Abstract: A method and a reactor to crystalize calcium carbonate and to form crystals in a liquid flow (F) with the concentration of 2.5% to 5% inside or on the surfaces of a fiber dispersion containing solid matter. The method includes feeding carbon dioxide (CO2) and lime milk (LM) (Ca(OH)2) into the liquid flow and reacting the CO2 with the Ca(OH)2 wherein the carbon dioxide (CO2) and/or lime milk (LM) is injected with a mixer crosswise into the liquid flow (F) and the injection is performed with a feed tube (2) to cause a dwell time of the crystallizing reaction of 0.5 to 10 seconds before a nozzle (20) of the reactor (1), after which the liquid flow (F) is mixed with the liquid or fiber suspension in container (4)
