Description

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**7 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 Typical Chemical Analysis Al2O3 Fe2O3 TiO2 SiO2 CaO *5.*0% 0.*2% 2.*6% 0.*8% 0.*2% Physical Properties Color Dark brown Shape Blocky, tough and sharp Crystal Form Alpha-alumina trigonal system True Specific Gravity 3.*6 g/cm3 Hardness ***0 Knoop scale; 9.0 Mohs scale Melting Temperature About ***0 ℃ Magnetic Material 0.***6% Toughness *0.*6 Hydrophilic *4.*0 Bulk Density Test Value (g/cm3) Grit No F*2 F*4 F*6 F*0 F*2 F*4 F*0 F*6 F*0 F*6 B.D 1.*4 1.*1 1.*0 1.*7 1.*4 1.*4 1.*1 1.*9 1.*5 1.*5 Grit No F*4 F*0 F*0 F*0 F*0 F**0 F**0 F**0 F**0 F**0 B.D 1.*2 1.*2 1.*9 1.*5 1.*1 1.*1 1.*9 1.*7 1.*6 1.*2 Grit Size Available (F) *2 *4 *6 *0 *2 *4 *0 *6 *0 *6 *4 *0 *0 *0 *0 **0 **0 **0 **0 **0 Particle Size Distribution (PSD) PSD According to ISO, ANSI, FEPA and JIS.
