摘　　要：耐磨氧化铝球的建材行业标准JC/T 848.1-2010中采用的球磨罐转速为80r/min,球与球之间相对运动速度不大于0.837m/s。该方法转速低,瓷球所受的摩擦与撞击作用太弱,不适于测定准纳米耐磨氧化铝球或同类高耐磨、高耐冲击性的瓷球。为此笔者采用转速为480r/min、线速度约为4m/s且每旋转一周罐体就发生二次偏心振动的快速磨测定耐磨球的磨耗,采用与无锡建材试验机械厂生产的DYE-600型恒应力压力试验机同类型的压力试验机测定耐磨球的压碎强度,为水泥球磨等有强烈冲击作用的使用场合优选耐磨球提供了有效的测试对比方法。In the industry standard about the wear resistance of alumina ball JC/T 848.1- 2010, the mill speed is 80 r/min, relative velocity between balls is less than 0.837 m/s. The friction and impact is too weak so that it is not suitable for the determination of quasi nanometer alumina grinding ball or similar porcelain ball with high wear resistance, high impact re- sistance. In this paper, determination of abrasion resistance is using quick mill with rotation rate of 480 r/min, where line speed is about 4 m/s and the bailing--tank occurs two eccentric vibration per rotation; crushing strength of grinding ball is tested using machine of the same type with DYE--600 type constant pressure testing machine. This new test method is ef- fective for strong impact applications such as cement milling to optimize wear balls.
