Analysis of the two weak links in the structure of SXHD-7 super-weight cone crusher

论述了主轴与水封防尘系统是SXHD－7圆锥破碎机构造中的薄弱环节，并以德兴铜矿大山选矿厂多年来使用该种圆锥破碎机时生产实践经验为依据加以论证。

The paper points out that the main shafr and water-sealed dust proof system are the two weak links existed in the structure of SXHD-7 super-weight cone crusher, and discusses and demonstrates based on the practice and experiments in Dashan Concentrate Plant of Dexing Copper Mine.
