Alumina Grinding Ball are high grade milling media made by advance cool isostatic pressing technology and fired at high temperature.
In order to catch the rapid increasing demand of grinding media and provide full series to customers,we have developed grinding media with92%Al2O3,75%Al2O3 and 65%Al2O3.The technical data of each series is listed as following table.
With overwhelming merits in higher density,more regular shape,easily classifying and assorting,superior grinding efficiencies and competitive price prior to natural cobble stones and conventional grinding media.
