旋回式破碎机动锥衬板螺母拆卸工艺的研究及应用

Research and Application of Cone Liner Nut Removal Process for Gyratory Crushers

针对纳米比亚湖山铀矿使用的旋回式破碎机在动锥翻新工作时采用直接旋松大螺母、切割锁紧大螺母及切割火炬环等工艺拆卸螺母,易造成关键部件损伤,检修难度大、备件成本高等问题,结合设备结构布置,研究及应用了新的切割工艺,即通过采用切割上部衬板的方式,避开了螺纹配合及轴颈等敏感区,大幅降低了检修难度,同时节约了备件成本。

The gyratory crusher used in Namibia's Lake Mountain Uranium Mine used to directly loosen the big nut,cut the locking big nut and cut the torch ring and other processes to remove the nut during the dynamic cone refurbishment work,which is easy to cause damage to the key parts,and it is difficult to overhaul,the cost of spare parts is high.Based on this,combined with the structural arrangement of the equipment,a new cutting process is researched and applied,i.e.,by adopting the way of cutting the upper liner,the sensitive areas such as threaded fits and journals are avoided,which greatly reduces the difficulty of overhauling,and saves the cost of spares at the same time.
