Recyclable Brown Fused Aluminum Oxide Sandblasting Abrasive F46 F240 Moderate Hardness
Brown Fused Alumina F36 F80 Abrasive Raw Materials For Vitrified Wheel .Brown Fused Alumina is fused and crystallized under the high temperature of above 2250°C with high quality abrasive bauxite as raw material.It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resin grinding wheel.And BFA could be used for abrasive,sandblasting and precision castingBrown corundum production process:Break up the bauxite →add iron filings ,carbon smelting→cooling→break the brown corundum block→manual sorting→different grades of brown corundum Brown fused alumina for refractory advantages:
1) No burst,no pulverization and crack in the using course of refractory
3) High quality bauxite as raw material4) Very low amount of iron oxide5) High purity6) Low coefficient of pansion
Brown corundum for Abrasive SandblastingPrecision casting advantages:
1) Very low amount of iron oxide, suitable for non-ferrous blasting
operations.
2) Sandblasting in the non-iron process.
3) High speed processing.
4) Not affecting the color of the processing cases.
