BFA(AE-20)

Brown Aluminium Oxide Type: AE-20

Brown Aluminium Oxide


Type: AE-20

The grains of this kind of product crashed by ball mill machine, its grain shape is more blocky than rolling machine made grains, but its bulk density is less than AE-17 grains. With the medium loose bulk density, and after water washing, strong magnetism removing, very carefully sieve classifying, this kind of abrasive grain normally can match the various vitrified bond Abrasives Products applications.

Process way: Ball Mill Machine
