Abstract: 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.

Key words: MZS5518 wet autogenous grinding mill, Lining, Bearing, Technical transformation
