Description

Nowadays, we have two major issues in the refining process.<BR>One is to reduce the power consumption from this most power consuming process in the stock preparation system.<BR>Second is the suitable refining method according to the changes of the resent stock fiber condition. Hard wood pulp, OCC and ONP are most commonly used as paper material. But recently, the ratio of plantation Hard wood pulp is rapidly increasing and the recycling rate of OCC and ONP are also increasing which both resulting to shorten the fiber length and becoming the lowering factor of fiber freeness.<BR>To use this short and weak fiber, not cutting refining but wet beating with less fiber cutting and property (strength) improvement could be the solution. In general, better Refining efficiency means the larger freeness drop with less power consumption and not wet beating. But the resent need in refining is to achieve good balance between these two, power reduction and property improvement with wet beating.<BR>In this report, we would introduce our approach to these issues with our newest technology, Aikawa Double Conifiner (ADC) and Finebar Refining plates, and its merits.
