如何让“废物”重新变成“资源”？2017年，一条以花岗岩固废为原料的碎石制砂生产线在天岗镇正式投产运行，为当地探索出一条绿色、好的的循环经济发展路径。
天岗镇的石材加工产业历史悠久，规模庞大。在板材切割、打磨等工序中，能不避免地会产生大量边角料和尾料。过去，这些物料多以堆积或填埋方式处理，既浪费了宝贵的矿产资源，也增加了企业环保负担。

成立于1987年的黎明重工，是中国破磨装备制造业的领军企业，隶属于世邦工业科技集团。三十多年来，企业专注于矿山破碎、工业制粉、绿色建材等领域的大型装备研发制造，产品涵盖建筑破碎、矿山破碎、工业制粉、绿色建材四大领域三十多个品种。

如今，黎明重工拥有超过一百二十万平方米的装备制造基地，产品出口全球一百八十多个国家和地区，出口额连续多年稳居行业前列。从青藏高原到非洲大陆，从俄罗斯的寒原到东南亚的热带雨林，黎明重工的设备正在为全球基础设施建设和资源综合利用贡献力量。
一条生产线，解决一个区域的环保难题

2017年，一条以花岗岩固废为原料的碎石制砂生产线在天岗镇正式投产。这条生产线从设计之初就秉持“节能、环保、集约”的理念，采用阶梯式分段破碎设计，上下落差超过十二米。这种布局方式巧妙地利用重力，使物料在破碎过程中自然下落，从而省去了传统生产线中常见的中转料仓，既减少了占地面积，又降低了能耗和粉尘逸散风险。

在经济方面，该生产线以稳定的时产数百吨的产能，有效满足了企业混凝土生产对骨料和机制砂的需求。相比外购原材料，利用本地固废进行生产，不仅降低了原料采购和运输成本，还创造了新的经济价值。产出的成品砂石骨料除了自用外，还服务于吉林市及周边的城际交通工程、地方搅拌站和水稳站，为区域基础设施建设提供了可靠的建材保障。

在行业示范方面，这一项目为国内其他石材产区提供了可复制的固废利用模式。近年来，随着绿色矿山建设标准逐步落地，越来越多企业开始关注尾矿、废石的资源化利用。天岗镇的这条生产线，成为花岗岩产区循环经济的一个鲜活案例。
项目负责人这样说

“生产线投入使用以来，切实解决了我们当地花岗岩板材加工后的尾料、边角料堆积乱放问题。不仅合理分配了工业面积，还减少了重复工作，大大提高了产量和效益。今后我们将继续与黎明重工深化合作。”项目负责人如是评价。
结语：绿色发展，路在脚下

从天岗镇出发，回望过去几年，我国建材行业的绿色转型步伐不断加快。工业固废不再是令人头疼的“包袱”，而是可以重新进入生产链条的宝贵资源。一条好的、环保的破碎制砂生产线，不仅是一家企业的技术升级，更是一个地区产业生态的优化。
