時間:2025-12-13 14:54 點(diǎn)擊: 次
山西臨汾素有"華夏好的都"的美譽(yù)，不僅是山西省重要的歷史文化名城，更是新型能源和工業(yè)建設(shè)的核心區(qū)域。該地區(qū)礦產(chǎn)資源豐富，其中鐵礦資源尤為突出，總儲量達(dá)4.2億噸，磁鐵礦儲量占比近50%，高品位富礦比例位居全省前列。
在這樣的資源優(yōu)勢背景下，位于臨汾市襄汾縣大鄧鄉(xiāng)的鐵礦石破碎選礦項(xiàng)目應(yīng)運(yùn)而生。該項(xiàng)目自2021年投入運(yùn)營以來，憑借先進(jìn)的工藝技術(shù)和智能化設(shè)備配置，已成為當(dāng)?shù)氐V山資源開發(fā)利用的標(biāo)桿性項(xiàng)目。生產(chǎn)線設(shè)計采用三段一閉路、多段磁選循環(huán)系統(tǒng)等創(chuàng)新工藝，實(shí)現(xiàn)了鐵礦石的好的破碎和精選，同時配套建設(shè)的建材生產(chǎn)線將尾礦資源化利用，開創(chuàng)了礦產(chǎn)品精深加工的新模式。

C6X125顎式破碎機(jī)：采用革命性的可拆裝無焊接結(jié)構(gòu)機(jī)架設(shè)計，維護(hù)便捷性提升40%。優(yōu)化的破碎腔型使其處理硬巖時效率提高25%以上。
HST系列圓錐破：液壓潤滑一體化設(shè)計減少30%的維護(hù)時間。智能控制系統(tǒng)可實(shí)現(xiàn)"一鍵排料口調(diào)整"，大大提升了操作便捷性。
三、生產(chǎn)工藝流程解析
原料處理階段
井下開采的鐵礦石原礦（粒度≤700mm）通過重型板式給料機(jī)均勻輸送到粗碎工序。經(jīng)除土篩分后，原料進(jìn)入C6X顎式破碎機(jī)進(jìn)行初級破碎。
中細(xì)碎環(huán)節(jié)
粗碎后的物料通過皮帶輸送系統(tǒng)進(jìn)入由4臺HST單缸液壓圓錐破組成的中細(xì)碎工段。不同腔型的設(shè)備組合配置，實(shí)現(xiàn)梯級破碎，確保成品粒度均勻。
分級選別系統(tǒng)
破碎后的物料進(jìn)入S5X圓振動篩進(jìn)行分級篩選，形成閉路循環(huán)。
合格的0-10mm物料進(jìn)入多段磁選系統(tǒng)，通過強(qiáng)磁選工藝分離出高品質(zhì)鐵精粉。
尾礦進(jìn)入專門的骨料加工線，生產(chǎn)建筑用砂石骨料。
環(huán)保處理系統(tǒng)
項(xiàng)目配套建設(shè)完善的除塵體系，采用"集塵罩+布袋除塵器"的組合工藝，粉塵捕集率超過98%。同時設(shè)置封閉式儲料棚和噴淋系統(tǒng)，實(shí)現(xiàn)全流程清潔生產(chǎn)。
