Brown corundum primary sand 36 mesh

Brown corundum is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by melting at 2000 °C in the arc. It is crushed and shaped by self-grinding machine, magnetically removed and sieved into various particle sizes. Its texture is dense and hard. High, granules form spherical, suitable for the manufacture of ceramic, resin high-density abrasives as well as grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture advanced refractory materials.

The brown corundum abrasive has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. After dozens of refractory production enterprises have verified the practice, the product has the characteristics of no explosion, no powdering and no cracking in the application process. In particular, it is much higher than the cost performance of traditional brown fused alumina, making it the best aggregate and filler for brown corundum refractories.
