易门铜矿木奔选厂精矿脱水作业,原设计为浓密机、园盘真空过滤机和干燥机组成的三段脱水工艺。投产28年来,由于设备效率低而造成能耗高,备件消耗高和金属流失高的“三高一低”被动局面。根据测定:每天仅从烟囱里流失的金属铜就有36.7公斤,每年干燥机处理3万多吨铜精矿,金属铜流失高达14.175吨,价值7.9335万元;而且严 Yimen Copper Mine Benxi select concentrate dehydration operation, the original design thickener, disk vacuum filter and dryer composed of three sections of dehydration process. Put into operation 28 years ago, due to low efficiency equipment, resulting in high energy consumption, high spare parts consumption and high metal loss “three high and one low” passive situation. According to the test, only 36.7 kilograms of copper metal is lost from the chimney every day, more than 30,000 tons of copper concentrate are processed by the dryer each year, and the loss of copper metal is as high as 14.175 tons, worth 79.335 million yuan;
