這里是廣西百色時產(chǎn)150噸石灰石精品砂塔樓項目現(xiàn)場，原料為外購的石灰石。

成品為0-3mm精品砂，該項目是塔樓項目，投產(chǎn)至2023年9月已累計生產(chǎn)50多萬噸精品砂，成品主供中鐵項目。

1. 工藝布局對比

對比項	精品砂塔樓（VU150系統(tǒng)）	傳統(tǒng)制砂生產(chǎn)線
布局方式	塔樓式全封閉結構（占地≤500㎡）	平面開放式布局（占地≥2000㎡）
靈活性	模塊化設計，適用于城市/礦山	固定場地，搬遷困難
環(huán)保性	全封閉生產(chǎn)，粉塵噪聲≤國標	露天作業(yè)，需額外除塵措施

2. 成品質(zhì)量對比

指標	精品砂塔樓	傳統(tǒng)生產(chǎn)線
粒型	多棱體少，圓度好（國標Ⅰ類砂）	針片狀多（部分Ⅱ類砂）
級配	智能調(diào)控（0.6-3mm占比≥70%）	波動大，需人工調(diào)整
石粉含量	可控（5-10%可調(diào)）	易超標（10-15%常見）
MB值	＜1.0（低吸附性）	1.0-1.4（需額外處理）

3. 能耗與成本對比

項目	精品砂塔樓	傳統(tǒng)生產(chǎn)線
電耗	18-22kW·h/噸	25-30kW·h/噸
水耗	0（干法制砂）	2-3m³/噸（濕法需污水處理）
人工	2人/班（自動化）	5-8人/班
維護成本	耐磨件壽命長（如VSI轉子≥8萬噸）	錘頭/襯板更換頻繁

4. 環(huán)保與資源利用

維度	精品砂塔樓	傳統(tǒng)生產(chǎn)線
粉塵控制	脈沖除塵+負壓設計（排放＜10mg/m³）	水霧除塵（效果不穩(wěn)定）
石粉處理	回收用作建材填料	堆積或填埋（污染風險）
噪音	≤65dB（封閉降噪）	≥75dB（需隔音墻）

5. 適用場景

? 精品砂塔樓更適合：

高標基建（高鐵、核電等）
環(huán)保嚴查區(qū)域
土地受限的攪拌站配套

? 傳統(tǒng)生產(chǎn)線仍可考慮：

低標建材（如普通混凝土）
偏遠礦山（環(huán)保要求低）
投資預算有限的項目

結論

廣西百色項目通過干法塔樓工藝實現(xiàn)了：
? 質(zhì)量提升——滿足高鐵級砂石標準
? 成本優(yōu)化——節(jié)電30%、省人工60%
? 綠色低碳——零污水、粉塵超低排放
為石灰石高值化利用提供了工業(yè)化樣板，未來或成中小型砂廠升級首選方案。
