一、项目概况：绿色智能生产线赋能基础建设

在云南红河州泸西县，一条现代化的石灰石破碎制砂生产线巍然矗立，以更好的性能为当地基础设施建设持续输送高品质骨料。该项目由混凝土行业龙头企业投资建设，黎明重工凭借成熟的EPC总包服务能力，为其提供了从规划设计到设备调试的全流程解决方案。生产线自投产以来，以稳定的运行状态、优异的成品质量，成为西南地区砂石骨料生产的标杆示范项目。

项目采用高品质石灰岩为原料，通过科学配比的多级破碎工艺，生产出的机制砂颗粒圆润、级配连续，碎石产品呈规则立方体，针片状含量极低。这些特性更好契合高性能混凝土对骨料的严格要求，为搅拌站提供了可靠的原材料保障。

二、工艺亮点：创新技术成就更好品质

1. 科学布局的破碎系统
生产线核心采用"颚破+反击破+制砂机"三段式破碎工艺。PEW欧版颚式破碎机作为一级破碎设备，其优化的深腔结构和重型偏心轴设计，可好的处理大块石灰石原料；PFW欧版反击破采用三腔型转子，通过多重撞击、研磨作用，显著提升中碎效率；VSI5X立轴冲击式制砂机则通过"石打石"和"石打铁"双重破碎模式，确保成品砂的细度模数和颗粒形状达到最优水平。

2. 智能化控制系统
项目配套建设了更好控制室，实现设备启停联动、运行参数远程监控和故障预警功能。通过在线粒径监测仪对成品料进行实时检测，配合自动化分料系统，确保各规格骨料精准分级。这种智能化生产方式不仅降低了人工成本，更使产品合格率保持在行业实践水平。

3. 绿色环保设计
整条生产线采用全封闭式钢结构厂房，主要扬尘点配备脉冲式除尘系统，粉尘排放浓度远低于国家标准。水循环系统实现洗砂废水零排放，沉碴经压滤处理后可用于矿山复垦。设备基础采用减震设计，配合消音屏障，将噪声影响降至最低，体现了现代砂石生产线与生态环境和谐共生的理念。
