用扫描电镜等方法对研磨铝矿对球磨机衬板进行了失效分析。在热强碱腐蚀和冲击磨料磨损的综合作用下 ,高应力磨料磨损是衬板的主要失效机制 ,但未见应力腐蚀开裂现象。
With the method of scanning electron microscope and other methods, the failure analysis of the mill aluminum liner on the mill liner was carried out. Under the combined effect of hot alkali corrosion and impact abrasive wear, high stress abrasive wear is the main failure mechanism of the liner, but no stress corrosion cracking phenomenon is found.
