Tilting Furnace Barmac Crushed Brown Fused Alumina for the Shaped and Unshaped Refractories
1. Brown Fused Alumina Descriptions
Brown Fused Alumina is made of high-quality bauxite, anthracite, and iron filings. It is cooled and smelted at a high temperature by more than 2000 degrees in an electric arc. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, the sieve is divided into various kinds. Its compact texture, high hardness, suitable for the manufacture of ceramics, grinding of high tensile metal and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture advanced refractory materials.
Brown Fused Alumina is a generally used material in manufacturing abrasive products and refractory products. It is not so hard as WA grain. The products made from brown fused alumina are very suitable for tough task like large sandblasting outdoor, rough grinding work, etc. Meanwhile, it is a very moderately cost-efficient material comparing with WA.
2. Brown Fused Alumina Characteristics
a. High hardness
b. High crystallinity
c. Good linear flow performance
d. Weak adherence
e. Durable
f. Direct manufacturer
3. Brown Fused Alumina Applications
Brown fused alumina is widely used as a raw material in many industries:
1. F-grit for bonded abrasives such as resin bonded grinding wheels, vitrified grinding wheels.
2. P-grit for coated abrasives such as sandpaper, sanding belts.
3. Blasting media, metal preparation.
4. Laminates, coatings, lapping, polishing.
5. Anti-slip applications like floor, ceramics, auto brake parts.
4. Brown Fused Alumina Packing
Brown Fused Alumina BFA Packing:
1). 25 kg/bag, in bulk;
2). 25 kg/bag, 40 bags/big bag;
3). 25 kg/ bag, 40 bags/pallet;
