Description

In the pulp refining process, generally double disk refiners (DDR) are installed. Pulp refining needs much energy, so that to develop energy saving technology of pulp refining is one of the most important objectives. However, energy saving technologies of pulp refining sometimes causes pulp strength declining, so that the balance between energy saving and pulp strength is very important.<BR>Recently, the new model of refining plates “FineBar (Aikawa Iron Works Co., Ltd.) ”, which is made by stainless steel and has1mm-width blade, was installed into our DDR for bleached hardwood kraft pulp. This installation results power consunpution is decresed even though pulp strength is maintained.<BR>In this report, we introduce a case of saving energy by installing the new model of refining plate.
