刚果铜矿选矿项目中破碎筛分设备的应用与方案

发布时间:2025-11-07发布者:admin

1. 铜的战略价值与刚果资源优势

铜作为现代工业的"命脉金属",在电力电子(导电性)、建筑建材(耐腐蚀)、新能源(光伏、风电)等领域具有能不替代的作用。刚果(金)铜矿储量达7500万吨,占全球15%,是世界上最重要的铜资源国之一。随着全球能源转型加速,铜的需求量持续攀升(国际铜业协会预测2030年全球需求将增长50%),好的开发铜矿资源对保障全球供应链具有重要意义。
2. 选矿关键环节与设备选型

完整选矿流程:

    破碎筛分(预处理)→磨矿分级→浮选/浸出→电解精炼
    其中破碎筛分环节直接影响后续60%以上的生产成本,是决定铜回收率和经济效益的核心工序。

黎明重工定制化方案:
(1)粗碎系统

    PE1200×1500颚式破碎机处理<1000mm原生矿,破碎比达1:10,设备利用率提升30%
    NK移动破碎站实现矿区灵活转场,运输成本降低40%

(2)中细碎系统

    HPT液压圆锥破采用智能液压系统,同比传统设备:
    ✓ 处理量提升15-20%(时产达800吨)
    ✓ 能耗降低18%(专利层压破碎技术)
    ✓ 衬板寿命延长35%(高铬铸铁材质)

(3)筛分系统

    S5X圆振筛构建闭路循环,-5mm细料占比<10%,大幅减轻球磨机负荷

技术创新赋能可持续发展

黎明重工智能控制系统实现:
✓ 远程监测(DCS系统实时显示设备运行参数)
✓ 预警维护(振动传感器提前2周预测机械故障)
✓ 节能优化(根据矿石硬度自动调节破碎腔型)

同时配备脉冲除尘装置,粉尘排放<20mg/m³。
5. 项目落地建议

针对不同规模选矿厂的更多配置:

    大型矿山(10万吨/年以上):
    颚破+HPT圆锥破(3台并联)+多层圆振筛
    中小矿山:
    移动破碎站+CS圆锥破组合机组

黎明重工提供:
✓ EPC总包服务(含设备安装调试)
✓ 耐磨件终身技术支持
✓ 备件非洲本地仓供应(刚果、赞比亚设服务中心)

随着新能源产业对铜的需求爆发式增长,采用好的破碎筛分技术将直接提升矿山经济效益。黎明重工致力于通过智能化、低能耗的设备解决方案,助力刚果铜矿资源价值最大化开发。
