Rotary kiln calcined bauxite is obtained by calcining superior grade bauxite at high temperatures (from 850 to 1600) in the rotary kiln. 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 84% to 88%. Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.

As we all know, China is the world's leading supplier of bauxite, producing over three million tons per year for refractory, abrasive, and welding applications. Calcined bauxite is made of excellent bauxite ores, fired in a kiln to impart its superior abrasive qualities, hardness, and long-term frictional resistance. This materials are in stable index, homogeneous structure and excellent high-temperature performance. Its high alumina and low iron make calcined bauxite be the ideal raw material in refractory and abrasive products.

Welding grade bauxite Welding grade bauxite has tight regulation on presence of sulfur and phosphorus which are detrimental to the weld. When present at high concentrations, they induce porosity and cracking, and at lower concentrations, they adversely affect the impact strength of the weld. And moisture for welding grade bauxite should not exceed 0.5% because the potential for any moisture present withthin the flux to reduce to hydrogent, if exposed to a welding arc, the molten weld pool absorbs the hydrogen and will induce brittleness into the weld. Application Welding fluxes are a small but valuable market for calcined bauxite. Techniques for submerged arc welding require the use of a granular flux to shield the molten weld pool rom the atmosphere during the weldâ??s application or pacement. Various proprietary compositions exist and in some cases calcined bauxite is incorportated into these formulations. Calcined bauxite may, in some instances, make up to 25% of the welding flux.

Bauxite is primarily a metallic mineral though it is also used as an industrial mineral. It is the only ore used for large scale aluminium production.Much of the bauxite is formed by the desilication of clays. The alumina-rich components of igneous rocks weather to clay more easily than the mica and chlorite of the phyllites. Bauxite is a product of weathering. The name bauxite is derived from its first study area. It has been classified into laterite and terrarossa types. The laterite type bauxite is formed in situ from crystalline rocks and is rich in gibbsite. The terrarossa type bauxite overlies limestone of dolomite and is rich in bochmite. How do you identify bauxite Bauxite, on the Mohs scale, is usually a mild mineral with a hardness of just 1 to 3. With a pisolitic shape, earthy lustre and a low specific gravity of between 2.0 and 2.5, it is white to grey to reddish brown.
