老撾鐵礦石選礦項目是一個年產(chǎn)120萬噸的中型鐵礦石加工項目，位于中南半島北部的瑯勃拉邦地區(qū)。該項目礦區(qū)面積為500公頃，鐵礦石平均品位為45%，主要礦物成分為磁鐵礦和赤鐵礦的混合礦，采用了國際化標準的設(shè)計和建設(shè)方案。

在設(shè)備選型方面，該項目創(chuàng)新性地采用了"三段破碎+兩段磨礦"的工藝流程：

    粗碎階段：

    配置2臺C6X160顎式破碎機
    入料粒度：0-800mm
    出料粒度：0-250mm
    單機產(chǎn)能：280t/h

    中碎階段：

    選用3臺HST315單缸液壓圓錐破
    出料粒度：0-75mm
    單機產(chǎn)能：180t/h
    配備液壓調(diào)節(jié)系統(tǒng)，可實現(xiàn)粒度在線調(diào)整

    細碎階段：

    配備4臺HPT300多缸液壓圓錐破
    出料粒度：0-25mm
    單機產(chǎn)能：120t/h
    配備智能控制系統(tǒng)，自動優(yōu)化破碎參數(shù)

    篩分系統(tǒng)：

    采用8臺S5X3075-3T圓振動篩
    篩分效率＞90%
    分級精度±2mm

值得注意的是，該項目采用了世邦節(jié)能技術(shù)：

    全系統(tǒng)配備變頻控制，能耗降低15%
    采用水循環(huán)系統(tǒng)，實現(xiàn)95%的水資源回用

該項的建成投產(chǎn)，為當?shù)貏?chuàng)造300個直接就業(yè)崗位，并帶動運輸、維修等配套產(chǎn)業(yè)發(fā)展。
