Brown fused alumina F12#-220#
Price: FOB 799$/MT
1.Specifications
Brown Fused Alumina (BFA) is made from Calcined Bauxite.
It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products.
These grains are also used for shot blasting and as polishing media.
Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory.
It is available in grit sizes as per FEPA for abrasive applications and group grits for refractory applications.
2.Size
Size under FEPA with complete model of
8#,10#,12#,14#,16#,20#,22#,24#,30#,36#,40#,46#,54#,60#,70#,80#,90#,100#, 120#,150#,180#,220#
3.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.
4.Sieves using in processing
HaiXu BFA is under the standard of FEPA,GB,JIS,ANSI.
Generally,we use 5 sieves for sieving the material.
And also can customize the sieving method for customers' special request.
