Brown corundum is made from high-quality bauxite, anthracite, and iron filings. It is smelted in an electric arc at a high temperature of more than 2,000 degrees. It is crushed and shaped by an autogenous grinder, magnetically separated to remove iron, and screened into various particle sizes. Its texture is dense and It has high hardness and spherical particles. It is suitable for manufacturing ceramics and resin high-consolidation abrasive tools as well as grinding, polishing, sandblasting, precision casting, etc. It can also be used to manufacture advanced refractory materials.

  • Sandblasting - the abrasive has moderate hardness, high packing density, no free silica, heavy specific gravity, and good toughness. It is an ideal "environmentally friendly" sandblasting material and is widely used in aluminum profiles, copper profiles, glass, and washed denim precision molds. and other fields.
  • Free grinding - grinding grade abrasives, used in free grinding of picture tubes, optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, jade and other fields. It is a high-grade abrasive material commonly used in China.
  • Resin abrasives - the abrasives have suitable color, good hardness, toughness, suitable particle cross-section type and edge retention, and are used in resin abrasives with ideal results.
  • Coated abrasives - Abrasives are raw materials for manufacturers of sandpaper, gauze, etc.
  • Functional filler - mainly used in automobile brake parts, special tires, special construction products, etc., and can be used as wear-resistant materials in the construction of highway pavements, airport runways, docks, parking lots, industrial floors, sports venues, etc.
  • Filter media - a new application field of abrasives. Granular abrasives are used as the bottom media of the filter bed to purify drinking water or waste water. It is a new water filtration material at home and abroad, especially suitable for non-ferrous metal mineral processing: oil drilling mud weighting agent.
  • Hydraulic cutting - uses abrasives as cutting media and relies on high-pressure water jets for basic cutting. It is used in cutting oil (natural gas) pipelines, steel and other components. It is a new, environmentally friendly and safe cutting method.
