洛阳理工学院毕业设计（论文）I立式辊磨机的选型和结构设计摘要立式辊磨机是利用料床粉碎原理进行粉磨物料的一种研磨机械。本课题是为了适应现代水泥工业的发展需求，满足水泥生产线所需要的粉磨能力而对MPS磨的开发研究，使之与日产3000吨的水泥工艺相适应。本次设计主要根据立式辊磨机的实际生产情况来确定设计的型号，进一步对立磨的主要结构进行设计和结构分析。力求简单、方便、耐用，保证磨机具有较高的粉磨效率,而且要能随时根据物料的磨蚀性对粉磨条件进行适时合理的控制与调整。在此基础上完成立磨主要结构零部件磨盘和磨辊等的设计以及主要受力部位的强度校核任务。本次设计既要保证磨内料床的形成,使物料有效地烘干和粉磨,又要保证有效地进行粉磨后的物料分级且输送合格的成品或半成品。使之满足水泥生产的要求。关键词：立式辊磨机，MPS磨，粉磨，强度校核洛阳理工学院毕业设计（论文）IISelectionofrollermillandstructuraldesignABSTRACTVerticalgrindingmillistheuseofbedisaprincipleofgrindingmaterials,grindingmachines.Itismainlyusedforcement,coalandelectricpowerindustries.Theissueistomeetthedevelopmentneedsofthemoderncementindustry，Cementproductionlinetomeettheneedsofthegrindingcapacityofgrindingonthere-developmentofMPS,Nissantomake3,000tonsofcementtechnologyfit.Thedesignofthemainverticalrollermillaccordingtotheactualproductiontodeterminethedesignofthemodel,andfurthergroundagainstthemajorstructuraldesignandstructuralanalysis.Thisdesignisnotonlyensuretheformationofbedmaterialwithinthemill,sothattheeffectivedryingandgrindingofmaterials,butalsotoensureeffectivelythematerialsaftergrindingandclassificationoffinishedorsemi-qualifiedtransportation.Tomakeitcontenttherequirementsofcementproduction.Basedonthemainstructurecomponentfinishgrindingmillwasdesignedandgrindingofthemainstresspositionandintensity.KEYWORDS:Verticalmill,MPSmill,Grinding,Intensity洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章立式辊磨机总体方案论证...................................................21.1立式粉磨机简述....................................................................21.1.1立磨工作系统工艺流程............................................................21.1.2立式磨机的结构及工作原理..............................................31.2立式粉磨机的工作原理与特点......................................51.2.1立式粉磨机的工作原理..............................................51.2.2立式粉磨机的特点......................................................61.3设计方案的提出及分析........................................................7第2章MPS3150立式磨机的主要参数............................................82.1MPS3150磨机主要参数.......................................................82.1.1MPS3150技术规格......................................................82.1.2钳角的确定...............................................................82.1.3磨辊直径与磨辊宽度的确定.......................................92.1.4磨机的规格................................................................102.1.5磨机的转速................................................................112.1.6磨盘上料层最佳厚度设计.........................................142.1.7磨辊的辊压................................................................142.1.8磨机的功率................................................................152.1.9磨机的产量...............................................................162.2MPS3150立式辊磨机身立柱...............................................162.2.1立磨机身立柱受力分析.............................................17第3章轴承的选择.......................................................................203.1轴承的计算及选择..............................................................203.1.1轴承选择....................................................................213.1.2轴承寿命的计算........................................................213.2轴承的当量动载荷..............................................................223.3轴承的选择..........................................................................23洛阳理工学院毕业设计（论文）IV3.4轴承的润滑和密封..............................................................243.4.1轴承的润滑................................................................243.4.2轴承的密封................................................................253.4.3轴承的公差等级........................................................25第4章MPS3150主要零部件的优化...........................................264.1易损件的选材优化..............................................................264.1.1辊轴的选材和校核....................................................264.1.2磨辊和磨盘材料的选择.............................................274.1.3磨盘衬板材料的选择................................................294.1.4磨盘材料的选择........................................................314.1.5液压缸、机身立柱材料的选择.................................314.2MPS3150立磨性能参数的核算...........................................314.2.1立磨的转速、生产能力的核算.................................314.2.2衬板寿命的核算........................................................334.2.3轴功率的计算............................................................334.2.4入磨物料允许最大尺寸的核算.................................344.3主要部分参数核算..............................................................34结论..............................................................................................36谢辞................................................................................................37参考文献..........................................................................................38附录..............................................................................................40外文资料翻译.....................................................................
