Brown fused alumina/brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials.
The bauxite was fused in the furnace with high temperature 2250℃
The brown fused alumina block was crushed after smelted in the furnace
BLOCK OF BFA
The block of BFA was waiting for further process in the warehouse
Name:Vibrator Sieving Machine
Usually the BFA sand would be sieved by five sieve mesh to make sure the quality strictly accroding with the FEPA/JIS standard .
