Operating Experience of Hyper-Cell Floatator

Abstract

In Japan, the utilization rate of recovered paper reached 63% in 2009. Except paper board, ONP is mainly used for recovered paper. Since news paper quality, such as ash content, has been changed, ash and microsticky removal is required, especially at the flotation process for paper recycle. In order to improve DIP quality and promote further use of DIP, AIKAWA Iron Works Co., LTD and Nippon Paper Industries developed the state-of-the-art floatator “Hyper-Cell Floatator” and installed in Hokkaido Mill-Yufutsu in 2008. This report introduces our operating experience of Hyper-Cell Floatator.
