介绍了冬瓜山铜矿φ8.35 m×3.96 m半自磨机钢球加大到φ180mm,实际混合充填率增加到35%以上,处理量翻一番而达产的实际。提出把半自磨机造成钢球加大到φ240mm、实际混合充填率增加到50%以上的溢流半自磨机,来单独完成破磨生产任务,改造费用150万元,预计增收节支效果明显。
Introduced the Dongguashan Copper Mine φ8.35 m × 3.96 m semiautomatic mill ball to φ180mm, the actual mixing filling rate increased to 35% or more, the amount of treatment to double the actual production. Proposed to increase the semi-autogenous mill ball to φ240mm, the actual mixing filling rate increased to more than 50% of overflow semi-autogenous mill, to complete the crushing production tasks alone, the transformation costs 1.5 million yuan, is expected to increase income and savings effect obvious.
