内蒙古科技大学毕业设计说明书毕各庄4.0Mt/a选矿厂设计摘要本设计任务为唐山毕各庄矿井型4.0Mt/a选煤厂,毕各庄是隶属于开滦集团的矿井型选煤厂。首先根据生产大样和浮沉试验资料的分析与综合,绘制可选性曲线;根据原煤的性质及精煤质量要求等,评定原煤为难选煤。在进行选煤方案比较的基础上,确定采用重介-浮选联合流程的选煤方法,并制定了工艺流程;然后经过工艺流程计算、设备选型,对主厂房和总平面进行布置,并进行了图纸的绘制。同时做出了该厂的经济技术分析,可知该设计实用性较高。关键字:难选煤;重介-浮选;设备选型;工艺布置BigeVillage4.0Mt/aconcentratordesignI内蒙古科技大学毕业设计说明书AbstractThisisaprocessdesignforthe4.0Mt/atypemineofcoalpreparationplantinBigeVillageofTangshan.BigeVillageattachestothemine-modelcoalpreparationplantofKailuaGroup.Firstofall,accordingtotheproductiondetailsandanalysisandsynthesisoffugitivedusttestdata,drawthewashabilitycurves,Washabilitycurvedrawing;Accordingtothenatureoftherawcoalandplantqualityrequirements,etc.,toevaluatetherawcoalincoal.Onthebasisofcoalpreparationschemecomparison,Determinethedensemedia-flotationcoalpreparationmethodofthejointprocess,Andformulatetheprocessflow;Andthenthroughtheprocesscalculation,equipmentselection,themainplantandtotalplanelayout,anddrawingthemap.Atthesametimemadetheplant'seconomictechnicalanalysis,practicalityishigher,thedesign.Keywords:difficultseparationcoal;Theheavy–flotation;Equipmentselection;ProcessarrangementII内蒙古科技大学毕业设计说明书目录摘要...............................................................IABSTRACT............................................................II第一章设计概要...................................................11.1项目背景......................................................11.2可行性研究概要................................................11.2.1原煤资料分析.............................................11.2.2选煤产品组成.............................................11.2.3选煤厂设计生产能力.......................................11.2.4选煤厂位置与交通.........................................11.2.5选煤方案的拟定...........................................11.2.6工艺流程.................................................11.2.7设备选择.................................................2第二章煤质资料的分析与综合.........................................32.1煤质资料的审查分析.............................................32.1.1煤质资料的审查............................................32.1.2煤质资料的分析............................................92.1.3筛分资料分析...............................................92.1.4浮沉资料分析...............................................92.1.5可选性分析.................................................9第三章选煤方法与工艺流程的制定.....................................123.1选煤方法和入选方式............................................123.2选煤方法的比较................................................123.2.1、跳汰分选指标计算........................................123.2.2重介(三产品)分选指标计算................................153.2.3理论与设计指标对比表......................................183.2.4工艺流程的确定............................................193.3工艺流程的简述及特点..........................................193.3.1工艺流程说明.............................................193.3.2工艺流程的特点...........................................20第四章工艺流程的计算......
