“四省通衢汇龙游”，地处浙江的龙游县，凭借四通八达的水路交通与丰富的河道资源，成为区域基建发展的重要枢纽。近年来，随着当地基础设施建设的加速推进，更好砂石骨料的需求持续攀升。为规范砂石市场、整合河道资源，由政府主导的龙游河卵石制砂项目应运而生。

项目选址紧邻衢江，两处生产现场规模宏大，占据衢江流段核心位置，依托便利的水运条件，直接从河道就地取材，由船只将河卵石原料运送至生产线，大幅降低了物流成本，也减少了对山体开采的依赖，更好契合绿色发展理念。项目自建成起，便成为当地砂石供应的核心力量，源源不断为各类重点工程输送高品质骨料。

 

项目的核心竞争力，离不开黎明重工提供的高性能破碎筛分设备。整条生产线配置两条完全相同的作业线，共配备多台PE600×900深腔颚式破碎机、HST160单缸液压圆锥破碎机以及YZS1860振动筛，构建起一套好的稳定的生产体系。

PE600×900深腔颚式破碎机作为初级破碎的主力，凭借深腔破碎腔型，能一次性处理更大粒径的河卵石，破碎效率远超传统设备。其颚板采用高锰钢材质，耐磨性极强，面对河卵石这类高硬度物料，依然能保持长久稳定的作业状态，有效降低了设备的维护成本。

经过粗碎后的物料，被送入HST160单缸液压圆锥破碎机进行二次整形。这款设备采用先进的层压破碎原理，能将物料破碎成粒型更圆润、级配更合理的成品，不仅满足高铁等重点工程对骨料的严苛要求，还能减少后续制砂环节的耐磨件损耗。单缸液压系统的设计，让设备的排料口调整更便捷，遇堵时能自动清腔，大大提升了生产线的智能化水平与运行稳定性。

YZS1860振动筛则承担着物料分级的关键任务，多层筛网结构能精准筛分出不同粒度的产品，确保成品砂与碎石的规格完全符合工程需求。其耐磨筛网设计，有效延长了设备使用寿命，减少了停机更换部件的频次。

在工艺流程加持下，整套生产线实现了资源的最大化利用与好的产出。原料首先进入振动筛进行预筛分，天然细砂直接送入洗砂机清洗后成为成品河砂，省去了破碎环节，充分利用了自然资源。

预筛分后的大块河卵石进入颚式破碎机进行粗碎，破碎后不符合粒度要求的物料会被送回重新破碎，确保所有进入下一道工序的物料都能达到标准。经过粗碎的物料进入圆锥破碎机进行整形，处理后的物料再次进入振动筛分级，0-5mm的物料进入洗砂机清洗后成为干净的机制砂，10-20mm和20-40mm的物料则直接作为碎石产品输出。

这种“预筛分+两段破碎+洗砂”的流程设计，不仅实现了河卵石资源的全利用，还能同时产出多种规格的成品，从细腻的机制砂到不同粒径的碎石，全面覆盖建筑、道路、桥梁等各类工程的骨料需求。

 

除了好的的生产能力，项目在环保与智能化方面也表现出色。生产线采用全封闭式设计，搭配隔音厂房，有效控制了噪音污染，避免对周边环境造成影响。污水处理系统贯穿整个生产环节，实现了生产用水的循环利用与零排放，真正做到了清洁生产。

在智能化操作方面，生产线配备先进的控制系统，能实现设备的远程监控与参数调整，操作人员只需在中控室就能掌握全线运行状态，不仅降低了人力成本，还能及时发现并排除故障，确保生产线始终处于稳定运行状态。
