  震動篩網是(shi)(shi)控制粉碎(sui)產品(pin)細度的主(zhu)要配件(jian)，也是(shi)(shi)錘片式(shi)粉碎(sui)機(ji)主(zhu)要的易損件(jian)之一。其種類、形狀、孔的密度、包角以及開(kai)孔率對粉碎(sui)和(he)篩分效果都有重要影(ying)響。一般在醫藥、食品(pin)、化工等領域適用比較多。

  震動篩(shai)網廠家對篩(shai)(shai)(shai)(shai)(shai)片(pian)的(de)開孔(kong)(kong)率(lv)與通過能(neng)(neng)力篩(shai)(shai)(shai)(shai)(shai)片(pian)的(de)開孔(kong)(kong)率(lv)是(shi)(shi)指篩(shai)(shai)(shai)(shai)(shai)片(pian)上(shang)篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)總(zong)面積占(zhan)整(zheng)個篩(shai)(shai)(shai)(shai)(shai)面面積的(de)百分比，篩(shai)(shai)(shai)(shai)(shai)片(pian)的(de)開孔(kong)(kong)率(lv)越高，粉(fen)碎機(ji)的(de)生產(chan)(chan)能(neng)(neng)力越大。開孔(kong)(kong)率(lv)的(de)增(zeng)大有兩條途徑：一(yi)(yi)是(shi)(shi)增(zeng)大篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)直徑，一(yi)(yi)是(shi)(shi)縮小篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)中心(xin)距。前(qian)者將(jiang)(jiang)使飼(si)料(liao)產(chan)(chan)品粒度增(zeng)大，均勻(yun)性降低(di)，后者將(jiang)(jiang)削弱(ruo)篩(shai)(shai)(shai)(shai)(shai)片(pian)的(de)強(qiang)度。實際(ji)生產(chan)(chan)中，篩(shai)(shai)(shai)(shai)(shai)孔(kong)(kong)直徑的(de)大小是(shi)(shi)由飼(si)喂對象決定(ding)的(de)，因此選擇篩(shai)(shai)(shai)(shai)(shai)片(pian)時(shi)，應符合產(chan)(chan)品的(de)粒度要(yao)求，根據(ju)篩(shai)(shai)(shai)(shai)(shai)片(pian)強(qiang)度再盡(jin)可能(neng)(neng)選用大孔(kong)(kong)徑篩(shai)(shai)(shai)(shai)(shai)片(pian)，以提高粉(fen)碎效(xiao)率(lv)、節約能(neng)(neng)耗。
