导读：

清晨的西江薄雾笼罩，一艘艘满载鹅卵石的货船缓缓驶向云浮郁南。在这里，坚硬的河卵石和花岗岩经过一系列精密加工，蜕变成建筑市场青睐的高品质机制砂。这条由黎明重工提供核心装备的生产线，凭借智能化、节能环保的设计理念，成为大湾区绿色建材产业链上的重要一环。

一、化“顽石”为建材，智能破碎显身手

站在生产线旁，耳边传来的是沉稳而有节奏的机械运转声。直径近1米的原始河卵石被喂入PE900×1200颚式破碎机，经过强大的挤压破碎后，变成拳头大小的碎块。随后，这些原料进入两台HPT500多缸液压圆锥破，通过层压破碎原理，物料被进一步细化。

“相比传统破碎方式，HPT系列圆锥破不仅能降低能耗，还能减少过粉碎现象，让成品砂的颗粒更均匀。”现场工程师介绍道。在制砂环节，三台VSI6X1263立轴冲击破高速运转，通过“石打石”和“石打铁”双重破碎方式，使成品砂的粒形接近于天然河砂，真正实现“粗料精做”。

二、分级+回收，精品机制砂是如何炼成的？

走出破碎工段，进入筛分环节。这里，多台S5X系列圆振动筛正对物料进行精细分级，确保每一寸砂子符合5mm以下的规格要求。与传统筛分设备相比，这些振动筛采用先进的模块化结构，不仅提高了筛分效率，还大大降低了维护成本。

而在水洗区，细沙回收机正好的运转，将传统工艺中流失的细颗粒重新收集利用。“我们这套系统实现了水资源的循环使用，既环保又能提升成品率。”项目负责人表示，“最终产出的机制砂无论是级配、坚固性还是含粉量，都优于国家标准，甚至在部分重点工程中替代了天然砂。”

三、绿色智造，赋能大湾区建设

郁南县位于西江航运要道，凭借便利的水运条件，这里的机制砂产品源源不断地运往大湾区各大建筑工地。云浮市近年来大力发展绿色建材产业，而这条生产线正是行业升级的一个缩影。

“从原料进场到成品装船，全程封闭运行，加上好的的除尘和降噪措施，我们几乎看不到传统砂石厂的粉尘和噪音问题。”现场工作人员介绍道，“黎明重工的这套设备不仅稳定可靠，还能通过远程监控系统实现智能运维，生产效率提升了不少。”
结语：科技助力，让资源利用更好的

在这片粤港澳大湾区的建材生产基地，我们看到的不仅是一套破碎筛分设备，更是一种资源好的利用的现代工业解决方案。从坚硬的河卵石到精细的机制砂，从传统粗放生产到智能环保制造，技术的进步正推动着建筑行业向绿色、可持续方向发展。

黎明重工，作为国内矿山装备领域的代表企业之一，凭借扎实的技术积累和持续的创新能力，正帮助越来越多像云浮这样的地区实现高质量建材生产。未来，随着智能化和绿色矿山的进一步发展，我们相信，会有更多“点石成金”的故事在这片土地上上演。
