Alumina Grinding BallDEENPU alumina grinding balls are widely used in industries of ceramics, glass, porcelain enamel, pigment, chemicals, etc. They are suitable for applications for ball mill, sand mill, pot mill librating mill and other fine breaking plants with high hardness, high density and anticorrosion.Typical CharacteristicsProductAl2O3(%)Bulk density(g/cm3)Water absorption(%)Moh’s Hardness(scale)Abrasion loss(%)High Alumina Grinding Balls923.650.0190.011953.680.00590.0084Medium Alumina Grinding Balls65-752.930.0180.01Carbonized Alumina Grinding Balls60-702.8-2.90.0580.08 Appearance DemandHigh Alumina Grinding BallsMedium Alumina Grinding BallsCarbonized Alumina Grinding BallsColorWhiteWhiteAsh-blackCrackNot PermissionNot PermissionNot PermissionImpurityNot PermissionNot PermissionNot PermissionFoam holeAbove 1mm not permission, size in 0.5mm permit 3 ballsFlawMax. size in 0.3mm permit 3 ballsAdvantageHigh wear-resistance: The alumina balls’ wear-resistance is higher than the common alumina balls’. When it is working, the ball won’t pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.High density High density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
