MZS5518湿式自磨机的技术改造

马钢南山矿业公司东山车间选矿厂针对目前矿石变硬并贫化，造成MZS5518湿式自磨机处理量下降、烧轴瓦事故频繁等问题，联合相关厂家对1#自磨机的衬板进行了改造，并将主轴承由滑动轴瓦改为专门研制的滚动轴承。改造后获得了处理能力提高、衬板使用寿命延长、节电、节油及设备故障率降低等显著效果，每年可多创造至少1 290.1万元的直接经济效益。

Technical Transformation of MZS5518 Wet Autogenous Grinding Mill

In view of the reduced throughput of MZS5518 wet autogenous mill and the frequent accidents such as burned bush due to the harder and more diluted run-of-mine ore, Dongshan Workshop, MaSteel Nanshan Mining Co., in cooperation with the relevant manufacturer, has transformed the lining of its 1# autogenous mill. Specially developed rolling bearing is used as the main bearing to substitute the original sliding bearing bush. As a result, the mill throughput is improved, the lining life prolonged, the electricity and oil preserved and the equipment fault reduced, adding a direct annual economic benefit of at least 12.901 million yuan.
