在河北承德這片礦產(chǎn)資源富饒的土地上，一座年產(chǎn)300萬(wàn)噸的鐵礦石破碎生產(chǎn)線正詮釋著"中國(guó)制造"的硬核實(shí)力。作為黎明重工在華北地區(qū)打造的又一標(biāo)桿工程，該項(xiàng)目不僅攻克了超貧釩鈦磁鐵礦破碎利用的技術(shù)難關(guān)，更以智能化、綠色化的創(chuàng)新實(shí)踐，為礦業(yè)高質(zhì)量發(fā)展樹立了新范本。
一、破局資源難題的創(chuàng)新方案
灤平縣超貧釩鈦磁鐵礦的開發(fā)利用，長(zhǎng)期面臨"礦石硬度大、選礦能耗高、環(huán)保要求嚴(yán)"三重挑戰(zhàn)。基于三十余年礦山裝備研發(fā)經(jīng)驗(yàn)，黎明重工技術(shù)團(tuán)隊(duì)深入現(xiàn)場(chǎng)調(diào)研后，創(chuàng)造性地提出"梯級(jí)破碎+智能調(diào)控"的系統(tǒng)解決方案。
項(xiàng)目的核心工藝采用"粗碎-中碎-細(xì)碎"三級(jí)破碎流程：
粗碎段配置PE1200×1500顎式破碎機(jī)，其強(qiáng)化型機(jī)架結(jié)構(gòu)和優(yōu)化運(yùn)動(dòng)參數(shù)，可輕松應(yīng)對(duì)700mm以下的超大礦塊；
中碎段采用CSB400彈簧圓錐破，特有的G型破碎腔設(shè)計(jì)實(shí)現(xiàn)高破碎比與低功耗的平衡；
細(xì)碎段部署兩臺(tái)CSD400彈簧圓錐破構(gòu)成閉環(huán)系統(tǒng)，液壓清腔功能確保設(shè)備在連續(xù)作業(yè)下的穩(wěn)定性。
與傳統(tǒng)生產(chǎn)線相比，該方案具有三大突破：通過(guò)層壓破碎原理提升成品立方體含量；采用變頻控制系統(tǒng)精準(zhǔn)調(diào)節(jié)排料粒度；配置脈沖除塵模塊實(shí)現(xiàn)無(wú)塵化生產(chǎn)。項(xiàng)目負(fù)責(zé)人表示："從好的車礦石入料開始，生產(chǎn)線就表現(xiàn)出驚人的適應(yīng)性，達(dá)到了的設(shè)計(jì)目標(biāo)。"
二、硬核裝備背后的技術(shù)底蘊(yùn)
支撐這條生產(chǎn)線好的運(yùn)轉(zhuǎn)的，是黎明重工深耕礦機(jī)領(lǐng)域積累的自主創(chuàng)新成果。PE系列顎破采用應(yīng)力分布結(jié)構(gòu)，關(guān)鍵軸承部位壽命提升40%；CS系列圓錐破配備智能過(guò)鐵保護(hù)系統(tǒng)，整線配置的PLC集中控制系統(tǒng)，能實(shí)時(shí)監(jiān)控電機(jī)溫度、振動(dòng)幅度等20余項(xiàng)參數(shù)。
特別值得關(guān)注的是設(shè)備的節(jié)能表現(xiàn)：通過(guò)"以破代磨"工藝優(yōu)化，生產(chǎn)線噸礦電耗較行業(yè)標(biāo)準(zhǔn)降低18%；破碎腔內(nèi)襯采用合金復(fù)合材料，使耐磨件更換周期延長(zhǎng)至2000小時(shí)以上。這些創(chuàng)新既來(lái)源于黎明重工協(xié)同研發(fā)，也得益于其建立的"產(chǎn)學(xué)研用"一體化創(chuàng)新體系。
三、看得見(jiàn)的經(jīng)濟(jì)社會(huì)效益
投產(chǎn)后的運(yùn)營(yíng)數(shù)據(jù)印證了項(xiàng)目的成功：在每日16小時(shí)連續(xù)運(yùn)轉(zhuǎn)條件下，生產(chǎn)線保持年處理量超300萬(wàn)噸的穩(wěn)定輸出，成品中-16mm粒級(jí)占比達(dá)95%以上，完全滿足下游選礦工序要求。更難得的是，整線設(shè)備綜合故障率控制在0.5%以內(nèi)，遠(yuǎn)超同類項(xiàng)目水平。
經(jīng)濟(jì)效益方面，生產(chǎn)線創(chuàng)造的直接價(jià)值令人矚目：
得益于好的破碎工藝，礦石回收率提升12個(gè)百分點(diǎn)；
智能化運(yùn)維減少30%的人工巡檢頻次；
當(dāng)?shù)匦袠I(yè)專家評(píng)價(jià)道："這條生產(chǎn)線最可貴的是實(shí)現(xiàn)了經(jīng)濟(jì)效益與環(huán)境效益的雙贏，為貧礦資源開發(fā)提供了可復(fù)制的技術(shù)模板。"
河北承德鐵礦石項(xiàng)目就像一扇窗口，展示了黎明重工由設(shè)備供應(yīng)商向價(jià)值鏈整合者的轉(zhuǎn)型之路。當(dāng)智能化控制系統(tǒng)與重型破碎裝備更好融合，當(dāng)綠色制造理念滲透到每個(gè)生產(chǎn)環(huán)節(jié)，這條生產(chǎn)線已不僅是傳統(tǒng)意義上的加工設(shè)施，更是新時(shí)代礦業(yè)高質(zhì)量發(fā)展的鮮活注腳。
隨著"雙碳"戰(zhàn)略深入推進(jìn)，黎明重工正將承德項(xiàng)目的成功經(jīng)驗(yàn)復(fù)制到更多領(lǐng)域。
