江蘇連云港花崗巖制砂生產(chǎn)線,江蘇花崗巖制砂生產(chǎn)線

1. 項(xiàng)目概述
位置：江蘇連云港連云區(qū)板橋街道
    建設(shè)背景：建材公司配套攪拌站項(xiàng)目，主要用于生產(chǎn)高品質(zhì)砂石骨料
    物料性質(zhì)：外購花崗巖（進(jìn)料粒度 ≤700mm）
    成品規(guī)格：
        機(jī)制砂：0-5mm
        普通骨料：5-10mm、10-16mm、16-26mm
        精品骨料：部分高強(qiáng)度碎石
    產(chǎn)量：250噸/小時(shí)
    用途：商砼（商品混凝土）+ 零售

這里是2023年9月江蘇連云港花崗巖碎石制砂生產(chǎn)線回訪現(xiàn)場。該項(xiàng)目位于連云區(qū)板橋街道，是建設(shè)工程公司攪拌站配套項(xiàng)目，加工物料為外購的花崗巖，成品為砂石骨料，主要用于生產(chǎn)混凝土和零售。該生產(chǎn)線主要設(shè)備來自黎明重工，PE900*1200鄂式破碎機(jī)、HST250單缸液壓圓錐破碎機(jī)、HPT300多缸液壓圓錐破碎機(jī)破碎，VSI5X1145制砂機(jī)整形制砂，圓振動篩篩分，綜合時(shí)產(chǎn)250噸左右。

3. 生產(chǎn)線亮點(diǎn)
適配花崗巖特性：HST/HPT液壓圓錐破組合增強(qiáng)硬巖破碎效率，降低磨損成本
精細(xì)化篩分：多臺S5X振動篩協(xié)同作業(yè)，精準(zhǔn)分級4種規(guī)格骨料+機(jī)制砂
智能控制：集中電控系統(tǒng)，實(shí)現(xiàn)流程自動化監(jiān)測與調(diào)節(jié)
環(huán)保達(dá)標(biāo)：配備除塵降噪措施，符合江蘇地區(qū)環(huán)保要求
4. 成品應(yīng)用 & 效益

機(jī)制砂（0-5mm）：用于C30以上高標(biāo)號混凝土
骨料（5-26mm）：商砼攪拌站自用+對外銷售
經(jīng)濟(jì)效益：
        設(shè)備運(yùn)行穩(wěn)定，維護(hù)成本低（HPT圓錐破易損件壽命提升30%）
        成品粒形優(yōu)異，市場溢價(jià)能力顯著

5. 工藝深化解析

該生產(chǎn)線采用"三段一閉路"好的破碎流程，粗碎環(huán)節(jié)PE900×1200顎破配備液壓調(diào)整排料口裝置，可快速應(yīng)對不同進(jìn)料尺寸變化；中細(xì)碎階段HST250與HPT300形成梯度破碎體系，前者實(shí)現(xiàn)85-160mm物料的中碎預(yù)處理，后者雙機(jī)并聯(lián)確保＜60mm物料的細(xì)碎通過率提升40%。VSI5X1145制砂機(jī)采用專利的"四口轉(zhuǎn)子+周護(hù)板"結(jié)構(gòu)，通過調(diào)整轉(zhuǎn)速（45-60m/s）可實(shí)現(xiàn)機(jī)制砂細(xì)度模數(shù)2.4-3.0的精準(zhǔn)控制。
6. 環(huán)保與智能化

項(xiàng)目配置了旋風(fēng)除塵+脈沖布袋除塵雙重系統(tǒng)，粉塵排放＜20mg/m³；篩分機(jī)組采用橡膠彈簧減振技術(shù)，噪聲控制＜75dB。智能化方面通過PLC更好控制系統(tǒng)實(shí)現(xiàn)三大關(guān)鍵優(yōu)化：
1）基于電流檢測的自動給料調(diào)節(jié)
2）圓錐破腔型磨損實(shí)時(shí)監(jiān)測
3）制砂機(jī)潤滑系統(tǒng)溫度連鎖保護(hù)
7. 市場競爭力分析

該生產(chǎn)線成品機(jī)制砂MB值＜1.0，石粉含量可控在7-10%，特別適合高標(biāo)準(zhǔn)商用混凝土生產(chǎn)。16-26mm精品骨料壓碎指標(biāo)＜12%，已穩(wěn)定供應(yīng)連云港跨海大橋等重點(diǎn)項(xiàng)目。對比傳統(tǒng)產(chǎn)線，該方案噸能耗降低15%，得益于HPT300的液壓系統(tǒng)節(jié)能設(shè)計(jì)和VSI5X的深腔轉(zhuǎn)子優(yōu)化。
