石灰石資源好的利用與砂石產業鏈升級路徑——以廣西武宣時產350噸骨料項目為例

一、石灰石特性與產業適配性

資源稟賦

碳酸鈣含量＞90%，莫氏硬度3，中國探明儲量超千億噸（廣西占比12.7%）

武宣礦區屬低硫高鈣礦，破碎后針片狀含量＜10%，特別適配機制砂生產

 

加工優勢

 

節能環保：干法工藝粉塵排放＜20mg/m³，石粉回收率＞95%

經濟性：自有礦山使原料成本降低35%，機制砂級配可調減少水泥用量

二、制砂機的核心作用與技術創新

功能突破

替代天然砂資源，VSI6X制砂機成品砂細度模數可控（2.4-3.0）

層壓破碎技術（HPC220）使混凝土抗壓強度提升15%

工藝革新

"顎破+圓錐破+制砂機"組合能耗較傳統工藝降低30%

配套脈沖除塵與智能篩分系統，實現綠色生產認證

三、武宣項目長效性驗證與行業啟示

 

設備表現

HPC220液壓圓錐破十年無大修，壽命周期成本僅為同類60%

2023年參數優化后產能提升至380噸/時

產業鏈價值

2024年西南地區機制砂價格較天然砂低20%，市場滲透率超65%

智能控制系統（如AI粒形監測）進一步降低人工干預
