  滾筒篩篩分時間(jian)長短對(dui)篩分精度的(de)影響

  滾筒篩(shai)(shai)被篩(shai)(shai)分(fen)的(de)時間愈久，篩(shai)(shai)分(fen)精度(du)也(ye)愈高

  滾筒篩(shai)(shai)(shai)(shai)篩(shai)(shai)(shai)(shai)面(mian)(mian)的寬度(du)也必須適當，而且必須與篩(shai)(shai)(shai)(shai)面(mian)(mian)長(chang)度(du)保持一定比例關系。在(zai)(zai)篩(shai)(shai)(shai)(shai)子(zi)負荷相等時(shi)，篩(shai)(shai)(shai)(shai)子(zi)寬度(du)小(xiao)(xiao)而長(chang)度(du)很大，篩(shai)(shai)(shai)(shai)面(mian)(mian)上(shang)物(wu)料(liao)層厚，細粒難于接近篩(shai)(shai)(shai)(shai)面(mian)(mian)和(he)透過篩(shai)(shai)(shai)(shai)孔。相反，當篩(shai)(shai)(shai)(shai)面(mian)(mian)寬度(du)很大而長(chang)度(du)小(xiao)(xiao)時(shi)，物(wu)料(liao)層厚度(du)固然減小(xiao)(xiao)，細粒易于接近篩(shai)(shai)(shai)(shai)面(mian)(mian)，但(dan)由(you)于顆粒在(zai)(zai)篩(shai)(shai)(shai)(shai)面(mian)(mian)上(shang)停(ting)留時(shi)間短，物(wu)料(liao)通(tong)過篩(shai)(shai)(shai)(shai)孔的機會就少了(le)，篩(shai)(shai)(shai)(shai)分效率必然會降(jiang)低(di)。

  影響(xiang)直滾筒篩(shai)效率的(de)(de)因素有很(hen)多，除了振動(dong)電(dian)機功率的(de)(de)選型和振動(dong)電(dian)機偏心重錘的(de)(de)調節以及物料本身的(de)(de)特性(xing)等(deng)等(deng)，還有滾筒篩(shai)的(de)(de)長度和寬度對滾筒篩(shai)的(de)(de)篩(shai)分過程也有很(hen)大的(de)(de)影響(xiang)。

  篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)面愈長(chang)，物料(liao)在(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)上被(bei)(bei)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)的(de)(de)(de)時間(jian)愈久，篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)精(jing)度(du)(du)(du)也愈高(gao)。篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)時間(jian)(或篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)面長(chang)度(du)(du)(du))和篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效(xiao)率(lv)(lv)的(de)(de)(de)關系。初，稍微增(zeng)加(jia)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)時間(jian)，滾筒篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)是(shi)保(bao)證(zheng)沙廠工(gong)作(zuo)的(de)(de)(de)重要設備就有(you)許(xu)(xu)多(duo)(duo)“易篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)粒”大(da)量透過篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)孔，篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效(xiao)率(lv)(lv)很快增(zeng)加(jia)。后來(lai)，易篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)顆粒大(da)都被(bei)(bei)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)去了，剩下(xia)些難篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)顆粒，時間(jian)雖增(zeng)長(chang)，滾筒篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)被(bei)(bei)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)下(xia)的(de)(de)(de)并不(bu)(bu)多(duo)(duo)，篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效(xiao)率(lv)(lv)增(zeng)加(jia)也不(bu)(bu)大(da)。因此，篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)時間(jian)太長(chang)也是(shi)不(bu)(bu)合理的(de)(de)(de)。因為(wei)當篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)面傾角一定，要增(zeng)加(jia)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)時間(jian)，只有(you)增(zeng)加(jia)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)面長(chang)度(du)(du)(du)。篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)面太長(chang)并不(bu)(bu)好，浪費(fei)廠房空間(jian)，篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)子構(gou)造笨重，篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效(xiao)率(lv)(lv)提(ti)高(gao)不(bu)(bu)多(duo)(duo)，所以篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)子長(chang)度(du)(du)(du)必須適當。只有(you)在(zai)高(gao)負荷工(gong)作(zuo)的(de)(de)(de)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)子，為(wei)了保(bao)證(zheng)較高(gao)的(de)(de)(de)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)分(fen)(fen)(fen)效(xiao)率(lv)(lv)，如果配置條件(jian)許(xu)(xu)可，適當增(zeng)加(jia)篩(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)(shai)子長(chang)度(du)(du)(du)，有(you)時是(shi)有(you)利的(de)(de)(de)。
