影響固體廢物篩分效率的因素-- 篩分設備的性能

       影響振動篩固體廢物篩分效率的因素-- 篩分設備的性能

a.振動篩篩網的類型，編織篩(shai)網的篩(shai)分效(xiao)率較(jiao)高，其次是沖(chong)孔篩(shai)，再次是棒條篩(shai);

b.振動(dong)篩(shai)(shai)篩(shai)(shai)孔(kong)(kong)的形(xing)(xing)(xing)狀，一般來講，方(fang)形(xing)(xing)(xing)篩(shai)(shai)孔(kong)(kong)比圓(yuan)形(xing)(xing)(xing)篩(shai)(shai)孔(kong)(kong)篩(shai)(shai)分(fen)(fen)效率高，但是篩(shai)(shai)分(fen)(fen)粒度較(jiao)小而水分(fen)(fen)較(jiao)高時，適(shi)宜采(cai)用(yong)圓(yuan)形(xing)(xing)(xing)篩(shai)(shai)孔(kong)(kong)，避免方(fang)形(xing)(xing)(xing)篩(shai)(shai)孔(kong)(kong)的四角附近發生顆(ke)粒粘連現象;

c.振(zhen)(zhen)動(dong)篩(shai)(shai)篩(shai)(shai)子的(de)運動(dong)方式，固定(ding)篩(shai)(shai)、轉(zhuan)筒篩(shai)(shai)、搖(yao)動(dong)篩(shai)(shai)、振(zhen)(zhen)動(dong)篩(shai)(shai)的(de)篩(shai)(shai)分效(xiao)率(lv)分別可(ke)以達到50%~60%、60%、70%~80%、90%以上;d.篩(shai)(shai)面大小(xiao)、形狀和傾(qing)角(jiao)，篩(shai)(shai)面大小(xiao)主要影響(xiang)篩(shai)(shai)子處理能力，通常(chang)篩(shai)(shai)面長寬比為(wei)(wei)2.53左右，篩(shai)(shai)面傾(qing)角(jiao)可(ke)以影響(xiang)篩(shai)(shai)分時間，從而影響(xiang)篩(shai)(shai)分效(xiao)率(lv)，通常(chang)篩(shai)(shai)面傾(qing)角(jiao)在15~25度為(wei)(wei)宜。
