河南鄭州石灰石制砂生產(chǎn)線技術(shù)方案,VU120塔樓制砂機
一、項目背景
河南鄭州某預(yù)拌砂漿生產(chǎn)企業(yè)于2017年10月投產(chǎn)的石灰石制砂生產(chǎn)線，位于新密市曲梁鎮(zhèn)，采用黎明重工VU120骨料優(yōu)化系統(tǒng)，以外購石灰石為原料，生產(chǎn)符合國家標準的精品機制砂，更好預(yù)拌砂漿使用。該生產(chǎn)線以塔樓式全封閉設(shè)計為核心，解決了傳統(tǒng)制砂工藝中粒型差、含粉量高、污染大等問題，成為綠色智能制砂的標桿案例。
二、VU系統(tǒng)核心技術(shù)及設(shè)備配置
1. VU塔樓式集成系統(tǒng)架構(gòu)
VU系統(tǒng)采用垂直塔樓布局，整合破碎、整形、篩分、除塵、石粉控制等模塊，占地面積較傳統(tǒng)產(chǎn)線減少60%以上。本項目配置的VU120系統(tǒng)包含以下核心單元：
制砂整形主機：多級破碎腔結(jié)構(gòu)，實現(xiàn)石灰石"石打石"與"石打鐵"復(fù)合破碎，成品粒型圓潤，針片狀含量＜8%；
�？睾Y分系統(tǒng)：高頻振動篩與空氣篩分機聯(lián)動，精確控制成品砂0.075-4.75mm區(qū)間級配，細度模數(shù)可調(diào)（2.3-3.1）；
VU粒優(yōu)機：通過高速渦流空氣選粉，將石粉含量穩(wěn)定控制在5%-15%；
加濕攪拌模塊（選配）：智能調(diào)節(jié)含水率至3%-5%，滿足預(yù)拌砂漿對砂料流動性的要求。
2. 環(huán)保與能效設(shè)計
脈沖除塵系統(tǒng)：采用三級過濾（旋風+布袋+活性炭），粉塵排放濃度＜20mg/m³；
噪聲控制：塔樓全封閉+復(fù)合隔音材料，廠界噪聲＜65dB；
循環(huán)利用：90%以上工藝水回用，石粉收集后可作為砂漿摻合料。
3. 智能化控制系統(tǒng)
配備PLC更好控制臺，實時監(jiān)測產(chǎn)能、能耗、設(shè)備狀態(tài)等數(shù)據(jù)；
聯(lián)動調(diào)節(jié)破碎機轉(zhuǎn)速、篩分角度等參數(shù)，確保成品砂質(zhì)量穩(wěn)定。
三、生產(chǎn)指標與優(yōu)勢分析
指標類別 參數(shù)/效果 傳統(tǒng)工藝對比
生產(chǎn)能力 時產(chǎn)120-150噸成品砂 提升40%
成品質(zhì)量 細度模數(shù)2.8±0.2，MB值≤1.0 級配連續(xù)性提高35%
能耗 單噸電耗≤8kWh 降低25%
用地 系統(tǒng)占地約15m×20m 節(jié)省60%場地
環(huán)保達標 達到GB/T 14684-2022標準 無污水外排、粉塵超低排放
核心優(yōu)勢：
砂質(zhì)提升：粒型接近天然砂，壓碎值≤20%，砂漿抗壓強度提高15%-20%；
成本優(yōu)化：石粉增值利用，每噸砂綜合成本降低18-25元；
快速部署：模塊化設(shè)計，從安裝到投產(chǎn)僅需45天。
四、行業(yè)應(yīng)用拓展
該方案不僅適用于石灰石，還可適配花崗巖（需調(diào)整耐磨件材質(zhì)）、尾礦等原料，典型應(yīng)用場景包括：
預(yù)拌砂漿領(lǐng)域：控制石粉含量5%-10%，替代30%-50%天然砂；
混凝土攪拌站：生產(chǎn)II類及以上標準機制砂；
干混砂漿一體化項目：與砂漿生產(chǎn)線無縫對接。
