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。

新型干法水泥技术代表了现阶段最高的水泥烧成技术,可以提高窑单位容积产量、提高窑砖衬寿命和运转率,且自动化水平高、生产规模大,可以选用低质燃料或低价废物燃料,节省燃料,降低热耗和电耗,减小设备和基建投资费用、CO 和 NOx生成量少和事故率低,操作稳定。
日产5000吨水泥熟料的水泥厂生料磨工艺系统的设计前言一、生料粉磨作业的功能和意义生料粉磨是水泥生产地重要工序,其主要功能在于为熟料煅烧提供性能优良的粉状生料。
对粉磨生料要求:一是要达到规定的颗粒大小;二是不同化学成分的原料混合均匀;三是粉磨效率高、能耗少、工艺简单、易于大型化、形成规模化得生产能力。
由于生料粉磨设备、土建等建设投资高,消耗能量大(一般占水泥综合电耗的1/4以上),因此采用高新技术,优化生料粉磨工艺,对水泥工业现代化建设有着十分重要的作用和意义。
二、粉磨的基本原理物料的粉磨是在外力作用下,通过冲击、挤压、研磨克服物料晶体内部各质点及警惕之间的内聚力,使大块物料变成小块以至细粉的过程。
粉磨功一部分用于物料生成新的表面,变成固体的自由表面能;大部分则转变为热量散失于空间中。
三、现代生料粉磨技术发展的特点随着新型干法水泥技术日趋完善,生料粉磨工艺取得了重大进展,其发展历程经历两大阶段:第一阶段,20世纪50年代至70年代,烘干兼粉碎钢球磨机发展阶段(包括:风扫磨及尾卸、中卸提升循环磨);第二阶段,20世纪70年代至今,辊式磨及辊压机发展阶段。
其发展特点如下:(1)原料的烘干和粉磨作业一体化,烘干兼粉磨系统得到了广泛的应用。
并且由于结构及材质方面的改进,辊式磨获得新的发展。
(2)磨机与新型高效的选分、输送设备相匹配,组成各种新型干法闭路粉磨系统,以提高粉磨效率,增加粉磨功的有效利用率。
(3)设备日趋大型化,以简化设备和工艺流程,同窑的大型化相匹配。
钢球磨机直径已达5.5m以上,电功率6500kw台时产量300t以上,辊式磨系列中磨盘直径已达5m以上电机功率5000kw以上,台时产量500吨以上。
(4)采用电子计量称喂料、X荧光分析仪或γ-射线分析仪、电子计算机自动调节系统,控制原料配料,为入窑生料成分均齐稳定创造条件。
本科生毕业设计(5)磨机系统操作自动化,应用自动调节回路及电子计算机控制生产,带他人工操作,力求生产稳定。
摘要本设计的设计题目是日产5000吨水泥熟料水泥厂新型干法生产线烧成系统工艺设计。

浙江工业大学教科学院毕业设计外文资料翻译设计题目:日产5000吨新型干法水泥生产线生料车间工艺设计学生姓名:学号:200621600111专业:建筑材料与工程外文出处:《中国水泥》2003年第9期指导教师:李振明2009年2月25 日Thoughts on the Current Cement Industry Development According to the analysis of cement capacity and its relations with macro economy running index, the main reasons for the present rapid development of cement capacity the rapid development of economy and the shot up of whole society fixed asset investment.According to the present speed of economy development, cement still enjoys a potential increased, So here has not been all overall excessive popularity of cement industry.The best way to prevent low level repeated construction is top remote the development of new dry—process cement as well as try to get rid of blindness.During the ninth “five—year plan” period,Chinese cement output increased from 475.61 million ton of the year 1995 to 597 million of the year 2000,with a average yearly increase of 25 million ton and a yearly increase rate 4.5%.During the tenth“ five—year plan” period, the government keeps adopting the policy of promoting domestic demand,the national economy keeps a constant rapid healthy development and cement output increases rapidly. In 2001,the whole country’s cement output reached 661.04 million ton with an increase rate of 10.7% compared to that of the year 2000.In 2002,it reached to 0.725 billion ton with a net increase volume of 64 million ton and an increase rate of 9.2% compared to that of the year 2001.From January to July of this year,cement production keeps a strong increase trend and increased 15.6% compared with the same time last year.Is cement industry at a normal increase speed? Is cement industry development over popular? These have become the focus for all aspects.1. Market demand is the sole criterion of the reasonable increase speed of cement capacityThe nature of cement decides its usual duration of three months. As a result, cement consumption and its output have a good accordance with little import.In recent years,the production—sales rate of cement keeps around 94%一97%.As an investment production, cement has a main consumption market in industry, construction industry,housing,roads building,basic establishment construction and some building materials such as cement products.The criterion to decide whether cement industry development is over popular is to see whether the development of its capacity meets its consumption or in other words,meets its market demand.Historical data shows that the increase speed and structure of GDP and whole society fixed asset investment and the living conditions of people decide the development speed of many industries such as construction industry and real estate industry. The changes of cement consumption have close relations with the changes of these factors.1.1 Cement consumption volume and GDP increaseIn recent years,the development of Chinese national economy has come into a rapid increase period and GDP enjoys an obvious speed up development.During this period,Chinese cement consumption enjoys a cycle fluctuation accordingly.Cement consumption increases and decreases by a certain margin with the rapid increase and decrease of GDP.but with an obvious delay.However,when GDP changes steadily with an increase a rate of about 10%,the changes of cement consumption do not have obvious relations with the changes of the increase rate of GDP. The changes of cement consumption are related not only to the increase of GDP but also to the structure of economy development.1.2 Cement consumption volume and the increase of fixed asset investment From the ninth“ five—year p1an",Chinese who1e society fixed asset investment has increased rapidly.During the ninth“ five—year plan” period,fixed asset investment enjoyed a yearly increase rate of10.46%.After the entry to the tenth“ five—year plan” period, it has an average increase rate of 14.56%.The yearly gross investment volume was 2780 billion Yuan during the ninth“ five—year plan” period whileit reached to 4020 billion Yuan in the year 2002 with a yearly increase volume of 1240 billon Yuan and an increase rate of 24.6%.Data show that the increase of cement consumption results mainly from the drive from fixed asset investment.The increase of cement consumption an d that of fixed asset investment have close relations. That is,cement consumption has a definite increase according to the increase of fixed asset investment and the increase margin is regulated by market.1.3 Cement consumption volume and the development speed of secondary industryAfter the analysis of the structure of fixed asset investment,we can find that secondary industry (including industry,construction industry,cement products and so on)is the main content of fixed asset investment and main force of cement consumption.The increase volume of cement consumption obviously changes with the changes of secondary industry increase speed,which fully indicates secondary industry’s promotion on gross cement consumption.1.4 Construction industry investment and gross cement consumption volume Construction industry is the main market for cement consumption. Gross cement consumption volume increases together with the increase of gross construction industry product, or the increase of construction industry investment.1.5 The relations between real estate industry investment and gross cement consumptionReal estate industry is a new industry that has risen suddenly in recent years and appears a powerful development trend. In the first two years of the tenth“five- year plan”period,the average increase rate of real estate investment reached 24.6%.The real estate investment nearly four timed that of the ninth“ five—year plan” period and increased by6.4%.In the year 2002.real estate investment reached 773.6 billion Yuan.which increased by 84.2% compared to the yearly investment of 382billion Yuan in the ninth“ five—year plan” period. The real estate industry investment has strongly driven the increase of gross cement consumption volume.The data indicate that real estate investment and cement consumption increase volume are closely linked to each other. In recent years, the increase of real estate investment has been one of the main drives of the increase of gross cement consumption volume.1.6 As a investment product, cement especially is closely linked to the income of citizens in a well-of society.Cement consumption index is closely linked to the citizen income increase.Especially, the index changes with the changes of citizen consume structure.That is,the larger the housing investment proportion of the citizen income,the more citizen income index impacts cement consumption.The relations between the increases of gross cement consumption volume and of citizen income index reflect a good market allocation of cement resources.The data in the above figure and tables indicate as follows:(1)What mainly impact the gross cement consumption volume is the development speed of whole society fixed asset investment, construction industry investment and gross real estate industry investment volume,which is the comprehensive reflection of market allocation of cement resources.In recent years,the rapid development of cement productivity is the natural result of rapid increase of whole society fixed asset investment volume,especially the result great increase of basic establishment, secondary industry, construction industry and real estate industry.(2)The increase of gross cement consumption volume has close relations with people, especially citizen income index increase. The increase of citizen income drives the gross consumption of cement.(3)According to the analysis of the change regulation of investment,consumption and gross cement consumption in the latest twelve years economy development, the temporary cement capacity development speed keeps a coordinate relationship with this co untry’s economy development spe ed an d gross market demand for cement. Especially,there has not been any non—coordination in its relations with fixed asset investment,construction industry,real estate investment increase margin and the development speed of secondary industry.The increase speed of cement production is norma1. It is normal that in a short period there can be a small fluctuation between cement capacity and price. This is the reflection of market allocation of resources and its final result is to adjust cement capacity and price better to the requirement of market.思考当前水泥工业发展据分析,水泥能力以及它与宏观经济运行指数,主要原因是目前快速发展的水泥能力的迅速发展,经济和上升的全社会固定资产投资。
