这里是广西百色时产150吨石灰石精品砂塔楼项目现场，原料为外购的石灰石。成品为0-3mm精品砂，该项目是塔楼项目，投产至2023年9月已累计生产50多万吨精品砂，成品主供中铁项目。主要设备为VU150干法制砂系统，该系统采用高度集约的塔楼式全封闭布置，集制砂、粒型优化、级配调整、环保处理于一体。


 

一、项目核心亮点

1. 精品砂塔楼创新模式

• 工艺先进性：采用VU150干法制砂系统，实现"破碎-整形-级配调控-除尘"全流程一体化
• 品质保障：产出0-3mm精品砂（细度模数2.6-2.9，含粉量5-8%），完全匹配高铁/桥梁工程C50+混凝土标准
• 环保效能：PM2.5排放＜8mg/m³（优于国标20mg/m³），噪声控制65dB以下

2. 运营数据表现
▶ 单机时产：150吨（年产能60万吨）
▶ 累计产量：截至2023年9月突破50万吨
▶ 客户反馈：中铁项目方评价"砂粒形貌优于天然河砂，混凝土和易性显著提升"

二、关键设备配置方案

1. 前端破碎系统（石灰石预处理）

 

设备类型	更多型号	适用场景	优势特点
颚式破碎机	C6X160	大块石灰石粗碎（≤1200mm）	液压调整排料口，故障率＜2%
反击式破碎机	CI5X1520	中碎（进料≤800mm）	板锤自转补偿技术，寿命延长40%
圆锥破碎机	HPT300	高硬度石灰石细碎	层压破碎原理，成品针片状＜10%

2. 核心制砂系统

• VU150塔楼主机：
  ♦ 四口叶轮设计（通过量提升25%）
  ♦ 石粉双级控制（旋风+布袋除尘）
  ♦ 智能监测系统（实时显示级配曲线）

3. 配套设备

• S5X3675振动筛（3层分级，处理量400t/h）
• XSD3620洗砂机（轮斗式，含粉量精准调控）

三、广西石灰石加工设备选型要诀

1. 硬度适配原则

• 莫氏硬度3-4级（普通石灰石）→ 优先选择反击破
• 含硅量＞5%（高磨蚀性）→ 务必选用圆锥破

2. 场地制约解决方案

• 狭窄场地：更多"颚破+反击破+VU塔楼"三级紧凑型布局
• 矿山配套：建议采用移动式破碎站（如K3轮式机组）

3. 投资回报测算

 

方案类型	设备投资（万元）	吨成本（元）	投资回收期
传统湿法线	800-1200	18-22	2.5-3年
VU干法塔楼	1500-1800	15-18	1.8-2.2年

四、行业应用延展

1. 石灰石尾矿再利用

• 可将0-10mm石屑（传统产线废料）作为VU系统原料，实现：
  → 资源利用率从70%提升至95%+
  → 每吨增效30-50元

2. 差异化产品策略

• 同步产出：
  ✓ 0-3mm精品砂（高价销往搅拌站）
  ✓ 3-10mm瓜子片（用于沥青混凝土）
  ✓ 10-30mm碎石（路基骨料）
