina ee Sare waxaa lagu sameeyaa alumina ama walxo kale oo ceeriin ah oo ka kooban alumina oo sare iyada oo loo marayo qaabaynta iyo dab-shidka. Sababtoo ah qaabkeeda dhexdhexaadka ah ee ka-hortagga alumina waxay u adkaysan kartaa iska caabbinta nabaad-guurka aashitada.
Habka Lebenka Alumina Sare
Ka gudub Xulashada oo shaandhee chamotte si aad u nadiifiso birta ka hor intaadan jabin, taas oo hagaajin karta tayada lebenka alumina ee sare. Sababtoo ah waxaa jira saami sare oo ka mid ah grog-ka ku jira maaddooyinka oo gaari kara 90-95%. Dooro oo hubi in grog-ku uu burburo.
Saddex darajo oo ah leben Alumina Sare ah
Sida laga soo xigtay Al2O3 kala duwan, lebenka alumina ee sare waxaa loo kala saari karaa Saddex Darajo Shiinaha.
Lebennada Alumina Sare ee Heerka I waxay leeyihiin in ka badan 75% maadada Al2O3.
Lebennada Alumina Sare ee Fasalka II waxay leeyihiin 60 ~ 75% maadada Al2O3.
Lebennada Alumina Sare ee Heerka III waxay leeyihiin 48 ~ 60% maadada Al2O3.
Astaamaha Lebenka Alumina Sare
Lebenka aluminiumka sare wuxuu leeyahay astaamo wanaagsan sida waxqabadka heerkulka sare, daxalka weyn iyo iska caabbinta xirashada, cufnaanta badan ee badan, maadada birta oo hooseysa, iwm.
