振動(dong)篩(shai)：是利用(yong)激振(zhen)所產(chan)生的(de)往復旋(xuan)型振(zhen)動(dong)而(er)工作的(de)。振(zhen)子的(de)上旋(xuan)轉重錘(chui)使產(chan)生平面回(hui)旋(xuan)振(zhen)動，而下(xia)旋(xuan)轉重(zhong)(zhong)錘則使篩面產(chan)生錐面回(hui)轉振(zhen)動，其聯合(he)作用的效果(guo)則使篩面產(chan)生復旋(xuan)型振(zhen)動。其振(zhen)動軌跡是一復雜的空間曲線(xian)。該曲線(xian)在水(shui)平面投(tou)影為一圓(yuan)形，而在垂直面上的投(tou)影為一橢圓(yuan)形。調節上、下(xia)旋(xuan)轉重(zhong)(zhong)錘的，可(ke)以(yi)改變。而(er)調節上、下重錘的空間，則可以改變(bian)篩(shai)面運動軌(gui)跡(ji)的曲線(xian)形(xing)狀并(bing)改變(bian)篩(shai)面上(shang)物料的運動軌(gui)跡(ji)。
簡介：是(shi)用于泥(ni)漿(jiang)固相處理的(de)一種(zhong)過濾性的(de)機械分離設(she)備，篩(shai)(shai)(shai)(shai)網(wang)和(he)振(zhen)子(zi)組(zu)成。篩(shai)(shai)(shai)(shai)網(wang)的(de)粗細以目表示，一般50目以下的(de)為粗篩(shai)(shai)(shai)(shai)網(wang)，80目以上的(de)為細篩(shai)(shai)(shai)(shai)網(wang)。振(zhen)子(zi)是(shi)一個偏心輪，在(zai)電動(dong)機帶動(dong)下旋轉，使篩(shai)(shai)(shai)(shai)架發生振(zhen)動(dong)。由于篩(shai)(shai)(shai)(shai)架的(de)振(zhen)動(dong)，泥(ni)漿(jiang)流(liu)到篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)上時較(jiao)粗的(de)固體顆粒就留在(zai)篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)上，并(bing)沿斜面(mian)(mian)(mian)從一端排出(chu)，較(jiao)細的(de)固相顆粒和(he)泥(ni)漿(jiang)液體一起通過篩(shai)(shai)(shai)(shai)孔流(liu)到泥(ni)漿(jiang)池去(qu)。
工作原(yuan)理：將顆(ke)(ke)粒(li)(li)(li)(li)大(da)小(xiao)(xiao)不(bu)同(tong)的碎散物(wu)料群,多次通過(guo)均勻布孔(kong)(kong)的單(dan)層(ceng)(ceng)或(huo)多層(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian),分(fen)成(cheng)(cheng)若干不(bu)同(tong)級別的過(guo)程成(cheng)(cheng)為(wei)(wei)篩(shai)(shai)(shai)(shai)(shai)分(fen)。大(da)于(yu)(yu)篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)的顆(ke)(ke)粒(li)(li)(li)(li)留在(zai)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)上(shang),稱(cheng)為(wei)(wei)該(gai)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)的篩(shai)(shai)(shai)(shai)(shai)上(shang)物(wu),小(xiao)(xiao)于(yu)(yu)篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)的顆(ke)(ke)粒(li)(li)(li)(li)透(tou)過(guo)篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong),稱(cheng)為(wei)(wei)該(gai)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)的篩(shai)(shai)(shai)(shai)(shai)下物(wu)。實(shi)(shi)際的篩(shai)(shai)(shai)(shai)(shai)分(fen)過(guo)程是(shi)：大(da)量粒(li)(li)(li)(li)度大(da)小(xiao)(xiao)不(bu)同(tong)、粗細(xi)(xi)混雜(za)的碎散物(wu)料進(jin)入篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)后(hou),只有一部分(fen)顆(ke)(ke)粒(li)(li)(li)(li)與(yu)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)接觸,由于(yu)(yu)篩(shai)(shai)(shai)(shai)(shai)箱的振(zhen)動,篩(shai)(shai)(shai)(shai)(shai)上(shang)物(wu)料層(ceng)(ceng)被松散,使大(da)顆(ke)(ke)粒(li)(li)(li)(li)本來就存在(zai)的間隙(xi)(xi)被進(jin)一步(bu)擴大(da),小(xiao)(xiao)顆(ke)(ke)粒(li)(li)(li)(li)乘機穿過(guo)間隙(xi)(xi),轉移(yi)到下層(ceng)(ceng)或(huo)運輸機上(shang)。由于(yu)(yu)小(xiao)(xiao)顆(ke)(ke)粒(li)(li)(li)(li)間隙(xi)(xi)小(xiao)(xiao),大(da)顆(ke)(ke)粒(li)(li)(li)(li)并不(bu)能穿過(guo)，于(yu)(yu)是(shi)原(yuan)來雜(za)亂無章排列的顆(ke)(ke)粒(li)(li)(li)(li)群發(fa)生(sheng)了(le)分(fen)離,即按顆(ke)(ke)粒(li)(li)(li)(li)大(da)小(xiao)(xiao)進(jin)行了(le)分(fen)層(ceng)(ceng),形成(cheng)(cheng)了(le)小(xiao)(xiao)顆(ke)(ke)粒(li)(li)(li)(li)在(zai)下,粗顆(ke)(ke)粒(li)(li)(li)(li)居上(shang)的排列規則。到達篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)的細(xi)(xi)顆(ke)(ke)粒(li)(li)(li)(li),小(xiao)(xiao)于(yu)(yu)篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)者透(tou)篩(shai)(shai)(shai)(shai)(shai),最(zui)終實(shi)(shi)現了(le)粗、細(xi)(xi)粒(li)(li)(li)(li)分(fen)離,完成(cheng)(cheng)篩(shai)(shai)(shai)(shai)(shai)分(fen)過(guo)程。然而，充(chong)分(fen)的分(fen)離是(shi)沒(mei)有的，在(zai)篩(shai)(shai)(shai)(shai)(shai)分(fen)時，一般都有一部分(fen)篩(shai)(shai)(shai)(shai)(shai)下物(wu)留在(zai)篩(shai)(shai)(shai)(shai)(shai)上(shang)物(wu)中。細(xi)(xi)粒(li)(li)(li)(li)透(tou)篩(shai)(shai)(shai)(shai)(shai)時，雖然顆(ke)(ke)粒(li)(li)(li)(li)都小(xiao)(xiao)于(yu)(yu)篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)，但它們透(tou)篩(shai)(shai)(shai)(shai)(shai)的難易程度不(bu)同(tong)，物(wu)料和篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)尺寸相近的顆(ke)(ke)粒(li)(li)(li)(li)，透(tou)篩(shai)(shai)(shai)(shai)(shai)就較難，透(tou)過(guo)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)下層(ceng)(ceng)的顆(ke)(ke)粒(li)(li)(li)(li)間隙(xi)(xi)就更難。
