位置：江苏省连云港市连云区板桥街道
用途：建设工程公司配套商砼搅拌站，兼顾零售
原料：外购花岗岩（抗压强度150-300MPa，SiO₂含量65-72%）
产量：250吨/小时
成品规格：
    机制砂（0-5mm）：细度模数2.4-3.0，MB值＜1.0  精品骨料（5-10mm、10-16mm、16-26mm）：针片状含量＜8%，压碎值＜12%

二、花岗岩破碎难点与解决方案

1. 高硬度破碎挑战
花岗岩莫氏硬度6-7级，传统破碎设备磨损严重。本生产线采用：
  PE900×1200深腔颚破：锰钢颚板寿命提升至1800小时（常规1200小时）
    HST/HPT液压圆锥破组合：层压破碎降低30%针片状颗粒

2. 成品级配控制
通过三级筛分（S5X系列振动筛）+VSI5X1145制砂机整形，实现：
    5-26mm骨料连续级配达标率＞95%
    0.075mm石粉含量精准控制在7-10%

3. 能耗优化

    圆锥破液压系统节能设计，吨电耗1.8kW·h（行业平均2.3kW·h）
    双HPT300并联配置，设备利用率达92%

三、核心设备与技术参数
工艺段 设备型号 关键参数 创新设计
粗碎 PE900×1200颚式破碎机 进料≤700mm，排料口调整范围95-165mm 液压楔块排料调节系统（调整时间＜5分钟）
中碎 HST250单缸圆锥破 主轴转速320r/min，功率160kW ASRi智能控制系统（粒度偏差±2mm）
细碎 HPT300多缸圆锥破×2 单机产能130t/h，液压压力20MPa 磨损自动补偿装置（3000小时免维护）
制砂 VSI5X1145立轴冲击破 转子转速45-60m/s，成砂率≥45% 四口深腔转子+周护板模块化设计
筛分 S5X2760-3/S5X2460-3×2等 筛分效率≥90%，噪声＜75dB 聚氨酯筛网（寿命延长3倍）
四、环保与智能化亮点

1. 环保指标

    粉尘排放：12mg/m³（国标50mg/m³）
    水循环系统：回收率＞95%
    噪声控制：全线≤75dB（配备橡胶弹簧减振）

2. 智能化管理

    PLC更好控制：一键启停、故障自诊断
        实时调节给料速度（基于电流负荷）
        预警圆锥破衬板磨损（提前200小时）

五、市场应用

    机制砂：供应C30-C60商砼，用于连云港跨海大桥等工程
    骨料：高铁轨枕骨料（16-26mm）、市政透水砖（5-10mm）
