外旋翼內流壓力篩是一種目前運于篩選纖維種類最廣范，篩選最穩定高效的一種壓力式篩選設備。是用于造紙制漿系統的精篩和紙機前的低濃度網前篩選。它利用離心力的影響，使雜質不易磨損篩板。更適合0.15--0.25的細縫篩鼓，動力省，單產能耗節省60--80%，篩渣量小，出漿壓力平穩，脈動低。

External rotor internal flow pressure screen is one of the most stable and efficient pressure screening equipment, which is currently used to screen the most wide range of fibers. It is used for fine screening of papermaking pulping system and screening of low concentration screen before paper machine. It uses the influence of centrifugal force to make the impurities not easy to wear the sieve plate. It is more suitable for 0.15-0.25 slit sieve drum with low power consumption, 60-80% energy saving per unit yield, small sieve slag volume, stable pulping pressure and low pulsation.
