Brown Corundum

Brown Corundum is made from high-quality bauxite by fusing in a tilt-pour electric are furnace at a high temperature of 2000 °C. It is processed with cone crusher and Barmac crusher by the dressing. Magnetic-separating and screeing. The crystallized ingot becomes grains of high density and hardness. Good self-sharpening and excellent alumina is grinding properties. The grains are in a blocky shape. Brown corundum is suitable for manufacturing vitrified and resinoid tools. Lapping, polishing, and blasting. It also may be used as superior refractories.
