江西吉安砂岩碎石制砂生产线
该项目是江西吉安某矿业公司于2021年4月竞得吉水县醪桥镇建筑用砂岩矿后，于2023年初建成的碎石制砂生产线，采用黎明重工科技的破碎设备，具备自动化、环保化、规模化等特点。
一、项目核心概况
背景与定位：项目位于吉水县醪桥镇，生产线选用黎明重工的破碎设备，旨在打造好的、环保的砂石骨料生产基地。
生产特点：全程电控化、中控操作，实现无人值守；采用全封闭加工车间，开采回采率达 95% 左右，符合绿色矿山建设要求。
二、设备配置与工艺
核心设备：
初破：PE1200×1500 颚式破碎机，处理能力强，适用于大块砂岩的粗碎。
中细碎：HST315 单缸液压圆锥破碎机与 HPT500 多缸液压圆锥破碎机组合，前者适合中碎，后者用于细碎，兼具高产量与粒形优化。
制砂与整形：2 台 VSI6X1263 立轴冲击式制砂机，采用 “石打石” 模式，减少设备磨损，提升机制砂粒形质量。
筛分：圆振动筛，实现不同规格砂石骨料的分级。
工艺优势：设备配置兼顾效率与环保，如HPT圆锥破比传统机型产量35%-60%，且采用层压破碎原理，针片状石子减少；VSI制砂机支持两种破碎模式切换，适应不同硬度物料需求。
三、环保措施
粉尘控制：全封闭加工车间结合高压喷雾装置，抑制无组织扬尘；破碎、筛分工段配备袋式除尘器，确保颗粒物排放浓度≤10mg/m³。
废水处理：洗砂废水经三级沉淀池处理后循环使用，泥饼压滤脱水用于矿区复垦或外售制砖，实现废水零排放。
噪声治理：选用低噪声设备，基础减振并加装消音器；车间封闭设计结合厂区绿化，降低厂界噪声至昼间≤60dB。
固废利用：石粉作为混凝土掺合料，废石回填采坑或破碎再利用，固废综合利用率达 100%。
四、市场影响与成本效益
市场供应：主要销往江西本地及周边地区，缓解区域砂石供需压力。
成本分析：设备选型注重性价比，如黎明重工的HPT圆锥破比传统机型节能 10%-15%，降低长期运营成本。
五、未来规划与行业地位
绿色升级：项目已满足《江西省绿色矿山建设标准》，未来或进一步推进数字化矿山建设，如安装在线监测系统实时监控粉尘、噪声数据。
产业链延伸：部分砂岩项目已拓展至干混砂浆、建筑砂浆领域，为混凝土搅拌站提供配套骨料，提升产品附加值。
行业标杆：作为吉安市重点砂石项目，其自动化、环保化模式有望成为赣中地区绿色矿山建设的示范。
六、黎明重工设备
技术创新：HPT多缸液压圆锥破采用固定主轴结构，效率比传统机型高 5%-15%；VSI6X 制砂机通过叶轮设计优化，制砂效率提升 20%。
适应性强：设备支持模块化配置，可根据原料硬度、产能需求灵活调整，如针对砂岩的高硅含量，采用耐磨材料延长易损件寿命。
服务体系：提供从工艺设计到售后维护的全流程支持，如为客户定制智能柔性生产线，实现更好控制室一键切换生产模式。
总结
该项目通过先进的设备配置与环保工艺，实现了砂岩资源的好的开发与可持续利用。其规模化生产、低能耗运营及绿色矿山实践，不仅满足了区域砂石需求，也为行业提供了可复制的标杆模式。未来，随着数字化与产业链延伸的推进，项目有望进一步提升经济效益与环境效益。
