貴州某集團以"逢山開路、遇水架橋"的使命擔當，參與國家重大交通工程建設。黔西南納晴高速項目作為貴州省"十四五"交通規(guī)劃的重點工程，連接納雍與晴隆兩縣，全長約160公里，途經喀斯特地貌核心區(qū)，地形險峻、地質條件復雜。項目建成后，將極大改善黔西南地區(qū)的交通條件，促進區(qū)域經濟發(fā)展與鄉(xiāng)村振興。
在項目建設中，砂石骨料作為核心基礎材料，其質量與供應穩(wěn)定性直接影響工程進度與質量。貴州某集團憑借豐富的工程經驗，與世邦集團、黎明重工等行業(yè)實踐企業(yè)展開深度合作，共同打造了一條好的、環(huán)保、智能的石灰石破碎生產線，為項目提供了可靠的骨料保障。
二、項目挑戰(zhàn)與解決方案
（一）核心挑戰(zhàn)
原料特性復雜：項目所用石灰石硬度高（莫氏硬度4-5）、含泥量較高，對破碎設備的耐磨性能與處理能力提出嚴苛要求。
環(huán)保與能耗約束：項目位于生態(tài)敏感區(qū)，需滿足嚴格的粉塵排放與噪音控制標準；同時，高產能需求下需優(yōu)化能耗效率。
工藝適配性要求：高速公路對骨料粒型、級配要求極高，需確保成品骨料針片狀含量低、級配連續(xù)。
（二）技術方案
針對以上挑戰(zhàn)，世邦集團與黎明重工聯合提供了定制化解決方案：
設備配置：采用"顎破+反擊破+沖擊破"三段破碎工藝，搭配振動篩分系統(tǒng)。具體設備包括：GF1245振動給料機、PE750×1060顎式破碎機（黎明重工）、PF1315反擊式破碎機（世邦）、VSI5X1145沖擊式破碎機（世邦）、S5X2460-3振動篩（世邦）。
工藝設計：通過多級破碎與篩分組合，實現物料的精細化處理。顎破進行粗碎，反擊破中碎整形，沖擊破制砂并進一步優(yōu)化粒型，振動篩實現精準分級。
黎明重工為此項目量身定制了模塊化生產線方案，核心配置包括GF系列重型給料機、PE系列深腔顎式破碎機、PF系列硬巖反擊破、VSI5X高性能制砂機以及S5X系列好的振動篩。該配置充分發(fā)揮了"粗碎-中碎-細碎-整形"的工藝優(yōu)勢，形成完整的閉路循環(huán)系統(tǒng)。
特別是VSI5X制砂機采用了獨特的石打石與石打鐵組合破碎原理，通過精確控制的破碎腔物料撞擊角度，使成品砂的粒形呈規(guī)則的多棱體，細度模數可穩(wěn)定控制在標準范圍內。設備配備的液壓開蓋裝置和在線監(jiān)測系統(tǒng)，大大縮短了維護時間，確保生產連續(xù)性。生產線整體搭載了智能控制系統(tǒng)，可實時監(jiān)測設備運行參數、自動調節(jié)給料速度，當檢測到異常振動或溫度升高時，會立即啟動保護程序并發(fā)出預警。
四、實施成效與技術創(chuàng)新
項目實施后，生產線展現出顯著的技術優(yōu)勢：首先，產能完全達到設計要求，各級骨料成品合格率大幅提升；其次，設備運行穩(wěn)定性突出，關鍵部件采用了特殊耐磨材料，使用壽命延長；更重要的是，整條生產線采取了多重防塵降噪措施，工作環(huán)境粉塵濃度遠低于國家排放標準。
在工藝流程方面，黎明重工創(chuàng)新采用"預先篩分+選擇性破碎"技術，通過在粗碎前設置預篩分環(huán)節(jié)，將原料中的泥土和細小顆粒提前分離，既減輕了后續(xù)設備的負荷，又提高了破碎效率。針對石灰石特性優(yōu)化的破碎腔型設計，有效降低了針片狀顆粒含量，產出的機制砂完全滿足高標準混凝土的用砂需求。生產線還實現了水循環(huán)系統(tǒng)的零排放，清洗骨料的廢水經沉淀處理后重復利用，體現了綠色發(fā)展的理念。
