Abstract
The invention relates to a method and a mixer for mixing flows of a papermaking process. In the invention, a first flow is conveyed through a tube, and turbulence is generated in it by means of form parts located on the inner periphery of the tube. The mixing zone of the mixer comprises feed openings on the inner periphery of the tube for feeding a second flow from a feed channel outside the tube into the first flow, whereby the flows are mixed as a result of the turbulence generated by the form parts. According to a preferred embodiment of the invention, at least one form part comprises a feed opening.
