Brown Fused Alumina (BFA) is a tough, durable synthetic abrasive made from bauxite. DOMILL provides abrasive grains with varying bulk density, particle size, and chemical composition to meet the needs of industries such as grinding wheels, sandpaper manufacturing, sandblasting, and refractory materials.
DOMILL uses high-purity bauxite as the raw material for production.
By precisely controlling the smelting temperature, time, and furnace atmosphere, we manage the variation in chemical composition.
The final abrasive grains are crushed and graded according to strict requirements, resulting in high-purity and chemically stable brown fused alumina abrasive particles.
Grinding & Cutting Wheels – Used in manufacturing durable and precise grinding tools.
Abrasive Blasting – Perfect for tough surface cleaning and preparation.
Polishing & Finishing – Offers smooth, uniform results for polishing.
Refractory Materials – Withstands high temperatures, making it suitable for heat-resistant materials.
