一、项目背景

江苏苏州某建材公司为配合当地基础设施建设，在沛县杨屯镇新建一条时产450吨的石灰石碎石生产线，选用世邦集团全套破碎筛分设备。该生产线主要为自营搅拌站供应更好砂石骨料，同时满足周边建筑市场需求。
二、核心设备选型与工艺流程
1. 粗碎阶段：C6X125颚式破碎机

    处理能力：450-500t/h
    进料粒度：≤750mm
    出料粒度：≤200mm
    特点：采用重型机架和高锰钢颚板，适应高硬度石灰石破碎，使用寿命长。

2. 中碎阶段：PFW1318+CI5X1520反击式破碎机

    组合优势：两级反击破串联，实现好的中碎，减少过粉碎现象。
    出料粒度：≤50mm
    特点：
        液压开盖装置，便于检修；
        高铬板锤，耐磨性强，降低维护成本。

3. 制砂阶段：VSI6X1150冲击式破碎机

    技术亮点：
        四口叶轮设计：破碎效率较传统三口叶轮提升20%；
        深腔型转子：增强物料通过能力，成砂率提高15%；
        耐磨件优化：关键部件寿命延长30%-200%。
    成品砂规格：0-5mm（细度模数可调）；
    应用效果：砂粒形圆润，级配连续，符合搅拌站高标准用砂需求。

4. 筛分系统：多层圆振动筛

    分级精度：精确分离0-5mm、5-10mm、10-20mm三种规格骨料；
    闭路循环：超粒径物料返回破碎，提升资源利用率。

三、生产线优势分析

    成本控制：
        骨料自产自用，综合成本较外购降低25%；
        VSI6X1150冲击破节能设计，吨电耗减少15%。

    品质保障：
        成品骨料针片状含量＜8%，优于国标（≤15%）；
        砂石级配优化，提升混凝土强度和易性。

    智能运维：
        设备配备远程监控系统，实时反馈运行数据；
        自动化润滑装置，减少人工干预。

四、运行效益

    产能：稳定达到450t/h，峰值500t/h；
    经济效益：年节省外购骨料费用超600万元；
    社会效益：支持沛县汉文化景区及交通基建，推动区域发展。

五、项目扩展价值

    技术可复制性：适用于高硬度岩石（如花岗岩、玄武岩）破碎制砂；
    环保贡献：生产线封闭设计，粉尘排放＜20mg/m³，符合绿色矿山标准；
    市场前景：为长三角地区砂石骨料集约化生产提供范本。

结语
该生产线通过“颚破+反击破+冲击破”的好的组合，搭配VSI6X1150冲击破的先进制砂技术，实现了石灰石资源的高值化利用。2023年9月回访显示，设备运行稳定，客户满意度高，未来可进一步推广至类似项目。
