Alulmina Grinding Ball

详情

DeenPu Grinding Balls 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 *2 3.*5 ＜0.*1 9 0.**1 *5 3.*8 ＜0.**5 9 0.***4 Medium Alumina Grinding Balls ****5 2.*3 ＜0.*1 8 ＜0.*1 Carbonized Alumina Grinding Balls ****0 2.**2.9 ＜0.*5 8 ＜0.*8 Appearance Demand High Alumina Grinding Balls Medium Alumina Grinding Balls Carbonized Alumina Grinding Balls Color White White Ash-black Crack Not Permission Not Permission Not Permission Impurity Not Permission Not Permission Not Permission Foam hole Above ф1mm not permission, size in ф0.5mm permit 3 balls Flaw Max. size in ф0.3mm permit 3 balls 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 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.
