振動篩：是利用(yong)激(ji)振所產生的往復旋型振動而工作(zuo)的。振子的上(shang)旋轉重錘使(shi)產生(sheng)平面回(hui)旋(xuan)(xuan)振(zhen)動，而下旋(xuan)(xuan)轉(zhuan)(zhuan)重(zhong)錘則(ze)使篩面產生(sheng)錐面回(hui)轉(zhuan)(zhuan)振(zhen)動，其聯(lian)合作(zuo)用(yong)的效果則(ze)使篩面產生(sheng)復旋(xuan)(xuan)型振(zhen)動。其振(zhen)動軌跡是一復雜(za)的空間曲線。該曲線在(zai)水平面投影為(wei)一圓形，而在(zai)垂直面上(shang)的投影為(wei)一橢圓形。調節上(shang)、下旋(xuan)(xuan)轉(zhuan)(zhuan)重(zhong)錘的，可(ke)以改變。而調節上、下重(zhong)錘的空間，則可以改變篩(shai)面(mian)運(yun)(yun)動(dong)軌(gui)(gui)跡的曲線形狀并改變篩(shai)面(mian)上物料的運(yun)(yun)動(dong)軌(gui)(gui)跡。
簡介：是用于泥漿固相處理的(de)(de)一種(zhong)過濾(lv)性(xing)的(de)(de)機械分(fen)離設備，篩(shai)(shai)(shai)(shai)網(wang)(wang)和振子組(zu)成。篩(shai)(shai)(shai)(shai)網(wang)(wang)的(de)(de)粗細(xi)(xi)以(yi)目(mu)表(biao)示，一般50目(mu)以(yi)下(xia)(xia)的(de)(de)為(wei)粗篩(shai)(shai)(shai)(shai)網(wang)(wang)，80目(mu)以(yi)上(shang)的(de)(de)為(wei)細(xi)(xi)篩(shai)(shai)(shai)(shai)網(wang)(wang)。振子是一個(ge)偏心輪，在(zai)電動機帶動下(xia)(xia)旋(xuan)轉，使篩(shai)(shai)(shai)(shai)架發生振動。由于篩(shai)(shai)(shai)(shai)架的(de)(de)振動，泥漿流到篩(shai)(shai)(shai)(shai)面上(shang)時較(jiao)粗的(de)(de)固體(ti)顆粒就留在(zai)篩(shai)(shai)(shai)(shai)面上(shang)，并沿斜面從一端排出，較(jiao)細(xi)(xi)的(de)(de)固相顆粒和泥漿液體(ti)一起通(tong)過篩(shai)(shai)(shai)(shai)孔流到泥漿池去。
