硅質巖碎石生產線，
江西九江時產800噸硅質巖制砂生產線項目介紹
項目名稱：江西九江湖口縣800t/h硅質巖濕法制砂EPC總包項目
建設單位：湖口縣某礦業(yè)公司
礦石類型：建筑石料用硅質巖（SiO?含量≥85%，含泥量15%~20%）
成品規(guī)格：0-4.75mm精品水洗機制砂（GB/T 14684-2022標準）
EPC投資：1600萬元
核心工藝：兩段破碎+濕法制砂+尾水零排放
核心設備配置——圓錐破碎機的關鍵作用
本項目針對高硬度硅質巖的特性，采用多缸液壓圓錐破碎機作為中碎核心設備，其技術優(yōu)勢與選型要點如下：
設備選型依據
巖石特性：硅質巖莫氏硬度7級，抗壓強度100~300MPa，傳統(tǒng)破碎設備磨損嚴重。
產能匹配：時產800噸需求，需確保破碎效率與成品粒型均衡。
多缸液壓圓錐破的工藝優(yōu)勢
好的破碎：層壓破碎原理，顯著降低針片狀顆粒（成品針片狀≤8%）。
智能調節(jié)：液壓系統(tǒng)實時調整排料口（8-50mm可調），適配不同篩分需求。
耐磨設計：高錳鋼襯板+迷宮密封結構，硅質巖工況下壽命提升40%。
工藝流程中的定位
原料（0-800mm）→ 顎式破碎機（粗碎）→ **多缸圓錐破（中碎）** → VSI6X制砂機（整形）→ 濕式篩分→ 洗砂→ 成品
中碎環(huán)節(jié)：圓錐破將粗碎后的物料（≤200mm）破碎至≤50mm，為制砂機提供理想進料。
節(jié)能表現：相比傳統(tǒng)彈簧圓錐破，能耗降低15%，噸電耗≤1.8kW·h。
濕法工藝改造亮點
原干法生產線因硅質巖含泥量高（15%~20%）導致粉塵超標、產能不足，改造后通過以下措施實現達標：
圓錐破與濕法系統(tǒng)的協(xié)同
預篩分除泥：原料經振動篩預洗，減少進入圓錐破的含泥量，降低設備磨損。
水循環(huán)配合：破碎后的物料直接進入洗砂回收系統(tǒng)，實現砂、泥分離。
環(huán)保成效
粉塵控制：濕法工藝+除塵設備，現場粉塵濃度＜10mg/m³（國標≤30mg/m³）。
尾水處理：壓濾機干排污泥（含水率＜18%），清水回用率達80%。
EPC總包技術集成
設計中重點優(yōu)化了圓錐破與其他設備的聯(lián)動性：
定制化方案：根據硅質巖abrasiveness（磨蝕性）調整圓錐破轉速與腔型。
智能運維：配備遠程監(jiān)控系統(tǒng)，實時監(jiān)測軸承溫度、潤滑油壓等參數，故障率＜1%。
項目成果：
產能達標：實際產量穩(wěn)定在780~820t/h，砂石含泥量＜2%。
經濟收益：精品砂售價較普通砂提升30%，投資回收期＜2年。
