Product Description

Product Description:

Brown corundum is a highly sought-after abrasive that is made using high-quality bauxite as a raw material, combined with anthracite and iron filings. This compound is then subjected to arc smelting at temperatures exceeding 2000°C. After smelting, it is crushed and made pliable by utilizing a self-grinding machine. The iron is removed from the substance using magnetic methods, after which it is sieved into a range of sizes. The resulting compound is dense and hard and is available as high spherical pellets. These pellets are ideal for use in the production of various items such as ceramics, high-resistance abrasive resin, grinding and polishing tools, sandblasting equipment, precision casting and more. Additionally, this versatile abrasive can be used to manufacture high-grade refractories.


Brown corundum abrasive is characterized by high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and corrosion resistance. The practice of dozens of fire-proof production companies has verified that this product has the characteristics of no explosion, no chalking, and no cracking in the application process. These characteristics make the brown corundum abrasive stand out from other abrasives on cost-effectiveness when compared to traditional brown corundum. It's no wonder that it is the best aggregate and filler for fused alumina refractories.



Less dust

Brown corundum is used for sandblasting surface treatment due to its high density, which results in less dust during the sandblasting process. This ensures operator safety and improves visibility. In comparison to slag and quartz sand, brown corundum is less brittle and does not produce small particles that can cause environmental pollution.


High Efficiency

Brown corundum is a fast spray grinding method, as its sharp edges can quickly impact the surface of the object. The acceleration and velocity of particles in the air flow is a function of inertance and particle size. Thus, smaller particles can accelerate more easily and produce a higher impact force on the surface of the object. This results in a very high cleaning rate that is usually twice as fast as other conventional abrasives.


Low Depletion

Using brown corundum leads to less loss of abrasive, as its unique particle size allows for more effective particles to hit the surface of the object.

Sandblasting is used in a variety of fields such as environmental protection materials, aluminum profiles, copper profiles, glass, washed jeans, and precision molds. This technique involves using an abrasive material to clean or roughen a surface through the use of compressed air or water. The choice of abrasive material depends on the application and the desired result.


Grinding is another common method used in industries such as picture tubes, optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, and jade. This process involves using an abrasive wheel or belt to remove material from a workpiece to achieve the desired shape or surface finish.


Resin abrasives are a type of abrasive material that is suitable for a variety of applications due to their color, good hardness, toughness, suitable particle cross-section type, and edge retention. This makes them ideal for use in industries such as jewelry, metalworking, and woodworking for applications that require precision and a high-quality finish.
