连云港花岗岩破碎生产线，花岗岩破碎设备

一、项目概况
在江苏省连云港市灌南县新安镇，一座现代化花岗岩破碎生产线稳定运行，这是世邦集团在该地区打造的精品砂石骨料示范项目。该生产线专业处理当地更好花岗岩原料，生产高标准建筑用砂石骨料，为区域基础设施建设提供了重要原料保障。

二、技术方案

    原料特性处理
    生产线主要处理外购花岗岩原料，其莫氏硬度达6-7级，抗压强度120-250MPa。针对花岗岩的高硬度特性，世邦技术团队特别优化了以下处理方案：

    采用"颚破+圆锥破+立轴破"的三段式破碎工艺
    各环节匹配专用耐磨件，使用寿命提升30%以上
    设置专用除铁装置，降低金属杂质影响

    核心设备配置

工序 设备型号 技术特点 数量
给料 ZSW200×120 变频控制，精准给料 2台
粗碎 PE750×1060 重型设计，强力破碎 1台
中细碎 HPT300 液压调节，层压破碎 1台
制砂 VSI5X1145 石打石原理，成品粒型优 1台
筛分 S5X系列 聚氨酯筛网，分级精确 3台

    工艺流程优化
    原料 → 预筛分除土 → 颚式粗碎 → 圆锥中细碎 → 分级筛分 → 立轴制砂 → 成品筛分 → 储存
    其中特别设计的返料系统确保超粒物料100%回破
