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 BMK machine made grains. With the medium loose bulk density, and after wind blowing dust collection way, strong magnetism removing, very carefully sieve classifying, this kind of abrasive grain normally can match the various Bonded Abrasive Products applications
