陕西汉中石灰石精品骨料项目位于南郑区新集镇，依托当地丰富的石灰岩资源，规划建设年产300万吨砂石骨料生产线。南郑区非金属矿资源覆盖浅山丘陵区域，为项目提供了稳定的原料保障。
核心技术与设备
生产工艺采用“两段破碎、两段筛分”工艺，通过C6X145颚式破碎机进行粗碎，CI5X系列反击式破碎机实现中细碎，并结合VU300SP塔楼制砂系统，实现时产1000吨的稳定产能。

马来西亚客户300吨/小时双齿辊石灰石移动破碎筛分成套设备投产，该项目采用双齿辊破碎和筛分一体化的工艺方案，石灰石成品料成块率明显提高，进而提高了进烧窑成品料的百分比，减少了石灰石资源的浪费，增加了成品料石灰石的储量，提高整条生产线生产效率。

设备优势
C6X颚式破碎机：等腔型曲线设计，降低设备磨损率，提升破碎效率。
CI5X反击破：智能液压系统支持在线调整破碎参数，适应不同物料特性。
VU300SP塔楼制砂系统：立体集约设计，节省3倍用地量，实现物料垂直运输与好的流转。

项目创新与效益
绿色智造标杆
全封闭生产：采用全封闭式车间、负压除尘系统和智能喷淋装置，粉尘排放浓度低于10mg/m³，达到环保与效率的双赢。
节能降耗：塔楼设计减少物料运输距离，降低能耗；设备选型注重低噪、低耗，实现可持续生产。

位于陕西汉中南郑区新集镇，年处理 300 万吨自有矿山石灰岩，成品为砂石骨料。
南郑区非金属矿资源丰富，尤其适合石灰石破碎加工。
生产工艺
采用“两段破碎、两段筛分” 工艺，设备包括：
C6X145 颚式破碎机（粗碎）
CI5X1520/1524 反击式破碎机（中细碎）
VU300SP 塔楼制砂系统（制砂）
综合时产约 1000 吨。

 

【社会经济效益】
项目投产后，每年可替代天然砂石开采约250万方，相当于减少1000亩山地破坏。其生产的精品骨料已通过西成高铁、宝汉高速等重点工程的质量认证，级配均匀性、颗粒棱角度等指标均优于国家标准。据测算，项目全生命周期将带动运输、服务等上下游产业增值超15亿元。

【结语】
从荒山石料到建设基石，这座绿色矿山的诞生，展现了现代装备技术与可持续发展理念的更好融合。未来，随着更多智能化技术的应用，该项目或将成为改写传统砂石行业面貌的里程碑之作。
