description In a method and device for loading the fibers that are contained in a fiber stock suspension with calcium carbonate by way of a chemical precipitation reaction, calcium oxide and/or calcium hydroxide are added to the fiber stock suspension. In order to trigger the precipitation reaction at least partially liquid carbon dioxide is injected into the reactor thereby ensuring the transformation of the starting substance calcium dioxide or calcium hydroxide into the reaction products calcium carbonate and water. The carbon dioxide can be added in an exclusively liquid state or partially in a liquid state and partially in a gaseous state.
