9 Mohs Barmac Aluminum Oxide Blasting Media Brown Fused Alumina F16 for Anti-skid Roads
1. Product Description of Brown Aluminum Oxide
Brown aluminum oxide is also called as brown fused alumina,it belongs to the corundum group,which
select the high-quality bauxite, coke,iron scrap as main material, then fused and purified in an electric
arc furnace, finally made into different
sizes through the special process.
It has the characteristics of high hardness,high toughness,good-self sharpness,strong cutting force etc.
It has wide applications in industry and called as "the teeth of Industry".

4. Classification of Brown Fused Alumina
1st garde brown fused alumina(95% Al2O3Min),2nd brown fused alumina(85% Al2O3) according to the
alumina content;
Fixed furnace,tilting furnace brown fused alumina according to differnet melting furnace;
Barmac,ball milling,ruller,barmac+ruller brown fused alumina according to different crushing method;
Grit size,section sand,micropowder brown fused alumina according to different size.
5. How to Store Brown Aluminum Oxide?
Store in dry,cool and ventilated warehouse;
Marked clearly,store separately to prevent contamination;
Used out after opening within 30 days.
6. How to judge the quality of brown fused alumina?
Judge the quality by appearance: good quality BFA has regular and uniform shape,in brown or dark-red color;
Judge the content of the magnetic substance by iron absorption stone: good quality BFA has fewer magnetic
substance;
Judge the ash content by clear water: good quality BFA has higher clearliness,fewer ash,when put it into the
clear water, the water is still clear.
Judge its hardness by rubbing and pressing: high quality BFA has higher hardness,it will not be broken when
rubbing and pressing by hands.
