    专为信阳地区高硅含量（SiO₂≥65%）河卵石设计
    抗压强度范围：160-300MPa
    含泥量处理方案：预筛分+高压冲洗系统

    工艺流程：
    原料仓→振动预筛（除土）→颚式粗碎→缓冲料堆→圆锥中碎→立轴制砂→多级筛分→砂石分离→成品储存

二、核心设备技术参数升级版

    颚式破碎机组：

    新型肘板结构，冲击载荷降低40%
    液压调整排料口（范围80-220mm）

    智能圆锥破碎系统：

    VSI6X制砂机升级点：

    双电机驱动（2×315kW）
三、智能控制系统2.0

    更好控制台功能：

    实时监控16项关键参数（含振动、温度、油压等）
    产能自动寻优算法（每小时自动调整3-5次）
    智能预警系统：

    轴承温度预警（＞85℃自动降速）
    产能异常分析（对比历史数据）
    易损件更换提醒（精确到±8小时）

四、环保与节能专项

    除尘系统：

    风量设计：60000m³/h
    排放浓度：≤8mg/m³（优于国标）

    节能措施：

    再生制动系统（节电15-18%）
    热能回收装置（利用设备散热）
    夜间低谷电价生产模式

    信阳某项目（2023年6月投产）：

    客户价值：

    相比传统产线：
        年增效约280万元
        占地面积减少25%
        环保投诉零记录

注：本方案可根据具体场地条件提供非标设计，支持EPC总包模式，提供能评、环评、安评全套技术支持。
