信阳河卵石制砂机，时产200吨河卵石破碎制砂生产线

河卵石破碎制砂生产线技术方案（全流程版）

一、产线概述

适应物料：河卵石（莫氏硬度7+）、花岗岩等中高硬度石料
核心工段：粗碎→中碎→细碎→制砂→筛分→洗砂（可选）
标准产能：50-500吨/小时（模块化设计，支持定制）
成品规格：
- 0-3/5mm（精品机制砂，级配可调）
- 5-10mm、10-20mm（骨料，用于混凝土/沥青）

二、设备配置方案

工段	设备选型	关键参数	作用说明
初级破碎	PE颚式破碎机（PE600×900/PE750×1060）	进料≤630mm，处理量80-320t/h	大块河卵石初破，降低后续负荷
二级中碎	HPT多缸液压圆锥破（HPT200/300）	进料≤241mm，产量100-500t/h	层压破碎，减少针片状含量
制砂整形	VSI6X立轴冲击破（VSI6X8528/1150）	进料≤55mm，成砂率≥60%	立方体整形+好的制砂
筛分系统	3YK/4YK圆振动筛（多层筛网）	分级精度±0.5mm	实现砂、石精准分离
洗砂除粉	XSD轮斗洗砂机+细砂回收机	洗净度≥95%	控制含粉量（可选干法生产）
智能控制	PLC更好控制系统	实时监测产量、电流、温度	故障预警+远程调控

三、工艺流程

粗碎阶段：
- 河卵石经给料机均匀送入颚破，破碎至≤200mm
- （针对高含泥量原料可选配预筛分）
中细碎阶段：
- 圆锥破实现闭路循环（未达标石料返回二次破碎）
制砂筛分：
- VSI6X制砂机破碎+整形→圆振筛分级→合格砂进入成品仓
环保处理：
- 干法工艺：脉冲除尘+雾炮抑尘（粉尘≤10mg/m³）
- 湿法工艺：洗砂机+沉淀池（水资源循环利用）

四、技术优势

✔ 高成砂率

VSI6X制砂机“石打石”+“石打铁”双模式，成砂率比传统设备提高20%

✔ 耐磨设计

圆锥破采用锰钢衬板（寿命≥8000h），制砂机抛料头可360°调换使用

✔ 灵活扩展

支持模块化增减设备（如增配移动破碎站、砂石同出系统）

✔ 低能耗

吨砂电耗≤1.8kWh（相比棒磨机节电50%+）

五、案例参考（信阳200t/h项目）

原料：河卵石+花岗岩混合料（抗压强度≥150MPa）
实际运行：
- 成品砂细度模数2.7-3.0，含泥量≤1.5%
- 应用于商混站，替代天然砂成本降低30%

注：可提供EPC交钥匙服务，含场地规划、设备安装调试及人员培训。
