Description:
Brown fused alumina is made from high quality bauxite by fusing in electric arc furnace at a high temperature of more than 2000℃, processed with conecrusher and Barmac crusher by dressing, magnetic-separation and screeing.
Features:
Brown fused alumina has the high density and hardness, good self sharpening and excellent alumina grinding properties. The grains are in blocky shape.
Application:
Brown fused alumina is suitable for manufacturing vitrified and resinoid tools, lapping, polishing and blasting. It also can be used as superior refractory materials.
