硅質(zhì)巖碎石生產(chǎn)線，
江西九江時(shí)產(chǎn)800噸硅質(zhì)巖制砂生產(chǎn)線項(xiàng)目介紹
項(xiàng)目名稱：江西九江湖口縣800t/h硅質(zhì)巖濕法制砂EPC總包項(xiàng)目
建設(shè)單位：湖口縣某礦業(yè)公司
礦石類型：建筑石料用硅質(zhì)巖（SiO?含量≥85%，含泥量15%~20%）
成品規(guī)格：0-4.75mm精品水洗機(jī)制砂（GB/T 14684-2022標(biāo)準(zhǔn)）
EPC投資：1600萬(wàn)元
核心工藝：兩段破碎+濕法制砂+尾水零排放
核心設(shè)備配置——圓錐破碎機(jī)的關(guān)鍵作用
本項(xiàng)目針對(duì)高硬度硅質(zhì)巖的特性，采用多缸液壓圓錐破碎機(jī)作為中碎核心設(shè)備，其技術(shù)優(yōu)勢(shì)與選型要點(diǎn)如下：
設(shè)備選型依據(jù)
巖石特性：硅質(zhì)巖莫氏硬度7級(jí)，抗壓強(qiáng)度100~300MPa，傳統(tǒng)破碎設(shè)備磨損嚴(yán)重。
產(chǎn)能匹配：時(shí)產(chǎn)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(shì)
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(diào)節(jié)：液壓系統(tǒng)實(shí)時(shí)調(diào)整排料口（8-50mm可調(diào)），適配不同篩分需求。
耐磨設(shè)計(jì)：高錳鋼襯板+迷宮密封結(jié)構(gòu)，硅質(zhì)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(jī)（粗碎）→ **多缸圓錐破（中碎）** → VSI6X制砂機(jī)（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(jī)提供理想進(jìn)料。
節(jié)能表現(xiàn)：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(diǎn)
原干法生產(chǎn)線因硅質(zhì)巖含泥量高（15%~20%）導(dǎo)致粉塵超標(biāo)、產(chǎn)能不足，改造后通過(guò)以下措施實(shí)現(xiàn)達(dá)標(biāo)：
圓錐破與濕法系統(tǒng)的協(xié)同
預(yù)篩分除泥：原料經(jīng)振動(dòng)篩預(yù)洗，減少進(jìn)入圓錐破的含泥量，降低設(shè)備磨損。
水循環(huán)配合：破碎后的物料直接進(jìn)入洗砂回收系統(tǒng)，實(shí)現(xiàn)砂、泥分離。
環(huán)保成效
粉塵控制：濕法工藝+除塵設(shè)備，現(xiàn)場(chǎng)粉塵濃度＜10mg/m³（國(guó)標(biāo)≤30mg/m³）。
尾水處理：壓濾機(jī)干排污泥（含水率＜18%），清水回用率達(dá)80%。
EPC總包技術(shù)集成
設(shè)計(jì)中重點(diǎn)優(yōu)化了圓錐破與其他設(shè)備的聯(lián)動(dòng)性：
定制化方案：根據(jù)硅質(zhì)巖abrasiveness（磨蝕性）調(diào)整圓錐破轉(zhuǎn)速與腔型。
智能運(yùn)維：配備遠(yuǎn)程監(jiān)控系統(tǒng)，實(shí)時(shí)監(jiān)測(cè)軸承溫度、潤(rùn)滑油壓等參數(shù)，故障率＜1%。
項(xiàng)目成果：
產(chǎn)能達(dá)標(biāo)：實(shí)際產(chǎn)量穩(wěn)定在780~820t/h，砂石含泥量＜2%。
經(jīng)濟(jì)收益：精品砂售價(jià)較普通砂提升30%，投資回收期＜2年。
