Product Description

Product Description:

Brown corundum is a type of abrasive that is produced by using high-quality bauxite as its raw material, combined with anthracite and iron filings. The manufacturing process involves arc smelting at a temperature of 2000°C or higher. The resulting material is then crushed and plasticized using a self-grinding machine. It is then magnetically selected to remove any iron, and sieved into various sizes. The texture of the resulting product is dense and hard, and is suitable for a variety of applications.


One of the main applications of brown corundum is in the production of ceramic, high-resistance abrasive resin, grinding, polishing, sandblasting, precision casting and high-grade refractories. This is made possible due to the high quality and unique properties of brown corundum. It has a high level of purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance.


The use of brown corundum has been verified by dozens of fire-proof production companies, who have found that the product has the added benefits of being explosion-free, chalk-free and crack-free during application. Its cost-effectiveness is much higher than traditional brown corundum, which makes it the best aggregate and filler for fused alumina refractories. This makes brown corundum a highly valuable and widely used abrasive, due to its exceptional properties and versatility.



One of the unique advantages of using brown corundum for sandblasting surface treatment is that it produces less dust during the process. Compared with slag and quartz sand, which are both easy to break into small particles, brown corundum's relatively high density means fewer particles are suspended in the air, leading to less environmental pollution and improved operator health and safety.


Brown corundum is also extremely efficient as an abrasive material, producing a high cleaning rate and providing fast spray grinding. Due to the small size of its particles, it is also able to penetrate deep into pits and other surface imperfections, resulting in a high-quality finish.

Furthermore, brown corundum is known for its low depletion rate, meaning it is able to maintain its cutting ability for longer periods of time, resulting in less waste and greater cost-effectiveness.


In terms of environmental impact, brown corundum is a pure, non-toxic mineral that does not contain harmful free silicon compounds or other toxic heavy metals. Additionally, the recyclability of brown corundum means that it can be reused multiple times, and even after it has lost its cutting ability, it can still be recycled for use in the construction industry as a cement additive.
