Brown fused alumina is made from high quality bauxite by fusing in a tilt-pour fixed electric arc furnace, processed with cone crusher and barmac crusher by dressing, magnetic-separation and screening, the crystallized ingot becomes grains of high density and hardness, good self-sharpening and excellent alumina grinding properties. The grains are in blocky shape. Brown fused alumina is suitable for manufacturing vitrified and resinoid tools, lapping, polishing and blasting. It also may be used as superior refractories.
