摘　　要：本文针对广东某硫铁矿选厂碎磨系统设备型号小、数量多,且设备陈旧落后、维护成本高的问题,进行半自磨工艺流程改造。通过矿石性质研究以及碎磨试验确定半自磨工艺模拟选型基础数据。JKSimMet模拟确定该矿半自磨工艺磨矿设备选型结果为1台Φ8.53 m×4.27 m半自磨机,装机功率为5 400 kW以及1台Φ5.8 m×9.5 m球磨机,装机功率为5 400 kW。对3种不同工况条件的模拟显示,该设备规格可以处理不同硬度和细度的矿石,其产品细度基本达到设计要求。该研究结果为企业设备选型以及矿山未来生产调控提供了技术支撑。Based on the problems of old equipment,small type,large quantities,high maintenance costs,etc,technical transformation of SAG mill process was carried out on the pyrite mine in Guangdong.Simulation basic data was confirmed according to the research on ore properties and experiment results of crushing and grinding.OneФ8.53 m×4.27 m SAG mill(5400 kW)and oneФ5.8 m×9.5 m ball mill(5400 kW)were selected according to JKSimMet simulation.Simulation on three different operation conditions demonstrated that different ore with different hardness and fineness could be treated,and the fineness of grinding products could meet design requirement.This study will provide technical support for the equipment calculation and future production adjustment.
