Product Description

Product Description:

Brown Corundum is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard. High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.


Brown Fused Alumina is produced by fusion of bauxite in an electric arc furnace at high temperatures. The brownish coloured product shows high hardness as well as extreme toughness. It is produced by fusion of bauxite in a tilting electric arc furnace at high temperatures. The product shows high temperature resistance, strong erosion resistance, high machinery strength as well as thermal stability. It is a good raw material for manufacturing of shaped refractories.




Brown corundum is an effective abrasive material for sandblasting, which is less dust compared to slag. Since it has high density, it can improve the operator visibility and health safety. Brown corundum has high efficiency due to its unique particle size. Moreover, it generates low depletion and a high quality surface treatment. The environment is also cared for since it is a pure, non-toxic mineral. In addition, brown corundum is recyclable and can be reused multiple times.


In terms of the low depletion aspect, its unique particle size ensures that more impact force is directed onto the surface, and thus reducing the abrasive loss. As its cutting edge remains effectively, the treated metal surface has a good standard grade quality, and it prevents embeddings remaining after sandblasting.
