中国铝业山西分公司氧化铝厂原矿浆磨制采用棒磨机+球磨机+旋流器一段开路二段闭路的生产流程,磨机出料方式为溢流型。原料磨规格:棒磨机φ3.2×4.5m.球磨φ4.5×6m;系统设计产能为85 t/h。原料磨工序于2005年9月开始进行了试生产,由于各种原因,原料磨的台时产能最大达到80 t/h,球耗较大,衬板使用周期较短,生产流程中薄弱环节较多,磨机系统故障率较高,单台磨机不能长时间稳定运行。 China Aluminum Shanxi Branch of the original mill mill pulp mill + ball mill + cyclone open section of two closed-circuit production processes, mill discharge mode for the overflow type. Material mill specifications: rod mill φ3.2 × 4.5m. Ball mill φ4.5 × 6m; system design capacity of 85 t / h. The raw material grinding process started trial production in September 2005. Due to various reasons, the maximum output of raw material grinding reaches 80 t / h, the ball consumption is relatively large, the use period of the liner is short, and the weak links in the production process More, mill system failure rate is higher, a single mill can not be a long time stable operation.
