　　直線振動篩結構參數特點

　　(1)篩面長(chang)度與寬度

　　篩(shai)(shai)(shai)(shai)(shai)而(er)(er)(er)(er)寬度(du)(du)自接影響(xiang)生產率，而(er)(er)(er)(er)篩(shai)(shai)(shai)(shai)(shai)而(er)(er)(er)(er)長(chang)(chang)(chang)度(du)(du)接影響(xiang)篩(shai)(shai)(shai)(shai)(shai)分效(xiao)率。篩(shai)(shai)(shai)(shai)(shai)而(er)(er)(er)(er)長(chang)(chang)(chang)，物料在(zai)篩(shai)(shai)(shai)(shai)(shai)而(er)(er)(er)(er)上(shang)停留時(shi)間(jian)長(chang)(chang)(chang)，透篩(shai)(shai)(shai)(shai)(shai)機會多(duo), 所以篩(shai)(shai)(shai)(shai)(shai)分效(xiao)率高。實際(ji)上(shang), 篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)寬度(du)(du)對(dui)于篩(shai)(shai)(shai)(shai)(shai)分效(xiao)率, 篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)長(chang)(chang)(chang)度(du)(du)對(dui)于篩(shai)(shai)(shai)(shai)(shai)分能力(li)也都有不同程(cheng)度(du)(du)的影響(xiang)。一(yi)般寬長(chang)(chang)(chang)比為1:2~1:3 為宜(yi)。

　　(2)篩孔形狀與(yu)尺寸

　　篩孔(kong)形(xing)狀(zhuang)的選擇主要取決于對篩分產(chan)物粒度和對篩在較(jiao)下(xia)產(chan)品用途的要求。圓形(xing)篩孔(kong)與(yu)其(qi)他(ta)形(xing)狀(zhuang)的篩孔(kong)相(xiang)比，名義尺寸相(xiang)同(tong)的情況下(xia)，透過(guo)圓形(xing)篩孔(kong)的篩下(xia)物粗度較(jiao)小。
