Due to the unreasonable ball diameter and proportion of the MQG3660 grid-type ball mill in a gold mine，some of improved measures were conducted in this study.The ball diameter was calculated based on ball diameter semi-theory formula，and the grinding comparative experiments on different ball charge characteristics were accomplished. Finally，the best initial installation ball diameter and proportion（m（Φ80）∶m（Φ70）∶m（Φ60）∶m（Φ40）=10∶20∶30∶40） and adding ball diameter and proportion（m（Φ80）∶m（Φ70）∶m（Φ60）∶m（Φ40）=10∶20∶30∶40） were achieved.The results of industrial test showed that the capacity of grinding increased by 3.36 t·h-1，and metal consumption and power consumption reduced by 15.57% and 9.85%，respectively.Obviously，the goal of increase production，energy saving and low metal waste was achieved by optimizing the ball charge characteristics in the present work.
