金堆城钼业股份有限公司三十亩地选矿厂有4台MQG3600×4000格子球磨机,用于浮选前最后一次破碎。1存在的问题磨机出料端盖衬板原采用12Mn铸钢,在使用中发现存在一些问题。(1)衬板硬度大,由于铸造精度不高,难以整修,安装时与端盖配合不好,易形成间隙,使物料冲刷端盖,造成漏料,降低了端盖寿命。(2)由于存在铸造应力及安装应力,使用过程中
Jinduicheng Molybdenum Co., Ltd. thirty mu of the beneficiation plant has four MQG3600 × 4000 lattice ball mill for the last crushing before the flotation. 1 existing problems Mill discharge cover liner original 12Mn cast steel, found in use, there are some problems. (1) liner hardness, due to the casting accuracy is not high, difficult to repair, installation and the end cover with poor, easy to form a gap, the material scour end caps, resulting in leakage, reducing the end cover life. (2) Due to casting stress and installation stress, the use of the process
