Product Description
1.Production introduction
brown fused alumina /BFA contains High TiO2 which makes it an extremely durable,could also be used in Ceramic except normal usage.
brown fused alumina /BFA are the perfect material specifically manufactured to be used for general abrasive applications in bonded abrasive tools, and lapping and polishing processes. While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.
2.brown fused alumina oxide applications
Wet and dry blasting
Grinding, lapping and polishing media
Resin bonded grinding wheels and segments
Resin bonded abrasive products
Wear-resistant and fire-proof products
Catalyst carrier
Friction products
3.Size of brown fused alumina oxide

4.Processing technic
Air crush with the lowest bulk density, the shape of the material sharp
Ball milling with the middle bulk density,the shape of the material between sharp and cube.
Bamark with the highest bulk density,the shape of the material cube and circle.
5.Sieves using in processing
BFA is under the standard of FEPA,GB,JISR,ANSI.
Generally,we use 5 sieves for sieving the material.
And also can customize the sieving method for customers' special request.
