Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.
The calcined bauxite can be processed into bauxite sand and bauxite powder of different particle sizes, both of which can be directly used as refractory sand. It has a very high status in the field of refractory materials.

1. High grade bauxite is one of the main raw materials in the welding flux industry.
Welding flux grade bauxite powder is mainly selected after calcination corresponding content of granular bauxite grinding screening, removal of impurities, the formation of the corresponding content and particle size requirements of fine powder.
2. Precision casting. The bauxite clinker is processed into fine powder to form a mold and then precision cast.
3. Aluminum silicate refractory fiber. Light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical vibration resistance.
4. Using magnesia and bauxite clinker as raw materials, adding appropriate binders, the effect is very good for castables.
5. Manufacturing high alumina refractory cement.
1. Own testing and quality control laboratory to provide technical support.
2. Exclusive cooperation minerals, providing stable quality and high purity bauxite resources.
3. Guaranteed production capacity, with 3000 tons monthly.
4. Customized different alumina content and particle size according to different customer needs.
5. Provide third-party test report.
