| 摘 要： | 针对某金矿MQG3660格子型球磨机球荷组成不合理的问题，提出了相应的优化措施。运用球径半理论公式精确计算球径，并对不同球荷进行磨矿对比试验，最终确定了MQG3660格子型球磨机最佳初装球荷尺寸组成（m（Φ80）∶m（Φ70）∶m（Φ60）∶m（Φ40）=10∶20∶30∶40）及补加球荷尺寸组成（m（Φ80）∶m（Φ70）∶m（Φ60）=30∶30∶40）。工业试验结果表明，磨机球荷特性优化后，磨机处理量提高了3.36 t/h，球耗与电耗分别降低了15.57%和9.85%，实现了通过优化球荷特性达到增产、节能及降耗的目的。

| Abstract: | 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. |
