日产5000吨水泥熟料生产线（粉磨）工艺设计—参数2摘要本设计是针对5000t/d熟料新型干法生产线（粉磨）的工艺设计，水泥粉磨是水泥制造的最后工序，其主要功能在于将水泥熟料(及缓凝剂、性能调节材料等)粉磨至适宜的粒度(以细度、比表面积等表示)，形成一定的颗粒级配，增大其水化面积，加速水化速率，满足水泥浆体凝结，硬化要求。本次设计在配料计算基础上，进行了物料平衡、储库平衡、主机平衡计算，并以此为依据，对全厂储库、主机及辅机进行了选型和工艺布置；重点对水泥粉磨进行了工艺计算、设备规格设计、工艺布置设计。采用的是目前大多数大型水泥生产线水泥粉磨系统的优选方案之一，即带辊压机的挤压联合水泥粉磨系统，最大限度的降低能耗，设计熟料烧成能耗2950kJ/kg，减少基建投资，又最大限度的提高产量、质量，做到环保，技术经济指标先进、合理。关键词：水泥厂设计,水泥挤压联合粉磨，球磨机，辊压机5000T/DCEMENTCLINKERPRODUCTIONLINE(GRINDING)PROCESSDESIGN-TWOPARAMETERSABSTRACTThisdesignisaimattheendofkilntechnicsfor5000t/dripematerialnewtypedryprocesscalcinationsworkshop.Cementgrindingisattheendofthecementmanufactureprocess.Itsmainfunctionistocementclinkergrindingtosuitableparticle.Formcertainparticlegrading.Increaseitshydrationarea,acceleratethehydrationrate,andsatisfytheCementslurrycondensation,thehardeningrequirements.Thisdesigncarriedonthematerialbalance,reservoirbalanceandhostbalancecalculationwhichwerebasedonthecalculationoftheingredients,andasabasis,thewholeplantreservoir,mainandauxiliarymachineryhavingbeenselectedandcarriedonthelayoutprocess;andthenitwascarriedontheprocesscalculation,equipmentspecificationdesign,processlayoutdesignwhichwerefocusontheCementgrinding.Usingthemostcurrentlarge-scalecementproductionlinecementgrindingsystemoneofthepreferredoptions,witharollerpresstosqueezetheJointcementgrindingsystem,itcouldmaximumdecreasetheenergyconsumption,energyconsumptionforclinkerdesign2950kJ/kg,investmentofcapitalconstruction,inthesametime,italsomaximumenhancetheyieldandquality,satisfytherequirementofprotectingenvironmentandmakethetechnicaleconomicindexadvancedandreasonable.KEYWORDS:cementclinkerdesign,cementextrusionjointgrinding,ballmill，rollerpress目录前言.....................................................................................................1第1章工艺设计的指导思想与原则...............................................21.1总体设计...................................................................................21.1.1指导思想.........................................................................21.1.2设计原则.........................................................................21.1.3厂址选择........................................................................5第2章配料计算..............................................................................72.1毕业设计原始资料...................................................................72.2设计内容...................................................................................82.3配料计算...................................................................................82.3.1确定熟料的率值............................................................82.3.2熟料热耗的确定............................................................82.3.3计算煤灰掺入量............................................................82.3.4用EXCEL计算干生料的配合比..................................92.3.5将干料配比折算成湿料配比.......................................13第3章物料平衡............................................................................143.1烧成车间生产能力和工厂能力的计算..................................143.1.1窑型和规格的选取......................................................143.1.2窑的台时产量标定......................................................153.2原、燃材料消耗定额的计算................................................153.2.1生料消耗定额..............................................................153.2.2设计任务书要求..........................................................163.2.3干石膏消耗定额..........................................................173.2.4干混合材消耗定额......................................................173.2.5干煤的消耗定额量......................................................183.2.6设计水泥产量..............................................................18第4章主机平衡................................................................................194.1主机设备及工作制度.............................................................215章储库平衡....................................................................................245.1库的预计储期及储量.............................................................245.2生产工艺流程及特点.............................................................255.2.1工艺流程描述...............................................................255.2.2物料储存方式、储存量及储存期................................305.3水泥粉磨系统的比较和选择.................................................315.4工艺流程简介.........................................................................325.4.1熟料储存及输送...........................................................335.4.2水泥配料库及输送.......................................................335.4.3水泥粉磨.......................................................................335.4.4水泥储存及散装...........................................................335.4.5水泥包装及成品库.......................................................33第六章重点车间工艺计算..............................................................346.1磨机计算.................................................................................346.1.1磨机功率......................................................................346.1.2磨机产量.....................................................
