贵州纳晴高速骨料生产,黔西南州石灰石制砂生产线

发布时间:2026-01-22发布者:admin

一、项目背景与战略意义
贵州某集团作为我国桥梁建设领域的领军企业,始终以"逢山开路、遇水架桥"的使命担当,参与国家重大交通工程建设。黔西南纳晴高速项目作为贵州省"十四五"交通规划的重点工程,连接纳雍与晴隆两县,全长约160公里,途经喀斯特地貌核心区,地形险峻、地质条件复杂。项目建成后,将极大改善黔西南地区的交通条件,促进区域经济发展与乡村振兴。
在项目建设中,砂石骨料作为核心基础材料,其质量与供应稳定性直接影响工程进度与质量。贵州某集团凭借丰富的工程经验,与世邦集团、黎明重工等行业实践企业展开深度合作,共同打造了一条好的、环保、智能的石灰石破碎生产线,为项目提供了可靠的骨料保障。
二、项目挑战与解决方案
(一)核心挑战
原料特性复杂:项目所用石灰石硬度高(莫氏硬度4-5)、含泥量较高,对破碎设备的耐磨性能与处理能力提出严苛要求。
环保与能耗约束:项目位于生态敏感区,需满足严格的粉尘排放与噪音控制标准;同时,高产能需求下需优化能耗效率。
工艺适配性要求:高速公路对骨料粒型、级配要求极高,需确保成品骨料针片状含量低、级配连续。
(二)技术方案
针对以上挑战,世邦集团与黎明重工联合提供了定制化解决方案:
设备配置:采用"颚破+反击破+冲击破"三段破碎工艺,搭配振动筛分系统。具体设备包括:GF1245振动给料机、PE750×1060颚式破碎机(黎明重工)、PF1315反击式破碎机(世邦)、VSI5X1145冲击式破碎机(世邦)、S5X2460-3振动筛(世邦)。
工艺设计:通过多级破碎与筛分组合,实现物料的精细化处理。颚破进行粗碎,反击破中碎整形,冲击破制砂并进一步优化粒型,振动筛实现精准分级。
三、项目实施与运行成效
(一)生产线建设与调试
生产线选址于黔西南州,充分考虑原料运输与成品配送的便利性。设备安装过程中,世邦与黎明重工技术团队全程驻场指导,确保设备布局紧凑合理,工艺流程顺畅。经过3个月的调试,生产线于2024年正式投产,实现了200吨/小时的稳定产能,满足了项目高峰期的骨料需求。
(二)运行表现与效益
产品质量:成品骨料粒型优异,针片状含量控制在8%以内,级配符合《公路工程集料试验规程》要求,有效提升了混凝土的抗压强度与耐久性。
环保性能:配备脉冲除尘系统与降噪装置,粉尘排放浓度低于20mg/m³,噪音控制在85分贝以下,达到国家环保标准。
经济效益:通过就地取材与自主生产,降低了骨料运输成本,同时减少了对外购骨料的依赖,保障了供应链安全。
四、技术亮点与创新
(一)设备性能优势
黎明重工PE750×1060颚式破碎机:作为粗碎核心设备,其大进料口设计(750×1060mm)可处理最大粒度630mm的石灰石,破碎比大、产量稳定,且采用高锰钢耐磨件,延长了使用寿命。
世邦PF1315反击式破碎机:中碎阶段采用反击破,通过板锤与反击板的冲击破碎,实现物料的好的破碎与整形,尤其适用于石灰石等中硬度物料。
世邦VSI5X1145冲击式破碎机:在制砂环节,该设备采用"石打石"与"石打铁"双模式,兼具制砂与整形功能,成品砂粒型圆润、级配合理。
世邦S5X2460-3振动筛:三层筛分设计可同时分离出多种规格的骨料,筛分效率高达90%以上,确保产品精度。
(二)智能化与绿色化升级
生产线配备智能控制系统,可实时监测设备运行状态、产量、能耗等参数,并通过数据分析优化生产流程。同时,采用全封闭生产车间与皮带输送机,减少粉尘外溢;废水经沉淀处理后循环利用,实现了水资源的零排放。

贵州某集团与世邦集团、黎明重工的合作,体现了"工程需求牵引技术创新,技术创新支撑工程品质"的良性互动。通过整合各方资源,项目不仅好的解决了复杂地质条件下的骨料供应难题,更树立了砂石骨料生产领域的技术标杆。
