篩(shai)分設備的技術經濟指標(biao)是(shi)篩(shai)分效(xiao)率(lv)和生產率(lv)。前者(zhe)為質量(liang)指標(biao)，后(hou)者(zhe)為數量(liang)指標(biao)。它們之(zhi)間有一定的關(guan)系，同時還與其(qi)他(ta)許多因素有關(guan)，這些因素決定篩(shai)分的結果。

影響振動篩分設備篩分過程的因素大體可以分三類：

振動篩的(de)工(gong)作原理是粒(li)子(zi)和(he)篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)作垂直運動(dong)，所以篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)高(gao)，生(sheng)產(chan)(chan)(chan)能力(li)大。而粒(li)子(zi)與(yu)篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)相對運動(dong)主要是平(ping)行運動(dong)的(de)棒條篩(shai)(shai)(shai)(shai)、平(ping)面(mian)(mian)(mian)(mian)振動(dong)篩(shai)(shai)(shai)(shai)、筒篩(shai)(shai)(shai)(shai)等，其篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)和(he)生(sheng)產(chan)(chan)(chan)能力(li)都低(di)。 對于一定的(de)物料而言，篩(shai)(shai)(shai)(shai)子(zi)的(de)生(sheng)產(chan)(chan)(chan)率(lv)(lv)和(he)篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)決定于篩(shai)(shai)(shai)(shai)孔尺(chi)寸。生(sheng)產(chan)(chan)(chan)率(lv)(lv)取(qu)決于篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)寬度(du)，篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)寬生(sheng)產(chan)(chan)(chan)率(lv)(lv)高(gao)。篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)取(qu)決于篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)長(chang)度(du)，篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)長(chang)篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)高(gao)。一般長(chang)寬比(bi)為2。 有(you)效(xiao)的(de)篩(shai)(shai)(shai)(shai)子(zi)面(mian)(mian)(mian)(mian)積(ji)(ji)（即篩(shai)(shai)(shai)(shai)孔面(mian)(mian)(mian)(mian)積(ji)(ji)與(yu)整個篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)面(mian)(mian)(mian)(mian)積(ji)(ji)之(zhi)比(bi)）愈大，則篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)的(de)單位(wei)面(mian)(mian)(mian)(mian)積(ji)(ji)生(sheng)產(chan)(chan)(chan)率(lv)(lv)和(he)篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)愈高(gao)。 篩(shai)(shai)(shai)(shai)孔尺(chi)寸愈大，則單位(wei)篩(shai)(shai)(shai)(shai)面(mian)(mian)(mian)(mian)的(de)生(sheng)產(chan)(chan)(chan)率(lv)(lv)越大，篩(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)(lv)越高(gao)。

當振(zhen)動(dong)篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)設(she)(she)備篩(shai)(shai)(shai)(shai)子(zi)的負荷較大時，篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)效率(lv)低(di)。在很大程(cheng)度上篩(shai)(shai)(shai)(shai)子(zi)的和(he)平率(lv)取(qu)決于篩(shai)(shai)(shai)(shai)孔大小(xiao)和(he)總篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)效率(lv)；篩(shai)(shai)(shai)(shai)孔愈(yu)大，要求篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)效率(lv)愈(yu)低(di)時，則生產率(lv)愈(yu)高。 振(zhen)動(dong)篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)設(she)(she)備給料(liao)均勻性(xing)對篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)過程(cheng)意義很大。 振(zhen)動(dong)篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)設(she)(she)備傾角要適宜，一(yi)般通過試驗來確定。再就是篩(shai)(shai)(shai)(shai)子(zi)的振(zhen)幅與(yu)振(zhen)次，這與(yu)篩(shai)(shai)(shai)(shai)子(zi)的結構物性(xing)有(you)關，在一(yi)定的范(fan)圍內(nei)，增(zeng)加振(zhen)動(dong)可(ke)以提高篩(shai)(shai)(shai)(shai)分(fen)(fen)(fen)(fen)指(zhi)標。

包括物料(liao)本身的(de)(de)(de)粒度(du)組(zu)成、濕(shi)(shi)度(du)、含(han)泥(ni)量和粒子(zi)的(de)(de)(de)形狀等。 當(dang)(dang)物料(liao)細(xi)粒含(han)量較大(da)(da)時(shi)，篩(shai)(shai)(shai)子(zi)的(de)(de)(de)生產率(lv)也大(da)(da)。當(dang)(dang)物料(liao)的(de)(de)(de)濕(shi)(shi)度(du)較大(da)(da)時(shi)，一(yi)般來說篩(shai)(shai)(shai)分效率(lv)都會降低。但篩(shai)(shai)(shai)孔尺寸(cun)愈大(da)(da)，水(shui)分影(ying)響愈小，所以(yi)(yi)對于含(han)水(shui)分較大(da)(da)的(de)(de)(de)濕(shi)(shi)物料(liao)， 為了改善篩(shai)(shai)(shai)分過程(cheng)，一(yi)般可以(yi)(yi)采(cai)(cai)用(yong)加大(da)(da)篩(shai)(shai)(shai)孔的(de)(de)(de)辦(ban)法(fa)，或者采(cai)(cai)用(yong)濕(shi)(shi)式篩(shai)(shai)(shai)分。物料(liao)含(han)泥(ni)量大(da)(da)（當(dang)(dang)含(han)泥(ni)量大(da)(da)于8%時(shi)）應當(dang)(dang)采(cai)(cai)用(yong)濕(shi)(shi)式篩(shai)(shai)(shai)分，或預先(xian)洗礦。
