Energy consumption is reduced when producing chemimechanical or mechanical pulp from pieces of pulp raw material, such as wood chips, sawdust, straw chaff or bagasse chaff, in a refiner, by subjecting the pieces of pulp raw material to bulk-density reducing plastic deformation between compression rolls prior to refining said material, this plastic deformation being continued until a reduction in bulk density of 35-65% is reached. |
