产品特性/Characteristics:
球体圆整度好，表面光滑，有珍珠般光泽。
有极好的韧性，耐冲击，在高速运转中不碎裂；极小的摩擦系数使TZP锆珠对设备的磨损很低。
TZP锆珠的耐磨性是玻璃珠的30-50倍，是硅酸锆珠的5倍左右。
TZP锆珠密度比其它陶瓷磨介高，研磨效率是玻璃珠的6-8倍，是硅酸锆珠的2-3倍，可以提高物料固含量或加大物料流量。
1) Preventing material from contamination because of its extreme low wear rate.
2) High grinding efficiency.
3) Lower total costs due to the long using life.
4)Suitable for high velocity operations and wet grinding operations.
