摘要
碎磨系统是选矿工艺的重要组成部分,投资金额占全厂的60%左右,其中半自磨机钢耗、电耗占整个磨矿作业的50%左右,为了节约磨矿成本、降低能耗,企业开展了半自磨机区间加球技术的研究。结果发现,与传统的加球技术相比,区间加球技术可以实现按需加球,提高半自磨机的磨矿细度,钢球单耗降低约24.62%,电耗降低约2.75%,显著增加了企业的经济效益。
Crushing and grinding system is an important part of mineral processing technology,the investment amount accounts for about 60%of the whole plant,in which the steel consumption and power consumption of semi-autogenous mill accounts for about 50%of the whole grinding operation,in order to save grinding cost and reduce energy consumption,the enterprise has carried out the research of ball feeding technology in semi-autogenous mill interval.The results show that,compared with the traditional ball adding technology,the interval ball adding technology can realize the ball adding according to the demand,improve the grinding fineness of the semi-autogenous mill,reduce the unit consumption of steel ball by about 24.62%,reduce the power consumption by about 2.75%,and significantly increase the economic benefits of enterprises.
