Abstract
The invention relates to a method of mixing pulp components in the manufacture of paper, in which method the pulp components to be mixed are led to a mixing point along tubes arranged inside each other. The pulp component flows are mixed by generating turbulence in them by means of the end of an inner tube, the cross-section of which end is wave-like. This turbulence is guided and its effect is intensified by means of form parts in connection with the mixing point, which form parts are arranged on the inner surface of the outer tube. Further, the invention relates to an arrangement implementing the mixing of pulp components in accordance with the method.
