Plant and process for carbonation

Abstract

The invention relates to a system and a method for carbonating a starting material, wherein the system comprises an inlet area (1), an outlet area (2), and a line (3) connecting the inlet area (1) with the outlet area (2) for transporting the material stream, wherein a carbonation section (4) is provided along the line (3) comprising a first grinding unit (5), a first classifying device (8), and a first return line (7), wherein the first classifying device (8) is arranged downstream of the first grinding unit (5) and is configured to separate the material stream into a coarse fraction and a fine fraction, wherein the first return line (7) is configured to return the coarse fraction to a first return area (9) arranged along the line (3) upstream of the first grinding unit (5), and wherein a carbon dioxide supply (6) is provided for supplying a carbon dioxide stream to the material stream.wherein the carbon dioxide supply (6) is provided in the first return section (9) and / or along the line (3) downstream of the first return section (9).
