Detailed Description

Alumina Grinding Balls Application: Different from ordinary ceramic balls, alumina grinding balls have a higher mechanical strength. They are suitable for grinding medium used in ball grinding machines. Typical Characteristics Product Al2O3（%） Bulk density（g/cm3） Water absorption（%） Moh’s Hardness（scale） Abrasion loss（%） High Alumina Grinding Balls 92 3.65 ＜0.01 9 0.011 95 3.68 ＜0.005 9 0.0084 Medium Alumina Grinding Balls 65-75 2.93 ＜0.01 8 ＜0.01 Carbonized Alumina Grinding Balls 60-70 2.8-2.9 ＜0.05 8 ＜0.08 Appearance High Alumina Grinding Balls Medium Alumina Grinding Balls Carbonized Alumina Grinding Balls Color White White Ash-black Crack No cracking No cracking No cracking Impurity Without Without Without Bubble > ф1mm not allowed, < ф0.5mm, 3 % allowed Flaw Max. size in ф0.3mm, 3% allowed Advantage 　　 High 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 densityThe high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency. Packaging: Woven bags bags, 25kg/bag, and palletized, or iron drums, 200L/drum and palletized
