井下颚式破碎机基础频繁失效研究与改进

Research and improvement of frequent failure jaw crusher foundation

分析了颚式破碎机基础部频繁失效的原因和危害,提出了改进破碎机基础部的方法。增加中间钢底座和栽筋是解决破碎机基础频繁开裂、延长地脚螺栓使用寿命和高效破矿的关键。改进后取得良好效果。

The base frequent failure reason and harm of jaw crusher were analyzed, and the improvement method of crusher foundation was put forward. Increasing the intermediate steel base is the key to reduce crusher foundation cracking, prolong the service life of anchor bolt and the efficient crushing. The improvement obtained good effect.
