應用方案貴州遵義高速公路制砂生產線
一、項目背景
重遵高速擴容項目作為西南地區重要交通樞紐工程，橋隧占比高達71.67%，對高品質砂石骨料的粒形、級配及抗壓強度提出嚴苛要求。項目地處貴州喀斯特地貌區，石灰石資源豐富但成分復雜，亟需好的破碎設備實現資源轉化與品質升級。
二、設備配置與技術方案
世邦集團為該項目定制了“GF0942振動給料機+PE600×900顎式破碎機+PF1214反擊式破碎機+VSI7611沖擊破整形機+S5X2160-4振動篩”的全流程解決方案，綜合時產達120噸，可穩定生產0-5mm、5-10mm、10-20mm等多規格成品骨料，滿足混凝土澆筑及道路基層施工需求。
GF0942振動給料機：均勻喂料，最大進料粒度≤500mm，有效避免堵塞。
PE600×900顎式破碎機：粗碎核心設備，處理能力80-240噸/小時，抗壓強度≤320MPa。
PF1214反擊式破碎機：中細碎及粒形優化，成品針片狀含量≤10%。
VSI7611沖擊破整形機：石打石工藝，制砂效率高，成品砂含泥量≤3%。
S5X2160-4振動篩：4層篩分設計，篩分效率≥85%，確保級配精準。
三、技術創新亮點
地質適配性設計
采用高錳鋼+鉻合金復合材質錘頭，耐腐蝕性較普通碳鋼提升3倍，適應喀斯特地貌石灰石高硅含量特性。
配置懸掛式磁選機+永磁滾筒，雙重除鐵工藝去除雜質，保障骨料純凈度，避免混凝土中鐵元素銹蝕風險。
智能運維系統
搭載物聯網監控模塊，實時采集設備振動值、軸承溫度、電流等參數，，提前預警并生成維護方案。
支持遠程診斷，專家可異地調取數據并指導維修，故障響應時間縮短至2小時內，較傳統模式提升75%。
綠色生產優化
全封閉生產系統+脈沖除塵器，粉塵排放濃度≤30mg/m³，優于國家標準。
濕法制砂工藝結合細砂回收系統，砂料回收率達95%，水資源循環利用率≥80%。
四、應用效果與行業價值
產能與品質：生產線穩定運行超3000小時，成品骨料壓碎值≤18%，針片狀含量≤8%，完全滿足高速公路C60混凝土用砂標準。
經濟效益：設備故障率≤0.5%，維護成本降低20%，單位電耗較傳統方案節省18%。
行業示范：該方案已推廣至西南山區多個基建項目，累計處理石灰石超5000萬噸，為復雜地質條件下的資源開發提供標桿案例。
世邦集團憑借“破碎-制砂-篩分-環保”一體化解決方案，成功助力重遵高速擴容項目突破骨料生產瓶頸，以技術創新推動交通基建高質量發展。未來，世邦將持續深耕綠色智能破碎技術，為更多國家重點工程提供可靠裝備支持。
