褐煤，又名柴煤，是煤化程度最低的礦產(chǎn)煤。一種介于泥炭與瀝青煤之間的棕黑色、無光澤的低級煤。化學(xué)反應(yīng)性強(qiáng)，在空氣中容易風(fēng)化，不易儲(chǔ)存和運(yùn)輸，燃燒時(shí)對空氣污染嚴(yán)重。但是由于更好煤幾乎被采空，褐煤已成為我國主要使用的煤，但由于褐煤的煤化程度太低，造成燃燒時(shí)會(huì)有大量的黑灰飄在空中，如果不經(jīng)過洗煤處理和提煉，大量使用劣勢褐煤會(huì)導(dǎo)致我國霧霾問題日益嚴(yán)重。

作為煉焦過程中的一個(gè)重要化產(chǎn)回收產(chǎn)品，煤焦油是一個(gè)組分上萬種的復(fù)雜混合物，已從中分離并認(rèn)定的單種化合物約500余種，約占煤焦油總量的55%，其中包括苯、二甲苯、萘等174種中性組分；酚、甲酚等63種酸性組分和113種堿性組分。煤焦油中的很多化合物是塑料、合成纖維、合成橡膠、農(nóng)藥、醫(yī)藥、耐高溫材料及國防工業(yè)的貴重原料，也有一部分多環(huán)芳烴化合物是石油化工所不能生產(chǎn)和替代的。煤焦油主要用來加工生產(chǎn)輕油、酚油、萘油及改質(zhì)瀝青等，再經(jīng)深加工后制取苯、酚、萘、蒽等多種化工原料，產(chǎn)品數(shù)量眾多、用途十分廣泛。而固體熱載體法快速熱解煤氣為中熱值煤氣，可用作城市煤氣、工業(yè)燃料，也可以用作化工原料。

煤炭破碎機(jī)是針對煤炭行業(yè)現(xiàn)狀推出的一款新型專屬設(shè)備，低耗是它的顯著特點(diǎn)。黎明重工研發(fā)生產(chǎn)的煤炭破碎機(jī)屬于無篩底粉碎機(jī)，干濕物料均可粉碎，因而粉碎范圍非常廣泛，比如煤炭、煤矸石、爐渣等多種物料。經(jīng)由煤炭破碎機(jī)粉碎的成品粒度均勻，粒形更標(biāo)準(zhǔn)，級配合理，可以控制在2mm（毫米）以下。

我國露天煤礦開采技術(shù)水平已接近于國際較高水平，特別是一些大型的露天煤礦，如中煤集團(tuán)平朔安太堡露天煤礦，采用新型的半連續(xù)開采工藝：單斗電鏟采掘—移動(dòng)破碎站—膠帶運(yùn)輸系統(tǒng)。這種工藝適應(yīng)性強(qiáng)、優(yōu)點(diǎn)突出，已成為露天煤礦開采工藝的一個(gè)重要技術(shù)發(fā)展方向。

褐煤首先其水分很高，一般到廠的原料水分都高達(dá)30%左右。其次褐煤的揮發(fā)分很高，高達(dá)40%以上，燃點(diǎn)低，易于燃燒，故在粉磨工序中我們必須特別注意系統(tǒng)的溫度控制。再次，褐煤的熱值非常低，綜合以上因素，我們更多立式磨粉機(jī)用于粉磨褐煤。

常用加工設(shè)備：中速磨煤機(jī)，歐版磨粉機(jī)

褐煤介紹與磨粉流程

以空氣為干燥介質(zhì)的褐煤烘干機(jī)在引風(fēng)機(jī)的作用下與熱源行成對流加熱方式，使褐煤與高濕負(fù)壓進(jìn)入烘干機(jī)內(nèi)進(jìn)行傳質(zhì)、傳熱交換。濕褐煤以攪動(dòng)分散粉碎褐煤的運(yùn)行方式緩緩振動(dòng)向前移動(dòng)并排出烘干滾筒，完成干燥褐煤過程。干燥后的褐煤主要用于發(fā)電廠的燃料，也可作化工原料、催化劑載體、吸附劑、凈化污水和回收金屬等。

 黎明重工經(jīng)過多年研究和試驗(yàn)，研發(fā)出專門針對清潔煤粉制備的相關(guān)裝備及工藝，適用于無煙煤、煙煤和褐煤，煤粉細(xì)度調(diào)節(jié)準(zhǔn)確，運(yùn)行穩(wěn)定，低耗能高產(chǎn)出，防爆性能可靠，贏得了客戶的大量回頭訂單和廣泛贊譽(yù)。

我們可以提供清潔煤粉制備生產(chǎn)線設(shè)備總包、交鑰匙工程總包（EPC）等服務(wù)，包含：工程項(xiàng)目的設(shè)計(jì)、設(shè)備采購與制造、施工、試運(yùn)行服務(wù)等工作。

高爐噴吹煤粉系統(tǒng)在電力、鋼鐵、冶金行業(yè)有著非常廣泛的用途。在整個(gè)系統(tǒng)中，粉煤的制備是重要的環(huán)節(jié)，原煤經(jīng)加工形成的煤粉質(zhì)量決定著整套系統(tǒng)的運(yùn)行效率。因?yàn)槊悍垡蟾撸a(chǎn)量大，傳統(tǒng)磨煤機(jī)無法滿足其要求。于是，越來越多的客戶將目光轉(zhuǎn)向了新型磨煤機(jī)。

MTW系列歐版磨升級加強(qiáng)版經(jīng)三十余年技術(shù)沉淀，吸收歐洲粉磨理念，厚積薄發(fā)，實(shí)現(xiàn)了工業(yè)磨粉機(jī)的技術(shù)革命，擁有多項(xiàng)自主專利技術(shù)產(chǎn)權(quán)，投放市場以來，通過多項(xiàng)科技成果鑒定，成為傳統(tǒng)雷蒙磨、擺式磨以及球磨機(jī)更新?lián)Q代產(chǎn)品，大型礦物規(guī)模化建廠必選裝備。
