bauxite abrasive

Calcined in a rotary kiln at temperatures above 1600°C to achieve maximum density and hardness. Our Bauxite has a Polished Stone Value (PSV) > 70 and is the smallest. Al2O₃ content is 87%.

Superior Polished Stone Value (PSV > 70)
High Alumina, High Density
Application-Specific Gradations

Grain Sizes: Available in standard ranges including 0-1mm, 1-3mm, 3-5mm, 5-8mm, and finer mesh options (e.g., #8/16 to #120/270). Custom sizes available upon request for specific needs.
Standards Compliance: FEPA for grit sizing; ASTM-tested for abrasion resistance; EN-compliant for safety in anti-skid applications; ISO 9001 for manufacturing quality.
Customization: Tailored to regional preferences, such as coarser grains for heavy blasting or finer for precision polishing, ensuring compatibility with international equipment standards.
