OPTIMAL ENERGY REFINING METHOD FOR THE MECHANICAL TREATMENT OF WOOD FIBRES

摘要

The present invention is concerned with an improvement in the mechanical treatment of wood fibres, the improvement consisting in applying a large amount of energy at low intensity in the first stage of refining of the wood chips, and a small a mount of energy at high intensity in the second stage. The present improvement allows a r eduction in energy consumption as high as 18%.
