篩片廠家對篩(shai)(shai)(shai)片(pian)的(de)(de)(de)開(kai)孔(kong)(kong)(kong)(kong)率與通過能力(li)(li)篩(shai)(shai)(shai)片(pian)的(de)(de)(de)開(kai)孔(kong)(kong)(kong)(kong)率是(shi)(shi)指篩(shai)(shai)(shai)片(pian)上篩(shai)(shai)(shai)孔(kong)(kong)(kong)(kong)總面(mian)積占(zhan)整(zheng)個篩(shai)(shai)(shai)面(mian)面(mian)積的(de)(de)(de)百分比,篩(shai)(shai)(shai)片(pian)的(de)(de)(de)開(kai)孔(kong)(kong)(kong)(kong)率越(yue)(yue)高,粉(fen)碎機的(de)(de)(de)生(sheng)產(chan)能力(li)(li)越(yue)(yue)大(da)(da)(da)(da)。開(kai)孔(kong)(kong)(kong)(kong)率的(de)(de)(de)增大(da)(da)(da)(da)有兩條(tiao)途徑(jing):一是(shi)(shi)增大(da)(da)(da)(da)篩(shai)(shai)(shai)孔(kong)(kong)(kong)(kong)直徑(jing),一是(shi)(shi)縮小篩(shai)(shai)(shai)孔(kong)(kong)(kong)(kong)中(zhong)心距。前者(zhe)將(jiang)(jiang)使飼料(liao)產(chan)品(pin)粒度增大(da)(da)(da)(da),均勻(yun)性(xing)降低,后(hou)者(zhe)將(jiang)(jiang)削弱篩(shai)(shai)(shai)片(pian)的(de)(de)(de)強度。實(shi)際生(sheng)產(chan)中(zhong),篩(shai)(shai)(shai)孔(kong)(kong)(kong)(kong)直徑(jing)的(de)(de)(de)大(da)(da)(da)(da)小是(shi)(shi)由(you)飼喂對象決定(ding)的(de)(de)(de),因此選擇篩(shai)(shai)(shai)片(pian)時,應符合產(chan)品(pin)的(de)(de)(de)粒度要求,根(gen)據篩(shai)(shai)(shai)片(pian)強度再(zai)盡可能選用大(da)(da)(da)(da)孔(kong)(kong)(kong)(kong)徑(jing)篩(shai)(shai)(shai)片(pian),以提高粉(fen)碎效率、節(jie)約能耗。
