介绍了安徽李楼铁矿60万吨选矿车间原矿输送泵运行不到500h的磨损情况,分析认为气蚀是造成原矿泵叶轮严重磨损的重要原因,另外泵的叶轮材料、安装位置及矿粒特性等对磨损也有很大影响。最后提出了减轻渣浆泵磨损的建议措施,希望能给李楼铁矿在建的500万吨选厂原矿泵设计选型提供参考。
The paper introduces the abrasion situation when the ore pump of the 600kt beneficiation workshop in Anhui Lilou Iron Mine is operated for less than 500h. It is considered that the cavitation is the important cause of the serious abrasion of the impeller of the ore pump. In addition, the pump impeller material, installation location and ore grain characteristics And so on wear has a great impact. At last, the suggestion of reducing the wear of slurry pump is put forward, hoping to provide references for the design and selection of the ore pump of 5 million tons plant under construction in LiLou iron mine.
