江西九江时产800吨硅质岩制砂生产线项目介绍

    项目名称：江西九江湖口县800t/h硅质岩湿法制砂EPC总包项目
    建设单位：湖口县某矿业公司
    矿石类型：建筑石料用硅质岩（SiO₂含量≥85%，含泥量15%~20%）
    成品规格：0-4.75mm精品水洗机制砂（GB/T 14684-2022标准）
    EPC投资：1600万元
    核心工艺：两段破碎+湿法制砂+尾水零排放

核心设备配置——圆锥破碎机的关键作用

本项目针对高硬度硅质岩的特性，采用多缸液压圆锥破碎机作为中碎核心设备，其技术优势与选型要点如下：

    设备选型依据
        岩石特性：硅质岩莫氏硬度7级，抗压强度100~300MPa，传统破碎设备磨损严重。
        产能匹配：时产800吨需求，需确保破碎效率与成品粒型均衡。

    多缸液压圆锥破的工艺优势
        好的破碎：层压破碎原理，显著降低针片状颗粒（成品针片状≤8%）。
        智能调节：液压系统实时调整排料口（8-50mm可调），适配不同筛分需求。
        耐磨设计：高锰钢衬板+迷宫密封结构，硅质岩工况下寿命提升40%。

    工艺流程中的定位

    原料（0-800mm）→ 颚式破碎机（粗碎）→ **多缸圆锥破（中碎）** → VSI6X制砂机（整形）→ 湿式筛分→ 洗砂→ 成品 

        中碎环节：圆锥破将粗碎后的物料（≤200mm）破碎至≤50mm，为制砂机提供理想进料。
        节能表现：相比传统弹簧圆锥破，能耗降低15%，吨电耗≤1.8kW·h。

湿法工艺改造亮点

原干法生产线因硅质岩含泥量高（15%~20%）导致粉尘超标、产能不足，改造后通过以下措施实现达标：

    圆锥破与湿法系统的协同
        预筛分除泥：原料经振动筛预洗，减少进入圆锥破的含泥量，降低设备磨损。
        水循环配合：破碎后的物料直接进入洗砂回收系统，实现砂、泥分离。

    环保成效
        粉尘控制：湿法工艺+除尘设备，现场粉尘浓度＜10mg/m³（国标≤30mg/m³）。
        尾水处理：压滤机干排污泥（含水率＜18%），清水回用率达80%。

EPC总包技术集成
设计中重点优化了圆锥破与其他设备的联动性：
定制化方案：根据硅质岩abrasiveness（磨蚀性）调整圆锥破转速与腔型。
    智能运维：配备远程监控系统，实时监测轴承温度、润滑油压等参数，故障率＜1%。

项目成果：

    产能达标：实际产量稳定在780~820t/h，砂石含泥量＜2%。
    经济收益：精品砂售价较普通砂提升30%，投资回收期＜2年。
