Shakingtableinstruction一、概況:搖床是用于選別細(xì)粒物料的重力選礦設(shè)備,它廣泛應(yīng)用于選別鎢、錫、鉭、鈮和其它稀有金屬和貴金屬礦石,也可用于選別鐵、錳礦石和煤。當(dāng)處理鎢、錫礦石時,搖床的有效回收粒度范圍為2~0.04毫米。搖床的選礦過程是在具有來復(fù)條的傾斜床面上進(jìn)行的(如圖。砂粒群從搖床面上角的給礦槽(砂槽送入,同時由給水槽供給橫向沖洗水。于是,礦粒在重力、橫向水流沖力,床面作往復(fù)不對稱運(yùn)動所產(chǎn)生的慣性力和摩擦力的作用下,按比重和粒度分層,并沿床面作縱向運(yùn)動和沿傾斜床面作橫向運(yùn)動。因此,比重及粒度不同的礦粒沿著各自的運(yùn)動方向逐漸由A邊向B邊呈扇形流下,分別從精礦端和尾礦側(cè)的不同區(qū)排出,最后被分成精礦、中礦和尾礦。由下圖可看出床面礦流的運(yùn)動方向。一DescriptionThetableisagravityseparationequipmenttochoosefinematerials,itiswidelyusedinselectionoftungsten,tin,niobiumandotherraremetalsandpreciousmetalore,itcanalsobeusedforclassifyingiron,manganeseoreandcoal.Whendealingwithtungsten,tinore,thetable’seffectiverecyclingscopeis2~0.04mm..Dressingtableisinaninclinedbedonthestripsurface.Sandgroupisgivenfromthetablesurfaceangleofthefeeder,Atthesametimetosinkbylateralflushingwatersupply,So,mineralparticlesareundertheactionofgravity,lateralimpulsiveforce,inertialforceandfrictionbedreciprocatingasymmetricmotionlayeredaccordingtotheproportion.Andalongthebedsurfacedolongitudinalmotionandtransversemotion.therefore,DifferentdensityandsizeofparticlesalongtheirrespectivedirectionofmotionflowgraduallyfromAsidetoBside.搖床工作示意圖根據(jù)選別的礦石粒度不同,搖床可分礦砂(2~0.2毫米搖床和礦泥(0.2~0.037毫米搖床。兩者的區(qū)別僅是床面上來復(fù)條的型式和選用的沖程、沖次不同,基本結(jié)構(gòu)是相同的,所以,同一結(jié)構(gòu)的搖床,只要更換不同型式的床面,就可以從礦砂搖床變?yōu)榈V泥搖床。((Accordingtothedifferentselectedoresize,shakingtablecanbedividedintosandtable(2~0.2mmandmudtable(0.2~0.037mm.Thedifferenceisonlyonselectionofthestroke,thebasicstructureisthesame,so,,aslongasreplacedifferenttypesofbedsurface,canmakethesandtablebecomemudtable二、搖床的構(gòu)造:主要由床面、傳動機(jī)構(gòu)(床頭和調(diào)坡機(jī)構(gòu)等組成(。Two,thetablestructure:mainlyconsistofthebed,drivemechanism(bedcompositionandgradientadjustmentmechanism.床面形狀有梯形和菱形兩種。床面一般為木制。木制床面上鋪有一層漆灰或橡皮(或采用聚氯脂耐磨橡膠作為耐磨層。有的選礦廠采用水泥床面,以節(jié)省木材。在水泥床面上可涂上生漆,選礦效果也很好。還有使用聚氯乙烯塑料床面。(Thebedsurfaceshapearetrapezoidanddiamond,Thebedsurfaceisgenerallymadeofwood.Thewoodenbedsurfacewithalayeroflacquerashorrubber,(Ortheuseofpolyvinylchloridegreaseresistantrubberaswear-resistinglayer.Someconcentratorsusingcementbed,inordertosavewood.Inthecementbedsurfacecanbecoatedwithlacquer,dressingeffectisalsoverygood.othersusePVCplasticbed.床面通常釘有木制的來復(fù)條或刻有溝槽。來復(fù)條的高度由給礦端向精礦端逐漸減小,以使分層后的礦粒逐漸被橫向水流沖下。(Thebedsurfaceisusuallynailedawoodenriflesorcarvedwithgrooves.Theheightofriflesaredecreasingfromfeedendtotheconcentrates,Inordertomakethestratifiedorebeinglaterallyunderwater來復(fù)條的形狀、尺寸和排列方法應(yīng)適應(yīng)給礦的要求。當(dāng)處理粗砂時,希望造成對分選有利的渦流,因此采用高度較大的來復(fù)條,當(dāng)處理細(xì)砂和礦泥時,希望礦泥流平穩(wěn),不產(chǎn)生強(qiáng)烈的旋渦,因此采用高度小的來復(fù)條或刻槽床面。以下為常用來復(fù)條的斷面形狀和排列方式。種類有:矩形(實用于礦砂搖床、三角形(實用于礦泥搖床,梯形(實用于礦砂搖床、鋸齒形(實用于礦泥搖床,刻槽形(實用于礦泥搖床。床面上端有給礦槽和給水槽。(Theshape,sizeandarrangementonthestripmethodshouldmeettherequirementsformine.Whendealingwithcoarsesand,hopetocontributetothefavorablevortexseparation,sochoosethehighreflex,whendealingwithfinesandandmud,hopeminemudflowsmooth,doesnotproducestrongvortex,sowechoosethesmallrifleorcavedbedsurface.Thefollowingisoftenusedtocomplexasectionshapeandarrangement.Typesare:rectangular(applicabletosandtable,triangle(applicabletomudtable,trapezoidal(applicabletosandtable,zigzag(applicabletomudtable,grooveshape(applicabletomudtable.Thebedsurfaceisprovidedwithafeedchuteandfeedwatertank.云錫式搖床是采用凸輪杠桿式傳動機(jī)構(gòu)(如下圖,床面下設(shè)彈簧裝置,彈簧座固定在地基上。床面的后退運(yùn)動依靠搖動機(jī)構(gòu),前進(jìn)運(yùn)動依靠彈簧裝置,床面支承采用滑動支承。床面坡度采用楔形調(diào)坡機(jī)構(gòu)調(diào)節(jié)。(Yunxitypetableisusingcamleverdrivemechanism(below,underthebedsurfacetheisspringdevice,springseatisfixedontheground.Thebedsurfacebackmovementdependsontherockingmechanism,forwardmovementdependsonthespringdevice,thebedsurfaceissupportedwithslidingbearing.Thebedsurfaceslopeisadjustedbywedgeslopeadjustingmechanism.凸輪杠桿式傳動機(jī)構(gòu)(Camandlevertypedrivingmechanism1拉桿;2調(diào)節(jié)絲桿;3滑動頭;4大皮帶輪;5偏心軸;6滾輪;7支臂偏心軸;8搖桿支臂;9連接桿;10搖桿臂;11搖臂軸;12箱體;13聯(lián)接叉(1.Pullrod2.adjustingscrewrod3slidinghead;4pulley5eccentricshaft6roller;;7armeccentricshaft;the8rockerarm;the9connectingrod;10rockerarm;11rockershaft;12box;13connectingfork三、搖床的主要參數(shù)(Themainparametersofthetable1.床面的形狀和尺寸:床面形狀有梯形和菱形兩種。工業(yè)用搖床主要采用梯形床面。工業(yè)用床面尺寸(長×寬一般為5400X1800毫米,長寬比為2.5(Theshapeandsizeofbedsurface:bedhastrapezoidanddiamondshapes.Industrialtablemainlyadoptsthetrapezoidalbed.Industrialbedsize(length*widthisgenerally5400X1800mm,lengthandwidthratiois2.5選別細(xì)泥時(-37微米占93%,其適宜的床面長寬比為2~2.5。(Choosefinemud(-37umoccupied93%,theappropriateratiois2~2.5.2.沖程與沖次:沖程與沖次是根據(jù)被選礦物的粒度來選擇的。粗粒礦物應(yīng)選用大沖程低沖次;細(xì)粒礦物選用小沖程高沖次。沖程調(diào)節(jié)范圍一般為8~25毫米,沖次調(diào)節(jié)范圍為250~400次/分。(Strokeandstroke:strokeandstrokefrequencyisselectedaccordingtothesizeoftheselectedmineral.Coarsegrainedmineralsshouldchooselargestrokelowstrokefrequency;offinemineralparticleswithsmallstrokehighstroke.Strokeadjustmentrangeisgenerally8~25mm,strokeadjustmentrangeis250to400beatsperminute.3.設(shè)計搖床的傳動機(jī)構(gòu)時,沖程與沖次必須是可以調(diào)節(jié)的。電動機(jī)功率:搖床的電能消耗不大,電動機(jī)容量可根據(jù)規(guī)格大小和生產(chǎn)能力取0.55~1千瓦。(whendesignthetran
