圓(yuan)振(zhen)動篩(shai)(shai)(shai)與(yu)復合振(zhen)動篩(shai)(shai)(shai)，可(ke)采(cai)用不(bu)銹鋼焊接篩(shai)(shai)(shai)板(ban)(ban)(ban)、沖孔(kong)篩(shai)(shai)(shai)板(ban)(ban)(ban)、聚氨(an)酯篩(shai)(shai)(shai)板(ban)(ban)(ban)和橡(xiang)膠篩(shai)(shai)(shai)板(ban)(ban)(ban)等。其緊固方(fang)式為中間用螺栓固定(ding)在梁上。當(dang)篩(shai)(shai)(shai)寬小于(yu)900 mm時，中間可(ke)不(bu)固定(ding)；篩(shai)(shai)(shai)寬超(chao)過2 100 mm時，中間應固定(ding)兩排螺栓，篩(shai)(shai)(shai)面兩側用張緊板(ban)(ban)(ban)壓(ya)緊。

直線(xian)振動(dong)篩(shai)(shai)(shai)的篩(shai)(shai)(shai)面(mian)，單(dan)層篩(shai)(shai)(shai)和雙層篩(shai)(shai)(shai)的下層，采用帶框(kuang)架的不(bu)銹(xiu)鋼篩(shai)(shai)(shai)面(mian)；雙層篩(shai)(shai)(shai)的上層篩(shai)(shai)(shai)面(mian)，當篩(shai)(shai)(shai)寬不(bu)超(chao)過(guo)(guo)1.5 m時(shi)采用自承重篩(shai)(shai)(shai)板，超(chao)過(guo)(guo)1.5 m時(shi)采用沖(chong)孔篩(shai)(shai)(shai)板或編織篩(shai)(shai)(shai)網等。其(qi)緊固方(fang)式是沿(yan)篩(shai)(shai)(shai)面(mian)兩側板處采用壓(ya)(ya)木、木楔壓(ya)(ya)緊。中間各塊篩(shai)(shai)(shai)板之間則用螺栓經(jing)壓(ya)(ya)板壓(ya)(ya)緊。

篩框所(suo)用橫梁(liang)(liang)一般(ban)用兩端帶法蘭的(de)封閉(bi)型(xing)材(cai)構成。目前多為(wei)圓形(xing)和矩形(xing)。當無合(he)適的(de)規(gui)格選(xuan)用時，矩形(xing)梁(liang)(liang)亦可壓制(zhi)對焊，其成型(xing)方式冷熱(re)均可，但在長度方向(xiang)同一形(xing)態只能一次(ci)成型(xing)。焊接應焊透，并(bing)進行退火(huo)處理．對直線振(zhen)動篩焊縫位置宜(yi)布置在振(zhen)動方向(xiang)的(de)垂線上(shang)。

篩框側板和后(hou)擋(dang)板、排料嘴及橫梁宜(yi)采用高強度螺(luo)栓或環槽鉚(liu)釘連(lian)接，受(shou)力較小部位也可采用普通螺(luo)栓加緊螺(luo)母連(lian)接。
