位于湖南衡阳县井头镇的石材废料资源化利用项目，依托当地丰富的石材资源，采用黎明重工全套破碎筛分设备，实现年处理300万吨石材废料的规模化生产。该项目有效解决了当地石材加工废料堆积问题，实现了资源的循环利用。

技术特点

    采用三级破碎系统设计：PE750×1060颚式破碎机负责初级破碎，HPT500多缸液压圆锥破进行中细碎，2台VSI6X1263制砂机完成最终整形制砂
    配套洗砂脱水系统和智能控制系统，保障成品砂质量的稳定性
    生产线设计产能为每小时500吨

环保效益
项目通过将花岗岩等石材废料转化为符合建筑标准要求的机制砂，不仅解决了废料堆积问题，还实现了资源的有效利用。生产过程中采用闭环水处理系统，减少了粉尘排放和污水产生。

设备优势
黎明重工VSI6X制砂机采用多种破碎模式组合，可根据原料特性调整工艺参数，优化成品砂的颗粒级配和细度模数。智能控制系统的应用有助于提升设备运行效率。

项目意义
该项目的成功实施为同类矿产区域的废料处理和资源化利用提供了实践经验，展示了绿色矿山建设的可行路径。
