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