1、日产 5000 吨水泥熟料水泥厂生料粉磨工艺设计 I 摘要摘要 本次设计的任务是日产 5000 吨水泥熟料水泥厂生料粉磨系统工艺设计。 近年来随着我国装备制造业技术水平和生产能力的不断提高， 水泥生产线的规模 大型化已渐成趋势。从国内外诸多水泥厂建设过程的经历来看，主机选型特别是 生料磨的选型合理与否是影响项目投资，工程进度和投产后经济效益的重要因 素。目前国内采用的生料磨系统主要有球磨烘干兼粉磨，立磨和辊压机终粉磨这 三种系统。粉磨效率低，能耗大是球磨机系统的缺点。辊压机系统在粒度级配， 操作维修等方面有缺陷。而立磨在粉磨和烘干能力，能耗及喂料粒度等方面性能 都很优越。所以立式磨属当代水泥工

2、业原料粉磨系统的首选。基于物料平衡计算 和设备选型计算，此次设计选择了产量为 400t/h的 MLS4531 立磨。 关键字：关键字：工艺设计 生料粉磨系统 立磨系统 物料平衡 设备选型 II ABSTRACT The design of the task is to produce 5,000 tons of cement clinker on cement raw material grinding system process design.As Chinas equipment manufacturing industry in recent years, technological

3、level and production capacity continues to improve, large scale cement production line technology has become the trend. The process of building a lot of cement from foreign experience point of view, the host selection in particular the selection of raw mill is reasonable or not is the impact of proj

4、ect investment, project progress and put into operation an important factor in economic. At present, raw mill system used in the main drying and grinding ball mill, vertical mill and roller press finish grinding these three systems. Grinding efficiency is low, energy consumption is the ball mill system shortcomings. Roller press system in the particle size, operation and maintenance and so flawed. Standing mill in grinding and drying capacity, energy consumption and feed particle size, etc. are
