山東臨沂花崗巖碎石制砂生產(chǎn)線，臨沂花崗巖制砂機(jī)

一、項(xiàng)目背景
在山東臨沂平邑縣的花崗巖礦山地質(zhì)環(huán)境治理區(qū)，一座好的、環(huán)保的花崗巖碎石制砂生產(chǎn)線成功投產(chǎn)并穩(wěn)定運(yùn)行。該項(xiàng)目是在原有花崗巖礦山修復(fù)基礎(chǔ)上的資源化利用工程，旨在實(shí)現(xiàn)對(duì)廢棄石料的綠色加工，同時(shí)兼顧生態(tài)修復(fù)，"礦山治理+砂石生產(chǎn)"可持續(xù)發(fā)展模式。

二、綜合治理與資源再生
本項(xiàng)目嚴(yán)格依照《花崗巖礦山地質(zhì)環(huán)境治理工程設(shè)計(jì)方案》實(shí)施，分兩階段推進(jìn)生態(tài)修復(fù)：

    一期工程（2020.4-2020.10）：治理面積290畝，完成危巖清理、廢石渣外運(yùn)及場(chǎng)地平整；
    二期工程（2021.4起）：擴(kuò)展至647畝，深化邊坡防護(hù)、栽種側(cè)柏及播撒草種，實(shí)現(xiàn)礦區(qū)復(fù)綠。

創(chuàng)新點(diǎn)：礦山修復(fù)過程中產(chǎn)生的花崗巖尾料（原廢棄石渣）被重新利用，通過好的破碎制砂設(shè)備轉(zhuǎn)化為精品砂石骨料（0-5mm、5-10mm規(guī)格）及鐵路道砟石（10-31.5mm），資源綜合利用率超95%。

三、核心設(shè)備與工藝流程
1. 主要設(shè)備配置（均由世邦集團(tuán)提供）

    粗碎階段：1臺(tái)C6X145顎式破碎機(jī) —— 處理大塊花崗巖（進(jìn)料粒度≤1100mm），抗壓強(qiáng)度達(dá)300MPa；
    中細(xì)碎階段：HST315單缸圓錐破+3臺(tái)HPT300多缸圓錐破 —— 層壓破碎技術(shù)保障成品低針片狀率（<8%）；
    制砂整形：VSI6X1263立軸沖擊破 —— 采用四口轉(zhuǎn)子設(shè)計(jì)，成品砂細(xì)度模數(shù)可調(diào)（2.4-3.0）；
    篩分分級(jí)：5臺(tái)S5X圓振動(dòng)篩 —— 多規(guī)格同步篩分，篩分效率≥90%。

2. 產(chǎn)能與成品

    時(shí)產(chǎn)600噸，年產(chǎn)能可達(dá)150萬噸（按年工作250天計(jì)）；
    成品應(yīng)用：
        精品骨料 → 商混站、預(yù)制構(gòu)件
        道砟石 → 鐵路、公路路基

四、環(huán)保與經(jīng)濟(jì)雙效益

    環(huán)境效益
        消除礦區(qū)滑坡隱患，植被覆蓋率恢復(fù)至60%以上；
        全封閉生產(chǎn)線配置脈沖除塵系統(tǒng)，粉塵排放<10mg/m³，優(yōu)于國(guó)標(biāo)。
   

五、行業(yè)示范意義
該項(xiàng)目為廢棄礦山資源化利用提供了可復(fù)制方案：

    工藝借鑒：高硬度花崗巖更多"顎破+多缸圓錐破+立軸制砂"組合；
    模式參考：將生態(tài)修復(fù)與砂石生產(chǎn)綁定，實(shí)現(xiàn)政策合規(guī)與更好雙贏。

目前，生產(chǎn)線設(shè)備運(yùn)行穩(wěn)定，客戶反饋噸能耗節(jié)約15%。如需詳細(xì)技術(shù)參數(shù)或參觀案例現(xiàn)場(chǎng)，歡迎隨時(shí)聯(lián)系！
