Abstract

After the big earthquake, power shortage due to shut-down of the almost all of nuclear power plant is giving a serious damage to our pulp & paper industry. Again this summer, we have to survive in extreme environments. DIP is good for the ecology originally because using waste paper and not need much tree cutting. But now additionally it is required more direct contribution of reducing the electric power consumption as much as possible.<BR>So far, AIKAWA Iron Works has developed a lot of the most-advanced DIP facilities and lower power consumption systems under cooperation with users. For examples ; the combination system of HeliDisc high consistency pulper & Double Dumping Screen which has superior pulping action, coarse impurities removing and ink dispersion effects. Ultra low power consumption MaxFlow & GranFlow screens for coarse & fine stages. HyperCell which has all good points of past floatators. 4 shafts UV Breaker & ConiDisc hot dispersion system which required for high brightness.<BR>In this report, we would try to introduce additional equipment and systems as the countermeasures to this crisis. i.e. Continuance high consistency pulping system, Fractionating DIP system, applications of Flexible cascade cleaner system & HyperCell, Advanced MAXWave screen cylinder and Ultra low intensity post refining system.
