德兴铜矿是我国重点建设的大型有色金属露天矿山。从矿石的开采、运输到破碎、磨矿、浮选、脱水等一系列工序均采用大型机械化设备,耗电量大,生产上年耗电量3亿度左右,是江西省的耗电大户。为了减少生产环节中电能消耗,我们抓住碎矿、磨矿、浮选三个耗电大的关键环节,在改造工艺,革新设备上下功夫。为实现“多碎少磨”先进工艺,投资96.6万美元,引进3台超重型圆锥破碎机,改造原国产破碎机,并增加自动控制系统,使碎矿粒度由20mm降到-15mm,磨
Dexing Copper Mine is a key non-ferrous metal open pit mine under construction in China. From ore mining, transportation to crushing, grinding, flotation, dehydration and a series of processes using large-scale mechanized equipment, power consumption, power consumption last year, 300000000 degrees, is the big power consumption in Jiangxi Province. In order to reduce the power consumption in the production process, we seize the three key steps of power consumption, such as crushing, grinding and flotation, and make great efforts to transform the technology and innovate the equipment. In order to realize the advanced process of “more crushing and less grinding”, the company invested USD 966,000 and introduced 3 super-heavy cone crushers to transform the original domestic crusher and increase the automatic control system to reduce the ore size from 20mm to -15mm.
