Product details

Model Number: F12-F240 Brand Name: lyhuayun Key Specifications/Special Features: Calcined bauxite is one of the principal ore of aluminumCalcined bauxite contains hydrous aluminum oxides and aluminum hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areasCalcined bauxite is obtained by calcining (heating) superior grade bauxite at high temperature (from 85OC to 1600C)This removes moisture thereby increasing the alumina contentCompared to an alumina content of about 57% to 58% in raw bauxite, calcined bauxite has an alumina content of 84% to 88%The heating is carried out in rotary kilnsApplication:Calcined bauxite is typically classified according to its intended commercial application, such as abrasive, cement, chemical, metallurgical and refractoryAs raw material for use in high alumina and super duty refractory bricks and shapes, plastics, castable refractory, motors, ramming mixes, abrasive grains and other productsCalcined bauxite is widely used in:
1. Aluminium metallurgy
2. Refractory material
3. Precision casting
4. Aluminate cement
