篩分機篩面的長度和寬度:
篩(shai)(shai)(shai)面(mian)(mian)的(de)(de)(de)寬度決(jue)定(ding)篩(shai)(shai)(shai)分(fen)機(ji)(ji)的(de)(de)(de)處理能(neng)力(li),若(ruo)篩(shai)(shai)(shai)面(mian)(mian)寬物料的(de)(de)(de)通過(guo)(guo)能(neng)力(li)大;篩(shai)(shai)(shai)面(mian)(mian)的(de)(de)(de)長(chang)度決(jue)定(ding)篩(shai)(shai)(shai)分(fen)機(ji)(ji)的(de)(de)(de)篩(shai)(shai)(shai)分(fen)效(xiao)率(lv),篩(shai)(shai)(shai)面(mian)(mian)越長(chang)物料經過(guo)(guo)篩(shai)(shai)(shai)分(fen)的(de)(de)(de)時間越長(chang),篩(shai)(shai)(shai)分(fen)越徹底,但是,過(guo)(guo)長(chang)的(de)(de)(de)篩(shai)(shai)(shai)面(mian)(mian)對提高(gao)篩(shai)(shai)(shai)分(fen)效(xiao)率(lv)并不(bu)顯著(zhu),而僅僅多余地加長(chang)了篩(shai)(shai)(shai)分(fen)機(ji)(ji)的(de)(de)(de)尺(chi)寸。
我國現有篩分機其篩面長度,粗粒級(ji)的篩分3.5~4 m,中細粒級(ji)的篩分5.5~5.6 m,脫水、脫介6.5 m。
篩(shai)分機篩(shai)面的傾(qing)角:
篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)傾角(jiao)的(de)(de)大小,影響篩(shai)(shai)(shai)(shai)(shai)(shai)上(shang)物料的(de)(de)移(yi)動(dong)速度。傾角(jiao)大,物料的(de)(de)移(yi)動(dong)快,處理能力(li)高。篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)的(de)(de)傾角(jiao)和篩(shai)(shai)(shai)(shai)(shai)(shai)子的(de)(de)結(jie)構形式與篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)產品的(de)(de)質量要求有(you)關(guan)。一般篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)在50 mm以上(shang),作預(yu)先(xian)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)時,都采用圓(yuan)運(yun)(yun)動(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)機(ji),如慣性振(zhen)動(dong)篩(shai)(shai)(shai)(shai)(shai)(shai)和自定中心振(zhen)動(dong)篩(shai)(shai)(shai)(shai)(shai)(shai),其傾角(jiao)為15°~20°。而直線運(yun)(yun)動(dong)的(de)(de)篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)機(ji),一般作水(shui)平安裝(zhuang),其傾角(jiao)為零(ling)度,物料在篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)上(shang)運(yun)(yun)動(dong),依靠(kao)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)對物料的(de)(de)拋(pao)射力(li),這種篩(shai)(shai)(shai)(shai)(shai)(shai)分(fen)機(ji)一般用于煤的(de)(de)脫水(shui)、脫泥和脫介。
