褐煤介绍与磨粉流程

以空气为干燥介质的褐煤烘干机在引风机的作用下与热源行成对流加热方式，使褐煤与高湿负压进入烘干机内进行传质、传热交换。湿褐煤以搅动分散粉碎褐煤的运行方式缓缓振动向前移动并排出烘干滚筒，完成干燥褐煤过程。干燥后的褐煤主要用于发电厂的燃料，也可作化工原料、催化剂载体、吸附剂、净化污水和回收金属等。

褐煤，又名柴煤，是煤化程度更低的矿产煤。一种介于泥炭与沥青煤之间的棕黑色、无光泽的低级煤。化学反应性强，在空气中容易风化，不易储存和运输，燃烧时对空气污染严重。但是由于很好煤几乎被采空，褐煤已成为我国主要使用的煤，但由于褐煤的煤化程度太低，造成燃烧时会有大量的黑灰飘在空中，如果不经过洗煤处理和提炼，大量使用劣势褐煤会导致我国雾霾问题日益严重。

作为炼焦过程中的一个重要化产回收产品，煤焦油是一个组分上万种的复杂混合物，已从中分离并认定的单种化合物约500余种，约占煤焦油总量的55%，其中包括苯、二甲苯、萘等174种中性组分；酚、甲酚等63种酸性组分和113种碱性组分。煤焦油中的很多化合物是塑料、合成纤维、合成橡胶、农药、医药、耐高温材料及国防工业的贵重原料，也有一部分多环芳烃化合物是石油化工所不能生产和替代的。煤焦油主要用来加工生产轻油、酚油、萘油及改质沥青等，再经深加工后制取苯、酚、萘、蒽等多种化工原料，产品数量众多、用途十分广泛。而固体热载体法快速热解煤气为中热值煤气，可用作城市煤气、工业燃料，也可以用作化工原料。

煤炭破碎机是针对煤炭行业现状推出的一款新型专属设备，低耗是它的显著特点。黎明重工研发生产的煤炭破碎机属于无筛底粉碎机，干湿物料均可粉碎，因而粉碎范围非常广泛，比如煤炭、煤矸石、炉渣等多种物料。经由煤炭破碎机粉碎的成品粒度均匀，粒形更标准，级配合理，可以控制在2mm（毫米）以下。

我国露天煤矿开采技术水平已接近于国际较高水平，特别是一些大型的露天煤矿，如中煤集团平朔安太堡露天煤矿，采用新型的半连续开采工艺：单斗电铲采掘—移动破碎站—胶带运输系统。这种工艺适应性强、优点突出，已成为露天煤矿开采工艺的一个重要技术发展方向。

褐煤首先其水分很高，一般到厂的原料水分都高达30%左右。其次褐煤的挥发分很高，高达40%以上，燃点低，易于燃烧，故在粉磨工序中我们必须特别注意系统的温度控制。再次，褐煤的热值非常低，综合以上因素，我们推举立式磨粉机用于粉磨褐煤。

常用加工设备：中速磨煤机，欧版磨粉机


 黎明重工经过多年研究和试验，研发出专门针对清洁煤粉制备的相关装备及工艺，适用于无烟煤、烟煤和褐煤，煤粉细度调节准确，运行稳定，低耗能高产出，防爆性能可靠，赢得了客户的大量回头订单和广泛赞誉。

我们可以提供清洁煤粉制备生产线设备总包、交钥匙工程总包（EPC）等服务，包含：工程项目的设计、设备采购与制造、施工、试运行服务等工作。

高炉喷吹煤粉系统在电力、钢铁、冶金行业有着非常广泛的用途。在整个系统中，粉煤的制备是重要的环节，原煤经加工形成的煤粉质量决定着整套系统的运行效率。因为煤粉要求高，产量大，传统磨煤机无法满足其要求。于是，越来越多的客户将目光转向了新型磨煤机。

MTW系列欧版磨升级加强版经三十余年技术沉淀，吸收欧洲粉磨理念，厚积薄发，实现了工业磨粉机的技术革命，拥有多项自主专利技术产权，投放市场以来，通过多项科技成果鉴定，成为传统雷蒙磨、摆式磨以及球磨机更新换代产品，大型矿物规模化建厂必选装备。



    1、褐煤超细磨机是一种技能的设备，在同样的功耗环境下，比其他磨粉机产量提高一倍；

    2、采用高强度耐磨材质的磨辊磨环，大大提高了设备的使用寿命；

    3、设备内部无外置螺栓，取消滚动轴承外露设计，保障设备安全可靠运行；

    4、脉冲除尘设备让整套磨机系统更加环保，消除噪音污染。
