河南許昌石灰石骨料生產線——產業鏈延伸標桿項目
河南許昌石灰石骨料生產線——產業鏈延伸標桿項目
一、項目背景：產業鏈整合的必然選擇
客戶作為河南省頭部混凝土企業（涵蓋商混站、干粉砂漿、礦粉加工等業務），2016年面對混凝土行業產能過剩，決定向上游延伸，投資建設高品質砂石骨料生產線，形成"礦山廢石→骨料→混凝土"一體化產業鏈。
核心訴求：
✔ 降低原材料外購成本
✔ 把控骨料質量（粒形、級配、含粉量）
✔ 提升終端混凝土產品競爭力
二、創新選址：與水泥廠協同降本
原料來源：長期合作水泥廠的石灰石礦山剝離廢石（年均廢石量50萬噸）
選址策略：
緊鄰水泥廠布局（禹州市萇莊鎮），共享三大基礎設施：
✅ 礦山破碎系統 → 直接接駁原料通道
✅ 輸送皮帶廊 → 省去原料轉運設備
✅ 電力電網 → 降低配套電網改造成本
效果：較獨立建廠節省基建投資35%，實現"零原料運輸費"運營
三、生產線配置與工藝亮點
1. 設備選型
環節 設備 核心優勢
中細碎 HPT300多缸液壓圓錐破 液壓清腔，適應高硬度石灰石
制砂整形 VSI1140沖擊式制砂機 成品砂細度模數2.6-3.0，粒形優
篩分 3YKN3070圓振動篩 四層篩網，精準分級4種骨料
2. 工藝創新
"圓錐破+沖擊破"雙級整形：使針片狀含量＜8%（高鐵用混凝土標準≤15%）
石粉循環利用：收集5%石粉用于干粉砂漿原料，實現零廢料
智能聯控：與水泥廠共享DCS系統，實現骨料-水泥生產協同調度
四、項目效益
經濟性
▪ 骨料自供成本較外購降低40元/噸
▪ 2023年骨料外銷利潤率達52%（部分供應中鐵等重點工程）
環保性
▪ 年消納廢石50萬噸，減少礦山固廢堆積
▪ 全封閉生產，粉塵排放＜10mg/m³（國標≤20mg/m³）
五、行業示范價值
該項目的成功實踐為混凝土企業延伸產業鏈提供了模板：
選址模型：依托上游水泥廠/礦山，最大化利用現有基礎設施
設備組合：HPT+VSI方案可復用于花崗巖、鵝卵石等物料加工
循環經濟：廢石→骨料→混凝土→建筑固廢再生，形成完整綠色閉環
