一、项目背景
重遵高速扩容项目作为西南地区重要交通枢纽工程，桥隧占比高达71.67%，对高品质砂石骨料的粒形、级配及抗压强度提出严苛要求。项目地处贵州喀斯特地貌区，石灰石资源丰富但成分复杂，亟需好的破碎设备实现资源转化与品质升级。
二、设备配置与技术方案
世邦集团为该项目定制了“GF0942振动给料机+PE600×900颚式破碎机+PF1214反击式破碎机+VSI7611冲击破整形机+S5X2160-4振动筛”的全流程解决方案，综合时产达120吨，可稳定生产0-5mm、5-10mm、10-20mm等多规格成品骨料，满足混凝土浇筑及道路基层施工需求。
GF0942振动给料机：均匀喂料，最大进料粒度≤500mm，有效避免堵塞。
PE600×900颚式破碎机：粗碎核心设备，处理能力80-240吨/小时，抗压强度≤320MPa。
PF1214反击式破碎机：中细碎及粒形优化，成品针片状含量≤10%。
VSI7611冲击破整形机：石打石工艺，制砂效率高，成品砂含泥量≤3%。
S5X2160-4振动筛：4层筛分设计，筛分效率≥85%，确保级配精准。
三、技术创新亮点
地质适配性设计
采用高锰钢+铬合金复合材质锤头，耐腐蚀性较普通碳钢提升3倍，适应喀斯特地貌石灰石高硅含量特性。
配置悬挂式磁选机+永磁滚筒，双重除铁工艺去除杂质，保障骨料纯净度，避免混凝土中铁元素锈蚀风险。
智能运维系统
搭载物联网监控模块，实时采集设备振动值、轴承温度、电流等参数，，提前预警并生成维护方案。
支持远程诊断，专家可异地调取数据并指导维修，故障响应时间缩短至2小时内，较传统模式提升75%。
绿色生产优化
全封闭生产系统+脉冲除尘器，粉尘排放浓度≤30mg/m³，优于国家标准。
湿法制砂工艺结合细砂回收系统，砂料回收率达95%，水资源循环利用率≥80%。
四、应用效果与行业价值
产能与品质：生产线稳定运行超3000小时，成品骨料压碎值≤18%，针片状含量≤8%，完全满足高速公路C60混凝土用砂标准。
经济效益：设备故障率≤0.5%，维护成本降低20%，单位电耗较传统方案节省18%。
行业示范：该方案已推广至西南山区多个基建项目，累计处理石灰石超5000万吨，为复杂地质条件下的资源开发提供标杆案例。
