The Influence of Flow Characteristics in Deinking Cell on Fiber Loss

摘要：

The primary mechanism of fiber loss was physical entrainment.Flow characteristics within a flotation deinking cell affected water carry over and fiber entraining.The effects of pulp suspension flow and aeration flow on wet reject and fiber loss were studied in a laboratory flotation cell.The role of suspension jet impingement and aeration on flow turbulence,back mixing,froth production and rolling were discussed to explain wet reject and fiber loss under various flow conditions.
