大型直線振動篩是種大型篩分設備，寬1米，長兩米以上的直線振動篩設備都屬于大型直線振動篩。比如1020直線振動篩,1025直線振動篩，1030直線振動篩都屬于大型直線振動篩的一種。大型直線振動篩適合對產量要求大的客戶使用，該設備篩分效率高，篩分精度高，處理量大，大型直線振動篩的篩分過程概括來說是物料通過進料口均勻的進入直線篩，通過各不同(tong)層次篩網篩分多種規(gui)格的篩上物(wu)、篩下物(wu)，又(you)從不同(tong)的出(chu)料口排出(chu)，達到篩分目(mu)的。
大型直(zhi)線(xian)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)篩使(shi)用(yong)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)作為振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)源，采用(yong)雙振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)驅動(dong)(dong)(dong)(dong)(dong)，當(dang)兩臺振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)做(zuo)同(tong)(tong)步(bu)、反缶旋(xuan)轉時，振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)偏心塊所產生的(de)(de)(de)激振(zhen)(zhen)力(li)(li)(li)在(zai)(zai)平行于(yu)(yu)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)軸線(xian)的(de)(de)(de)方向(xiang)相互抵(di)消，在(zai)(zai)垂直(zhi)于(yu)(yu)振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)軸線(xian)的(de)(de)(de)方向(xiang)重(zhong)疊(die)為一(yi)(yi)合(he)力(li)(li)(li)，因此振(zhen)(zhen)動(dong)(dong)(dong)(dong)(dong)篩機(ji)(ji)的(de)(de)(de)運行軌(gui)跡為一(yi)(yi)直(zhi)線(xian)。兩電(dian)(dian)(dian)機(ji)(ji)軸相對篩面有(you)一(yi)(yi)傾角，在(zai)(zai)激振(zhen)(zhen)力(li)(li)(li)和(he)物料(liao)(liao)自重(zhong)力(li)(li)(li)的(de)(de)(de)合(he)力(li)(li)(li)下(xia)，物料(liao)(liao)在(zai)(zai)篩面上被拋(pao)起跳(tiao)躍式向(xiang)前做(zuo)直(zhi)線(xian)運動(dong)(dong)(dong)(dong)(dong)，通過各不(bu)同(tong)(tong)層次(ci)篩網篩分多種規格的(de)(de)(de)篩上物、篩下(xia)物，又(you)從不(bu)同(tong)(tong)的(de)(de)(de)出料(liao)(liao)口(kou)排出，流入料(liao)(liao)倉或盛(sheng)料(liao)(liao)筒，從而達到對物料(liao)(liao)進行篩分的(de)(de)(de)目的(de)(de)(de)。
