Product Description

Product Description:

Brown corundum is created using high-quality bauxite, anthracite, and iron filings, and is smelted at temperatures of 2000°C or higher. It is then crushed and plasticized using a self-grinding machine, followed by magnetic selection to remove any remaining iron. The resulting material is then sieved into various sizes, with a dense and hard texture, making it ideal for use in ceramics, abrasive resins, grinding and polishing, sandblasting, and precision casting. It also serves as a high-quality refractory material.


What makes brown corundum stand out is its high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and excellent corrosion resistance. It has been extensively used by numerous fireproof production companies, proving its ability to resist explosions, chalking, and cracking during application. Moreover, it is more cost-effective than traditional brown corundum, making it the perfect aggregate and filler for fused alumina refractories.




Brown corundum is well-suited for a variety of industries and can be reused multiple times, with the potential for even more cycles if it retains its cutting ability. Once it has lost its cutting ability, it can still be recycled and used in the construction industry as a cement additive. The high reusable rate of brown corundum can greatly benefit enterprises by reducing costs.

Sandblasting is a widely used industrial process that involves propelling fine particles at high speeds to clean, polish, or etch a surface. It is commonly used in various fields such as environmental protection materials, aluminum profile, copper profile glass, washed jeans, and precision molds.


Filter Media

Filter media is an important component used in the purification of drinking water and wastewater. They are also suitable for non-ferrous metal beneficiation and act as a weighting agent in oil drilling mud.


Hydraulic Cutting

Hydraulic cutting is a versatile process used in a variety of industries, including washing plant, sandblasting, steel structure plant, micro powder plant, grinding wheel plant, sandpaper and gauze plant, and in the crystal and glass industry.
