石灰石制砂機應用-蘇州時產(chǎn)450噸石灰石碎石項目
一、項目背景
江蘇蘇州某建材公司為配合當?shù)鼗A設施建設，在沛縣楊屯鎮(zhèn)新建一條時產(chǎn)450噸的石灰石碎石生產(chǎn)線，選用世邦集團全套破碎篩分設備。該生產(chǎn)線主要為自營攪拌站供應更好砂石骨料，同時滿足周邊建筑市場需求。
二、核心設備選型與工藝流程
1. 粗碎階段：C6X125顎式破碎機
處理能力：450-500t/h
進料粒度：≤750mm
出料粒度：≤200mm
特點：采用重型機架和高錳鋼顎板，適應高硬度石灰石破碎，使用壽命長。
2. 中碎階段：PFW1318+CI5X1520反擊式破碎機
組合優(yōu)勢：兩級反擊破串聯(lián)，實現(xiàn)好的中碎，減少過粉碎現(xiàn)象。
出料粒度：≤50mm
特點：
液壓開蓋裝置，便于檢修；
高鉻板錘，耐磨性強，降低維護成本。
3. 制砂階段：VSI6X1150沖擊式破碎機
技術亮點：
四口葉輪設計：破碎效率較傳統(tǒng)三口葉輪提升20%；
深腔型轉(zhuǎn)子：增強物料通過能力，成砂率提高15%；
耐磨件優(yōu)化：關鍵部件壽命延長30%-200%。
成品砂規(guī)格：0-5mm（細度模數(shù)可調(diào)）；
應用效果：砂粒形圓潤，級配連續(xù)，符合攪拌站高標準用砂需求。
4. 篩分系統(tǒng)：多層圓振動篩
分級精度：精確分離0-5mm、5-10mm、10-20mm三種規(guī)格骨料；
閉路循環(huán)：超粒徑物料返回破碎，提升資源利用率。
三、生產(chǎn)線優(yōu)勢分析
成本控制：
骨料自產(chǎn)自用，綜合成本較外購降低25%；
VSI6X1150沖擊破節(jié)能設計，噸電耗減少15%。
品質(zhì)保障：
成品骨料針片狀含量＜8%，優(yōu)于國標（≤15%）；
砂石級配優(yōu)化，提升混凝土強度和易性。
智能運維：
設備配備遠程監(jiān)控系統(tǒng)，實時反饋運行數(shù)據(jù)；
自動化潤滑裝置，減少人工干預。
四、運行效益
產(chǎn)能：穩(wěn)定達到450t/h，峰值500t/h；
經(jīng)濟效益：年節(jié)省外購骨料費用超600萬元；
社會效益：支持沛縣漢文化景區(qū)及交通基建，推動區(qū)域發(fā)展。
五、項目擴展價值
技術可復制性：適用于高硬度巖石（如花崗巖、玄武巖）破碎制砂；
環(huán)保貢獻：生產(chǎn)線封閉設計，粉塵排放＜20mg/m³，符合綠色礦山標準；
市場前景：為長三角地區(qū)砂石骨料集約化生產(chǎn)提供范本。
結(jié)語
該生產(chǎn)線通過“顎破+反擊破+沖擊破”的好的組合，搭配VSI6X1150沖擊破的先進制砂技術，實現(xiàn)了石灰石資源的高值化利用。2023年9月回訪顯示，設備運行穩(wěn)定，客戶滿意度高，未來可進一步推廣至類似項目。
