與新疆鵝卵石項目相比，采用"顎破+圓錐破+立軸制砂機"的經(jīng)典配置，引入多缸液壓圓錐破作為中碎設(shè)備，其層壓破碎原理使鵝卵石的針片狀含量降低15%，配合VSI6X制砂機的"石打石"破碎模式，最終成品含粉量控制在5%-7%的理想?yún)^(qū)間。這種工藝組合在廣西水利樞紐工程中獲得驗證，生產(chǎn)的機制砂壓碎值低于20%，MB值小于1.0，達到Ⅱ類建設(shè)用砂標準。

核心制砂裝備技術(shù)解析：

VSI6X立軸沖擊式制砂機：作為貴港項目的設(shè)備，采用四口拋料頭設(shè)計配合深腔型轉(zhuǎn)子，破碎效率較傳統(tǒng)機型提升30%；獨有的液壓開蓋裝置使檢修工時縮短至4小時內(nèi)，搭載智能潤滑系統(tǒng)實現(xiàn)軸承溫度實時監(jiān)控。該機型在鵝卵石制砂中展現(xiàn)出顯著優(yōu)勢，成品砂的細度模數(shù)可精確控制在2.4-2.8之間。

5X制砂機系列：采用組合式拋料頭設(shè)計，耐磨件使用壽命延長40%，特別適合含硅量高的礦石處理。云南大理花崗巖制砂項目實踐顯示，其噸鋼耗可低至0.18kg/噸，較行業(yè)平均水平節(jié)能15%。

移動式制砂系統(tǒng)：集成VSI系列制砂機與多層振動篩，實現(xiàn)現(xiàn)場砂石聯(lián)產(chǎn)。在雄安新區(qū)建設(shè)中，該設(shè)備創(chuàng)下單日處理建筑再生骨料2000噸的記錄。

廣西貴港平南縣鵝卵石制砂生產(chǎn)線采用黎明重工全套破碎制砂設(shè)備，核心配置包括：

    PE600×900顎式破碎機（粗碎）
    HPT300多缸液壓圓錐破碎機（中碎）
    VSI6X1150制砂機（細碎整形）

項目亮點：
好的三級破碎：時產(chǎn)200噸，成品砂粒形圓潤，級配合理，符合Ⅱ類建筑用砂標準（壓碎值＜20%，MB值＜1.0）。
綠色環(huán)保：結(jié)合當?shù)伫Z卵石資源及水路運輸優(yōu)勢，降低開采及物流成本，助力可持續(xù)發(fā)展。
工藝優(yōu)化：多缸液壓圓錐破使針片狀含量降低15%，VSI6X制砂機實現(xiàn)石打石破碎，含粉量穩(wěn)定在5%-7%。

對比案例：新疆鵝卵石項目采用相同工藝，進一步驗證了黎明重工設(shè)備的穩(wěn)定性和適應(yīng)性。

自1987年成立以來，黎明重工已發(fā)展成為全球化的礦山機械制造商，產(chǎn)品遠銷130多個國家，年產(chǎn)3000臺套重型設(shè)備。

設(shè)備技術(shù)：

    VSI6X立軸沖擊式制砂機
        四口拋料頭+深腔轉(zhuǎn)子，破碎效率提升30%
        液壓開蓋設(shè)計，4小時內(nèi)完成檢修
        智能潤滑系統(tǒng)，實時監(jiān)控軸承溫度

    5X系列好的制砂機
        組合式拋料頭，耐磨件壽命延長40%
        噸鋼耗低至0.18kg，節(jié)能15%
