Kinetic evaluation of the hydration processes during pulp beating and refining

The kinetics of pulp swelling (WRV) during beating and refining was analysed. A new, simple and theoretically consistent method for the verification of experimental kinetic data of pulp swelling is described. According to this method, the influence of both mechanical action and water medium on pulp swelling during beating and refining was analysed. The rate of pulp swelling increases also by increasing both the specific edge loag of the refiner and the repulsive hydration forces.
