摘要： The present invention relates to a method of and reactor for in-line production of calcium carbonate into a target suspension flow. The method and reactor according to the invention are suitable for introducing and mixing lime milk and carbon dioxide into a target suspension flow so that the calcium carbonate crystals formed during their reaction are not allowed to precipitate onto the walls (12) of the reactor (10), because the reactor is provided with means (16, 18, 20) for preventing the carbonate crystals from attaching to the surfaces of the structures located in the reaction zone.
