Blasting Media Brown Fused Alumina F16- F220 For Hull Painting
Brown aluminum oxide is also called as brown fused alumina,it selects the high quality bauxite as main material,then fused in arc furnace under high temperature,finally screened into different sizes.Brown aluminum oxide has wide particle size from F12-F220#,it is widely used in many industries,so it is also called as "The teeth of Industry".According to different smelting methods,it is divided into tilting furnace,fixed furnace;According to different cushing methods,it is divided into Barmac BFA,roller crushing BFA,Ball milling BFA,Barmac+ Roller crushing BFA.According to different alumina content,it is divided into first class BFA(95% Al2O3 Min),second class BFA(85% Al2O3Min) etc.It has the characteristics of high hardness,high self-sharpness,which can be recycled for 10-12 times in blasting process,so it is also one economic and high efficient blasting media.
