磁鐵礦破碎選礦，單缸液壓圓錐破在內(nèi)蒙古包頭某礦業(yè)磁鐵礦破碎選礦技改項(xiàng)目的應(yīng)用。

內(nèi)蒙古包頭礦山破碎選礦生產(chǎn)線升級改造項(xiàng)目報(bào)告

    項(xiàng)目背景與概況
    內(nèi)蒙古包頭磁鐵礦項(xiàng)目是國內(nèi)重要的鋼鐵原料生產(chǎn)基地，年處理原礦能力達(dá)600萬噸。該生產(chǎn)線始建于2018年，原設(shè)計(jì)產(chǎn)能400噸/小時(shí)，采用傳統(tǒng)破碎工藝。但在實(shí)際運(yùn)行中，暴露出以下突出問題：

    設(shè)備性能不穩(wěn)定，故障頻發(fā)
    破碎效率低下，成品合格率不足70%
    能耗指標(biāo)偏高，噸礦電耗超標(biāo)
    維修成本居高不下，嚴(yán)重影響經(jīng)濟(jì)效益

    技術(shù)改造方案及實(shí)施
    經(jīng)深入診斷，技術(shù)人員確定了"設(shè)備升級+工藝優(yōu)化"的雙軌改造方案：

（1）關(guān)鍵設(shè)備升級
① 粗碎系統(tǒng)：

    采用PEW860歐版顎破/C6X系列顎破替換原設(shè)備
    優(yōu)化破碎腔型，采用V型對稱結(jié)構(gòu)
    升級液壓調(diào)整系統(tǒng)，實(shí)現(xiàn)快速排料口調(diào)節(jié)

② 中碎系統(tǒng)：

    選用HST250單缸液壓圓錐破
    配備智能控制系統(tǒng)，實(shí)時(shí)監(jiān)測運(yùn)行參數(shù)
    采用液壓保護(hù)裝置，沖擊保護(hù)響應(yīng)時(shí)間<0.1秒
    優(yōu)化破碎腔型，提高破碎比至4.5:1

③ 細(xì)碎系統(tǒng)：

    配置HPT多缸液壓圓錐破
    采用層壓破碎原理，提升細(xì)碎效率
    配備自動潤滑系統(tǒng)，延長軸承壽命

（2）工藝流程優(yōu)化
建立"三段閉路破碎"新型工藝系統(tǒng)：

    粗碎段：60-300mm入料，開路破碎
    中碎段：閉路循環(huán)，篩上料返回
    細(xì)碎段：閉路破碎，確保<13mm
    配置S5X好的振動篩，篩分效率達(dá)95%

    技術(shù)創(chuàng)新亮點(diǎn)
    （1）圓錐破技術(shù)突破

    采用專利液壓系統(tǒng)，調(diào)節(jié)精度±1mm
    配備智能控制面板，實(shí)現(xiàn)一鍵式操作
    優(yōu)化主軸轉(zhuǎn)速，提高處理能力30%
    改進(jìn)耐磨材料，襯板壽命延長50%

（2）系統(tǒng)集成創(chuàng)新

    研發(fā)專用控制系統(tǒng)，實(shí)現(xiàn)全線聯(lián)動
    建立遠(yuǎn)程監(jiān)控平臺，24小時(shí)實(shí)時(shí)監(jiān)測
    開發(fā)智能預(yù)警系統(tǒng)，故障預(yù)判準(zhǔn)確率85%

    實(shí)施效果評估

【指標(biāo)對比表】
指標(biāo) 改造前 改造后 提升幅度
處理能力 320t/h 420t/h +31%
設(shè)備運(yùn)轉(zhuǎn)率 75% 93% +18%
成品合格率 68% 92% +24%
噸礦電耗 8.7kWh 6.2kWh -29%
    項(xiàng)目意義與推廣
    本項(xiàng)目成功實(shí)施后，已成為內(nèi)蒙古地區(qū)礦山技改的示范工程：
    （1）經(jīng)濟(jì)效益

    年增產(chǎn)值約2.3億元
    投資回收期縮短
