Abstract
The present invention is concerned with an improvement in the mechanical treatment of wood fibers, 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 amount of energy at high intensity in the second stage. The present improvement allows a reduction in energy consumption as high as 18%.
