Product Description
High-quality Aluminum Bauxite Refractory Raw Material (Al2O3 85-88%)
Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process removes moisture and enhances the high alumina content, refractoriness, and grain hardness.
- Strict sorting and high sintering temperature for a dense structure.
- Low impurity levels and full reaction during processing.
- Customizable aggregates and powder based on specific industrial requirements.
