Brown fused alumina is made from high quality bauxite and anthracite etc.by fusing in a tiltpour
or 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.
It is suitable for manufacturing vitrified and resinoid tools, lapping, polishing and blasting, also
used as superior refractory materials.
