Calcined Bauxite
Calcined Bauxite manufacturersproduce Calcined Bauxite by firing (heating) the superior grade Bauxite at high temperature (from 850℃ to 1600℃). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 75 % to 90 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 ℃to 1600 ℃ depending upon the customer’s application.CalcinedBauxiteApplications1.Aluminiummetallurgy2.Precisioncasting / Investmentcasting:3.Refractory:highaluminabauxite’srefractorinesscanreach1780°C.4.Aluminiumsilicaterefractoryfiber:Thehighaluminabauxitegrogcanmeltunder2000°C-2200°C intheelectricarcfurnace.Afteraseriesofprocessing,itcanbecomealuminiumsilicaterefractoryfiber,5.Mixingmagnesiaandbauxitegrogwithbinderstopourthemoltensteelladleforbetteroverallliningperformance.6.Producingbauxitecement7.Abrasives8.Ceramicsindustry9.Chemistryindustryforallkindsofaluminiumcompound.Calinced Bauxite Package:By 1 ton jumbo bag
