一、項(xiàng)目背景及地理環(huán)境
新疆烏恰縣某鐵礦礦區(qū)位于中國(guó)與吉爾吉斯斯坦邊境30公里范圍內(nèi)，地理坐標(biāo)為東經(jīng)75°15′，北緯39°42′。礦區(qū)平均海拔3200米，年均氣溫僅3.5℃，冬季最低溫可達(dá)-30℃，年降水量不足200mm，氧含量約為平原地區(qū)的65%，屬于典型的高寒干旱礦區(qū)環(huán)境。
二、礦石性質(zhì)分析
礦物組成：
主要礦物：赤鐵礦（Fe?O?）含量58%以上
次要礦物：石英（SiO?）20-25%，菱鐵礦5-8%
微量礦物：含少量釩、鈦等有價(jià)元素
三、破碎工藝流程設(shè)計(jì)
（1）工藝流程選擇依據(jù)
考慮到高海拔環(huán)境特點(diǎn)和礦石特性，采用三段一閉路破碎流程，工藝流程如下：
原礦→粗碎（顎破）→中碎（圓錐破）→篩分→細(xì)碎（圓錐破）→成品
（2）主要工藝參數(shù)
工藝段 設(shè)備類型 進(jìn)料粒度 排料粒度 處理能力
粗碎 顎式破碎機(jī) ≤650mm ≤200mm 180t/h
中碎 單缸圓錐破 ≤200mm ≤50mm 150t/h
細(xì)碎 多缸圓錐破 ≤50mm ≤25mm 120t/h
（3）特殊情況處理
高原適應(yīng)性改造：
設(shè)備動(dòng)力系統(tǒng)增加30%功率冗余
使用低溫型液壓油（-40℃規(guī)格）
電氣系統(tǒng)防結(jié)露處理
四、核心設(shè)備選型
粗碎設(shè)備：
型號(hào)：顎式破碎機(jī)
特點(diǎn)：深V型破碎腔，鑄鋼結(jié)構(gòu)機(jī)架
中細(xì)碎設(shè)備：
中碎：?jiǎn)胃滓簤簣A錐破
細(xì)碎：多缸液壓圓錐破
共同特點(diǎn)：
液壓清腔系統(tǒng)
耐磨襯板壽命
五、高原環(huán)境特殊措施
設(shè)備改造：
液壓系統(tǒng)加熱裝置
電氣柜保溫防潮處理
該方案充分考慮了烏恰鐵礦的高原特性和礦石特點(diǎn)，通過(guò)科學(xué)合理的工藝設(shè)計(jì)和設(shè)備選型，確保在惡劣環(huán)境下實(shí)現(xiàn)穩(wěn)定好的的鐵礦石加工生產(chǎn)。項(xiàng)目投產(chǎn)后的實(shí)際運(yùn)行數(shù)據(jù)可為類似高海拔礦區(qū)開(kāi)發(fā)提供重要參考。
